Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

CHECK FOR AN ACTIVE DTC
WARNING:
On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must carry out the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury.

Read the HIGH-VOLTAGE SAFETY PROCEDURES. Refer to HIGH VOLTAGE SAFETY PROCEDURES

When the HIGH-VOLTAGE POWER-DOWN PROCEDURE is necessary. Refer to HIGH VOLTAGE POWER DOWN .
1. With the scan tool, read Battery Pack Control Module (BPCM) DTCs and record on the repair order.
  NOTE:
  If the Battery Pack Control Module (BPCM) is not present on the CAN Bus or U0111-00 DTC is active, establish communication with the BPCM before proceeding.
2. Record the Freeze Frame Data (If available), Event Data (If available), and Environmental Data.
3. Repair any related Occupant Restraint Controller (ORC) DTCs before continuing.
4. With the scan tool, erase DTCs.
  NOTE:
  Most BPCM DTCs will require the EVSE to be disconnected in order to clear.
5. Using the recorded data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
6. With the scan tool, read BPCM DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
CHECK THE (R414) AIRBAG DEPLOYMENT SIGNAL 2 CIRCUIT FOR FAILURE
1. Test the circuit for an open, high resistance, short to ground or short to voltage condition.
2. Check related terminals for fit and connection integrity.
  Were there any problems found?
  
  Yes
  - Repair the wiring in accordance with the Service Information.
  - Perform the BATTERY PACK CONTROL MODULE (BPCM) VERIFICATION TEST. Refer to: HV VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (R41) AIRBAG DEPLOYMENT SIGNAL CIRCUIT FOR FAILURE
1. Test the circuit for an open, high resistance, short to ground or short to voltage condition.
2. Check related terminals for fit and connection integrity.
  Were there any problems found?
  
  Yes
  - Repair the wiring in accordance with the Service Information.
  - Perform the BATTERY PACK CONTROL MODULE (BPCM) VERIFICATION TEST. Refer to: HV VERIFICATION TEST .
  No
  - Replace the Occupant Restraint Controller (ORC) in accordance with the Service Information.
  - If the DTC is still present after replacing the ORC, replace the Primary and Secondary High Voltage Battery Packs in accordance with the Service Information. Refer to HIGH VOLTAGE BATTERY, REMOVAL AND INSTALLATION .
  - Perform the BATTERY PACK CONTROL MODULE (BPCM) VERIFICATION TEST. Refer to: HV VERIFICATION TEST .
