Diagnostic Test

TEST FOR INTERMITTENT CONDITION
NOTE:
Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.
1. Turn the ignition on.
  NOTE:
  Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. With the scan tool, read the module status.
  NOTE:
  Check the TIPM for any active CAN hardware DTCs, perform DTC before proceeding.
  
  Does the scan tool indicate that the module is active on the bus?
  
  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

1. Turn the ignition off.
2. Disconnect the Shifter Assembly harness connector.
3. Using a 12-volt test light connected to 12-volts, check the (Z911) Ground circuits.
  Does the test light illuminate brightly for each circuit?
  
  Yes
  - Go To 3
  No
  - Repair the open in the (Z911) Ground circuit.
  - Perform the appropriate transmission verification test. For vehicles with NAG1 transmissions. Refer to STANDARD PROCEDURE . For all others, refer to the appropriate Testing & Diagnostics article in Engine Performance .
CHECK THE (F1) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT FOR AN OPEN OR SHORT

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F1) Fused Ignition Switch Output (Run-Start) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 4
  No
  - Repair the open or short in the (F1) Fused Ignition Switch Output (Run-Start) circuit.
  - Perform the appropriate transmission verification test. For vehicles with NAG1 transmissions. Refer to STANDARD PROCEDURE . For all others, refer to the appropriate Testing & Diagnostics article in Engine Performance .
CHECK THE (D52) AND (D51) CAN C BUS CIRCUITS FOR AN OPEN

1. Turn the ignition off.
2. Disconnect the TIPM C7 harness connector.
3. Measure the resistance of the (D51) CAN C Bus (-) circuit between the Shifter Assembly harness connector and the TIPM C7 harness connector.
4. Measure the resistance of the (D52) CAN C Bus (+) circuit between the Shifter Assembly harness connector and the TIPM C7 harness connector.
  Are the resistances below 5.0 Ohms?
  
  Yes
  - Replace the ESM, which is integral to the Shifter Assembly, in accordance with the Service Information. For vehicles with NAG1 transmissions. Refer to SHIFTER, TRANSMISSION, REMOVAL . For all others, refer to SHIFTER, TRANSMISSION, REMOVAL .
  - Perform the appropriate transmission verification test. For vehicles with NAG1 transmissions. Refer to STANDARD PROCEDURE . For all others. Refer to the appropriate Testing & Diagnostics article in Engine Performance .
  No
  - Repair the open in the (D52) or (D51) CAN C Bus circuit.
  - Perform the appropriate transmission verification test. For vehicles with NAG1 transmissions. Refer to STANDARD PROCEDURE . For all others. Refer to the appropriate Testing & Diagnostics article in Engine Performance .
