Diagnostic Test

BATTERY WAS DISCONNECTED
Has the battery been disconnected, lost it's charge, or been replaced recently?

Yes
- Disconnecting or replacing the battery will set this DTC. Erase the DTC.
- Perform 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
No
- Go to step 2
WAS QUICK LEARN PERFORMED
Has a Quick Learn procedure been performed?

Yes
- Performing a Quick Learn procedure will set this DTC. Erase the DTC.
- Perform 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
No
- Go to step 3
PCM REPLACED OR DISCONNECTED
Has the PCM been replaced or disconnected?

Yes
- Replacing or disconnecting the PCM will set this DTC. Erase the DTC.
- Perform 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
No
- Go to step 4
CHECK THE (A931) FUSED B(+) CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
  NOTE: Check connectors - Clean/repair as necessary.
3. Using a 12-volt test light connected to ground, check the (A931) Fused B(+) circuit in the PCM C1 harness connector.
  NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 5
  No
  - Repair the (A931) Fused B(+) circuit for an open. If the fuse is open make sure to check for a short to ground.
  - Perform 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
CHECK THE (Z902) GROUND CIRCUITS FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C2 harness connector.
3. Using a 12-volt test light connected to 12-volts, check both (Z902) Ground circuits in PCM C1 harness connector
  NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly for both ground circuits?
  
  Yes
  - Go to step 6
  No
  - Repair the (Z902) Ground circuit(s) for an open.
  - Perform 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
INTERMITTENT WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Test Complete.
