Scheme 6

1. VERIFY DTC IS STORED NOTE: Stored faults may indicate a customer perceived intermittent condition. NOTE: Ensure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding. With the scan tool, read stored DTCs. Is this DTC stored? Yes Go To step 2 . No Diagnose the active DTC. Refer to appropriate ELECTRICAL DIAGNOSTICS article Perform «BODY VERIFICATION TEST - VER 1»(ref-304477-S32224544052008111000000) .
2. CHECK THE ENVIRONMENTAL DATA With the scan tool, read the loss of communication environmental data. Does the loss of communication environmental odometer data match up to any of the previous service procedures listed in the possible causes or are there any stored CAN B or C hardware electrical, battery, ignition voltage, VIN missing/mismatch, TIPM configuration DTCs present with match environmental data? Yes These DTCs may have been the result of other service procedures performed. Clear DTCs. Perform «BODY VERIFICATION TEST - VER 1»(ref-304477-S32224544052008111000000) . No Go To step 3 .
3. VERIFY INTERMITTENT LOST COMMUNICATION DTC-WIRING CONCERNS Turn the ignition on. With the scan tool, select Network View and select Advanced. Is there more than one ECU with stored DTCs "Logged Against" the module and one or more lost communication DTCs stored in the offending module? Yes Verify if the vehicle was recently in for this type of service. Otherwise, visually inspect the related wiring harness for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals. Repair as necessary. No Go To step 4 .
4. VERIFY INTERMITTENT LOST COMMUNICATION DTC-OFFENDING MODULE Turn the ignition on. With the scan tool, select Network View and select Advanced. Is there more than one ECU with stored DTCs "Logged Against" the module and NO lost communication DTCs stored in the offending module? Yes Check for TSB related to this offending module. No Go To step 5 .
5. VERIFY INTERMITTENT LOST COMMUNICATION DTC-REPORTING MODULE Turn the ignition on. With the scan tool, select Network View and select Advanced. Is there ONLY ONE ECU with stored DTCs "Logged Against" the module? Yes Check for TSB related to the module that set this DTC. No Verify if the vehicle was recently in for this type of service. Otherwise, visually inspect the related wiring harness for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals. Repair as necessary.

1. Perform Body Verification Test Disconnect all jumper wires and reconnect all previously disconnected components and connectors. Ensure that all accessories are turned off. Ensure that the battery is fully charged. If the battery was disconnected for any reason, refer to «STANDARD PROCEDURE»(ref-304460-S38978467932008111000000) for accessory calibration procedures. If the TIPM has been replaced, the Pinion Factor MUST be programmed into the TIPM. Refer to the scan tool for program procedure. Turn the ignition on. With the scan tool, record and erase DTCs from all modules. (Export only) If the Intrusion Transceiver Module (ITM) and/or Siren was replaced, select ITM from the from the scan tool ECU view menu then "Misc. Functions" and perform the applicable replacement procedure. If the vehicle is equipped with Express Up Power Windows and the battery was disconnected during repairs, run both front windows all the way down. Next, run the window all the way up and hold the switch in the up position for five seconds to re-initialize the express up feature. Perform this step only if diagnosing faults related to the HVAC system. The Manual Temperature Control (MTC) is not on the Bus and not addressed with a scan tool. Perform the following to clear DTCs from the MTC: 1. Turn the blower control on. 2. Press the A/C mode switch down, turn the blower control to off, wait until both LEDs illuminate (approximately 5 seconds) and then release the A/C mode switch. 3. When the A/C status indicator begins flashing DTCs, set the Mode switch to the floor position, simultaneously press the A/C mode switch and the EBL mode switch down until both LEDs start flashing (approximately 5 seconds) and then release the mode switches. For vehicles equipped with Automatic Temperature Control (ATC), if repairs were made to any of the HVAC doors, linkage, door actuators, or door actuator circuits, run the actuator calibration function by selecting the following from the scan tool menu: select HVAC, More Options, System Tests, Actuator Calibration Test, and Start. Follow the directions displayed by the scan tool. Allow the test to run to completion before proceeding. For vehicles equipped with MTC, if repairs were made to any of the HVAC doors, linkage, door actuators, or door actuator circuits, run the door calibration function by performing the following: 1. Turn the ignition on. 2. Turn the blower control to off. 3. Press the EBL mode switch down, turn the blower control on, wait until the EBL LED starts flashing (approximately 5 seconds) and then release the mode switch. Wait approximately 90 seconds for the calibration process to run to completion before proceeding. Turn the ignition off, wait 10 seconds, and then turn the ignition on. Operate all functions of the system that caused the original concern. If a repair or module replacement was done to the power windows, operate the motor fully down and then to the full up position and stall it for 2 seconds. With the scan tool, select ECU View and check for DTCs in the modules. Perform this step only if diagnosing faults related to the MTC HVAC system. NOTE: The A/C status indicator displays active DTCs when the EBL status indictor is not illuminated and stored DTCs when the EBL status indicator is illuminated. Perform the following to read DTCs from the MTC: 1. Turn the blower control on. 2. Press the A/C mode switch down, turn the blower control to off, wait until both LEDs illuminate (approximately 5 seconds) and then release the A/C mode switch. 3. Read the DTCs from the flashing A/C status indicator. Are DTCs present in any of the modules or is the original condition still present? Yes The repair is not complete. Refer to the «DIAGNOSTIC CODE INDEX»(ref-304477-S34318650902008111000000) for the DTC or symptom that is still present. No The repair is complete.
