`GWP of over 1,400. R—1234yf stays in
`the atmosphere for only 11 days, for a
`GWP of 4.
`
`R—1234yf refrigerant is considered
`mildly flammable and has thermody-
`namic properties similar to R-134a.
`R-1234yf standards require service
`equipment and evaporators with safety
`features that cover this concern. In
`
`addition, new SAE J2843~comp|iant
`Recovery/Recycle/Recharge machines
`must feature integrated refrigerant iden-
`tifiers or a USB port for connection with
`a hand—held identifier. Current identifiers
`
`cannot identify R—1234yf refrigerant.
`
`Technicians repairing or servicing
`motor vehicle air conditioning lMVACl
`systems in the U.S. must be trained and
`certified by an EPA approved organiza-
`tion. Certification is obtained by passing
`an EPA approved examination. Go to

`
`A new air conditioning refrigerant,
`R—1234yf, is being introduced in the new
`2013 Cadillac XTS and ATS. R-1234yf
`is a new environmentally—friendly
`refrigerant that has a 99.7% lower Global
`Warming Potential (GWP) than R-134a.
`GWP is a value used to compare differ-
`ent greenhouse gases that trap heat in
`the atmosphere. The new refrigerant
`received final approval from the U.S.
`Environmental Protection Agency (EPA)
`last year.
`
`The EPA and U.S Department of
`Transportation have adopted new
`standards for reducing greenhouse
`gas emissions from light-duty motor
`vehicles. In addition, the European Union
`has adopted similar standards. European
`regulations ban the use of R—134a in all
`new vehicles by 2017.
`
`The new refrigerant does not require
`significant changes to the design of
`automotive air conditioning systems.
`It also can be handled in service cen-
`
`ters in much the same way as Fl-134a,
`although it does require dedicated
`service equipment.
`
`R—1234yf stands for a specific com-
`pound: 1 - double bond, 2 - hydrogens,
`3 — carbons, 4- fluorines, yf — position of
`the fluoro atoms. It is a worldwide indus-
`
`try accepted solution fora low GWP
`refrigerant. The biggest benefit of the
`new refrigerant is that it breaks down
`faster in the atmosphere than R—134a.
`On average, R-134a has an atmospheric

`standard J2842-compliant evaporator
`cores. The J2842 standard states that
`
`an evaporator from an A/C system shall
`not be repaired or removed with the
`intention of using it again in the same
`or a different vehicle.
`
`There are new or revised service
`
`procedures for R-1234yf equipped vehi-
`cles (Refer to the appropriate Service

`
`GM installs fluorescent dye in the
`A/C refrigerant system during manufac-
`ture. The dye mixes with the A/C com-
`pressor oil throughout the refrigerant
`system. Leaks in the A/C system will
`be indicated in a light green or yellow
`color when using a leak detection lamp.
`Adding fluorescent dye would only be
`required after flushing the A/C system.
`Verifying some passive leaks may
`require using an SAE J2913-certified
`electronic leak detector, even though
`the system contains fluorescent dye.
`
`Retrofitting R-134a systems for
`R-1234yf refrigerant is not recommend-
`ed nor endorsed by GM.
`
`AIC Compressor Oils
`
`R-1234yf systems require the use
`of specific A/C compressor oils. In
`the GM Service Information, refer to
`HVAC > Specifications > Adhesives,
`Fluids, Lubricants and Sealers for proper
`type and use. Only GM lubricant is
`approved. The XTS A/C system uses
`PAG-PSD1, P/N 19260643 (10-4084).
`and the ATS uses PAG-NDl2, P/N
`19299051 (10-4085).
`
`New Tools and Equipment
`
`New dedicated tools and equip-
`ment are required by EPA regulations
`to service vehicles equipped with
`R-1234yf refrigerant.
`
`GM recommends the following
`equipment or equivalent.
`
`GE-50300 Recovery/Recycle/
`Recharge Machine for R-1234yf A/C
`Systems — (certified to SAE J2843l
`Performs gas analysis before gas
`recovery or fills with recovery/fill lock-
`out if gas is contaminated (less than
`
`2of8
`
`GE-50300
`
`98% R-1234yf). VIN input is required.
`The VIN is retrieved via an integrated
`VCI cable connected to the vehicle's
`
`OBD2 connector or may be manually
`entered. It records and prints VIN, pres-
`sures, temperature, recovered/charged
`amount, and gas analysis results.
`
`The GE-50300 Recovery/Recycle/
`Recharge Machine for R-1234yf A/C
`Systems requires product activation
`within 30 days of the machine's initial
`startup. Refer to the Quick Start Guide
`and follow the on-screen instructions
`
`to complete the on-line registration and
`product activation process.

`ACDelco Support for 'I'ech2Win
`
`Several diagnostic tool manufactur-
`ers have recently added ISO 22900
`PDU API (International Organization for
`Standardization 22900 Protocol Data
`
`Unit Application Programming Interface)
`functions and software/hardware to their
`SAE J2534 diagnostic scan tools. These
`companies may state that the new
`software/hardware allows their J2534
`devices to use Tech2Win, the PC-based
`application version of the Tech 2 and
`CANdi (Control Area Network diagnostic
`interface) module, which is built on the
`ISO 22900 PDU API standard.
`
`Technicians requiring technical
`support for these non—GM tools
`should direct inquiries to the tool manu-
`facturers. ACDelco offers support for the
`Tech 2 scan tool and Multiple Diagnostic
`Interface (MDI) tool, but
`
`4of8
`
`does not provide support for
`non—GM tools.
`
`ISO 22900 specifies the
`common software interface for
`
`diagnostic software applications.
`The purpose of the standard
`is to ensure that an applica-
`tion can operate on a common
`interface to communicate with a
`
`manufacturer's network protocol
`and vehicle bus systems.
`Tech2Win can be loaded onto
`
`a service center's Personal Computer
`(PC) or notebook computer through a
`T|S2Web subscription. A MDI tool also
`is required. Using Tech2Win enables
`technicians to take advantage of the
`computer power of the PC or notebook
`computer and the speed of the MDI,
`providing faster operation than a Tech 2.

`ACDe|co dexos1 5W20 Engine Oil
`
`Some 2013 GM models now being
`sold specify the use of dexos1"“ 5W20
`engine oil. Coming in early October,
`ACDe|co will offer dexos1 5W20
`
`engine oil in drums, and soon after,
`in quarts. 2013 models that specify
`dexos1 5W20 include the new Cadillac
`
`ATS and Chevrolet Malibu equipped
`with the 2.5L 4-cylinder engine and
`the Chevrolet Spark equipped with the
`1.2L 4-cylinder engine.
`
`Currently, dexos1 is available as a
`5W30 engine oil. Refer to the vehicle's
`owner manual to determine which vis-
`
`cosity of dexos1 is specified. The use
`of a viscosity of engine oil not specified
`may affect engine performance.
`
`If dexos1 5W20 engine oil is not avail-
`able, use a SAE 5W20 viscosity oil that
`is certified by the American Petroleum
`Institute (API) and displays the API
`"Starburst" symbol, which indicates
`that the oil meets the current engine
`protection standards and fuel economy
`requirements of the International
`Lubricant Standardization and Approval
`Committee, a joint effort of U.S. and
`Japanese automobile manufacturers.
`
`GM has required dexos1 as the
`factory fill and service fill in spark
`ignited engines worldwide since the
`2011 model year.
`
`The dexos specification was designed
`to meet the exacting requirements of
`GM's advanced engine technology,
`including direction injection, cam phas-
`ing, turbo charging and Active Fuel
`Management. The specification has
`gone through an extensive developmen-
`tal and testing process that requires a
`number of proprietary tests not includ-
`ed in current industry standards and
`sets performance criteria at a level that
`exceeds many current standards. The
`result is a high performance fluid that:
`
`0 Has improved viscometric proper-
`ties, creating less friction in the
`engine, contributing to improved
`fuel economy
`
`0 Resists aeration, which enables
`fuel-saving devices, such as vari-
`able valve timing, to work optimally
`
`0 Offers improved oxidation and
`deposit-forming tendencies allow-
`ing emission systems to operate
`longer and optimally

`
`For more information about the
`
`stringent quality standards of the dexos
`specification, visit the GM dexos web-
`site at www.gmdexos.com.
`
`ACDe|co dexos1 engine oil is avail-

`electronic control module provides a log-
`ically controlled (by operator or software)
`voltage potential to a component or
`another electronic control unit. This con-
`
`trolled voltage potential can be anything
`from vehicle ground to vehicle system
`voltage or a manipulated (pulsed/ampli-
`tude/frequency) voltage output.
`The tool of choice to test a control
`
`circuit is a test lamp. When the control
`circuit is activated, the test lamp will
`load the circuit. If there is any resistance
`in the circuit the test lamp will not light.
`
`Do Not Ilse a Digital Multimeter
`
`Why a Digital Multimeter (DMM)
`voltage reading is not used to test
`control circuits:
`
`0 The DMM does not load the circuit
`
`being tested
`
`0 The DMM's high input impedance
`(typically 10M ohms) would mask
`any resistive circuit condition up to
`1M ohm.
`
`6of8
`
`DMM voltage reading will not toggle
`or change states when commanding
`the control circuit on and off. This
`
`is caused by internal filtering in the
`control module, holding a charge
`(voltage) on the control circuit.
`
`Test lamps
`There have been two essential test
`
`lamps used over the years.
`
`0 Original - Low impedance (20 9)
`test lamp J-34142-B
`
`0 Newer— High impedance (200 9)
`test lamp J-35616-210
`
`Either test lamp works fine when
`testing a B+ (Battery Positive Voltage) or
`an ignition circuit. And up until the 2005
`model year both test lamps work fine
`testing any control circuit.
`
`However, when testing a 2006 model
`year and newer control module control
`circuit, the newer high impedance test
`lamp (J-35616-210) must be used in
`place of the original low impedance test
`lamp (J-34142-B).
`
`The issue is not with the test lamp
`but with the newer control modules.
`
`The original low impedance test lamp
`(J-34142-B) requires a high inrush
`current to fire off the bulb. When this
`
`happens, the control module shuts
`down the output driver. It's not because
`the output driver can't handle the
`temporary current spike (up to half an
`amp), but because the control mod-
`u|e’s software is calibrated to turn off
`
`the output driver at a very low current
`threshold and in a very short amount of
`time (typically, only a few milliseconds).
`
`Because the on-vehicle diagnostic
`validation is done using the newer test
`lamp (J-35616-210), it's important for
`technicians to also use it when testing
`control circuits.
`
`There are some control module out-
`
`puts that will not work even with the
`newer test lamp (J-35616-210). In these
`cases, the control circuit test steps in
`the Service Information call out alterna-
`
`tive diagnostic testing methods.

`Power Window Service
`
`Tips
`
`2008-2013 GM passenger cars and
`light-duty trucks
`
`The following service tips may be
`helpful if a front or rear side door win-
`dow is inoperative, rattles or squeaks,
`binds, operates slowly, fits poorly or is
`misaligned.
`
`Always check the appropriate Service
`Information for additional information on
`
`specific window operation and window
`regulator concerns.
`
`Window Intermittent Operation
`
`0 For 2—pin motors, first disconnect
`the motor connector and then
`
`apply a 12-volt power supply to
`the regulator motor to verify motor
`functions/activates. (This is not
`possible on 6 or 7—pin motors.)
`0 Check the wire harness for
`
`pinched/shorted wires. Check the
`switch for correct function and
`
`check the switch bezel for sticking
`switches. (If the motor activates
`
`and stops, check for window/regu-
`lator binding/alignment.)
`
`0 Check for proper glass alignmentl
`attachment. Position the window
`to access the side door window
`
`regulator window attachment bolts.
`Loosen the two bolts that attach
`
`the window to the window regula-
`tor or disengage the glass from
`the snap fit attachment. Slide the
`window up and down in the run
`channel. If it does not bind, properly
`adjust — do not replace the regula-
`tor. If it does bind, check for defec-
`tive seal and/or proper seal installa-
`tion, debris in the glass run channel
`and the glass run channel position.
`
`Regulator/Glass Rattles
`
`0 Check for any loose fasteners
`and re—torque to specification as
`required.
`
`0 Check that the glass is in the
`channel and reinstall if not posi-
`tioned correctly.
`
`Noisy Operation
`
`0 Check for other components in the
`glass path, such as wire harness,
`impact foam, lock rods or cables.

`
`It is critical when replacing a leaking
`or damaged power steering cooler to
`replace the cooler without introducing a
`lot of air into the system.
`
`When replacing a power steering
`cooler, first block off the hoses near the
`cooler connection with the appropriate
`clamps. Next, disconnect the cooler
`from the lines and remove the cooler.
`
`Pre—fi|| the new cooler on the bench
`
`and cap off the pre—fi|led cooler ends for
`installation.
`
`Install the new pre-filled cooler on the
`vehicle and remove the clamps on the
`hoses.
`
`Once installation is complete, be sure
`to follow the Power Steering System
`Bleed Procedure in the appropriate
`Service Information.
