DIAGNOSTIC TEST

  1. TEST FOR INTERMITTENT CONDITION Turn the ignition on. NOTE: Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts. NOTE: Make sure the scan tool is updated to the latest software. NOTE: If the scan tool displays any error messages involving the Diagnostic CAN C circuits, diagnose and repair the error message before proceeding. Refer to the «DIAGNOSTIC CODE INDEX»(ref-466007) . With the scan tool, attempt to communicate with the TIPM. Does the scan tool communicate with the TIPM? Yes The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals. No Go To 2 .
  2. FUSED B(+) CIRCUITS OPEN AT TIPM Disconnect the scan tool from the DLC. Using a 12-volt test light connected to ground, and using the wiring diagram as a guide, check all Fused B(+) circuits at the TIPM. Does the test light illuminate brightly for each circuit? Yes Go To 3 . No Repair the open or short in the Fused B(+) circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) .
  3. FUSED IGNITION SWITCH OUTPUT CIRCUITS OPEN AT TIPM Turn the ignition on. Using a 12-volt test light connected to ground, and using the wiring diagram as a guide, check each Fused Ignition Switch Output circuit at the TIPM. Does the test light illuminate brightly for each circuit? Yes Go To 4 . No Repair the open in the Fused Ignition Switch Output circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) .
  4. GROUND CIRCUITS OPEN AT TIPM Turn the ignition off. Using a 12-volt test light connected to 12-volts, and using the wiring diagram as a guide, check all ground circuits at the TIPM. Does the test light illuminate brightly on each circuit? Yes Go To 5 . No Repair the open in the ground circuit that did not light the test light. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) .
  5. CHECK THE (D72) DIAGNOSTIC CAN C (+) CIRCUIT FOR AN OPEN Disconnect the TIPM C7 harness connector. Measure the resistance of the (D72) Diagnostic CAN C (+) circuit between the TIPM C7 harness connector and the DLC. Is the resistance below 5.0 Ohms? Yes Go To 6 . No Repair the open in the (D72) Diagnostic CAN C (+) circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) .
  6. CHECK THE (D71) DIAGNOSTIC CAN C (-) CIRCUIT FOR AN OPEN Measure the resistance of the (D71) Diagnostic CAN C (-) circuit between the TIPM C7 harness connector and the DLC. Is the resistance below 5.0 Ohms? Yes Go To 7 . No Repair the open in the (D71) Diagnostic CAN C (-) circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) .
  7. CHECK THE DIAGNOSTIC CAN C CIRCUITS FOR A SHORT TOGETHER Measure the resistance between the (D72) Diagnostic CAN C (+) circuit and the (D71) Diagnostic CAN C (-) circuit at the TIPM C7 harness connector. Is the resistance above 10k Ohms? Yes Replace the Totally Integrated Power Module in accordance with the Service Information. Refer to «MODULE, TOTALLY INTEGRATED POWER (TIPM) , REMOVAL»(ref-465939-S25536192582012042300000) . Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) . No Repair the short between the (D72) Diagnostic CAN C (+) circuit and the (D71) Diagnostic CAN C (-) circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) .

  1. VERIFY DIAGNOSTIC TROUBLE CODE (DTC) IS STORED NOTE: Stored faults may indicate a customer perceived intermittent condition. NOTE: Make sure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding. Turn the ignition on. With the scan tool, read stored DTCs. Is this DTC stored? Yes Go To 2 . No Go to «DIAGNOSTIC CODE INDEX»(ref-466007) and perform the appropriate diagnostic procedure.
  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 C hardware electrical, battery, ignition voltage, VIN missing/mismatch, or TIPM configuration DTCs present with matching environmental data? Yes These DTCs may have been the result of other service procedures performed. Clear the DTCs. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) . No Go To 3 .
  3. VERIFY INTERMITTENT LOST COMMUNICATION DTC - WIRING CONCERNS With the scan tool, view the vehicle network. 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, using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. Repair as necessary. No Go To 4 .
  4. VERIFY INTERMITTENT LOST COMMUNICATION DTC - OFFENDING MODULE With the scan tool, view the vehicle network. 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 a TSB related to this offending module. No Go To 5 .
  5. VERIFY INTERMITTENT LOST COMMUNICATION DTC - REPORTING MODULE With the scan tool, view the vehicle network. Is there ONLY ONE ECU with stored DTCs "Logged Against" the module? Yes Check for a TSB related to the module that set this DTC. No Verify if the vehicle was recently in for this type of service. Otherwise, using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. Repair as necessary.
