Diagnostic Test

CHECK ENGINE DTCs
NOTE: Make sure the battery is fully charged before proceeding.
1. With the scan tool, read ENGINE DTCs
  Are there any active BATTERY OR CHARGING SYSTEM DTCs?
  
  No
  - Go to step 2
  Yes
  - Perform the appropriate diagnostic procedure.
  - For gas engines. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing .
TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase the DTCs.
2. Start the engine and run for two minutes.
3. With the scan tool, read the DTCs.
  Does the scan tool display B210D-BATTERY VOLTAGE LOW?
  
  Yes
  - Go to step 3
  No
  - The conditions that caused this code to set are not present at this time. Using the SYSTEM WIRING DIAGRAMS as a guide, inspect the wiring and connectors.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .

1. Disconnect the Door Module C1 connector
2. Test for a resisted (A931) Fused B(+) circuit by connecting a 12-volt test light between the (A931) Fused B(+) circuit and the (Z- - -) Ground circuit in the Door Module connector. 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
  - Replace the Door Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
  No
  - Test the (A931) Fused B(+) and the Ground circuits to determine which one has the high resistance. Repair the (A931) Fused B(+) circuit or the (Z- - -) Ground circuit for high resistance.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
