HIGH-VOLTAGE TRACTION BATTERY - HYBRID
Inspection and Verification
WARNING:Turn OFF the ignition switch for a minimum of 5 minutes before removing high-voltage cables. High-voltage cables and wiring are orange in color. The nominal high-voltage traction battery voltage (HVTB) is 330 V DC. Failure to follow these instructions may result in serious personal injury or death.
WARNING:Depower the high-voltage traction battery (HVTB) before carrying out any removal or installation procedures affecting the high-voltage battery system. Failure to follow this instruction may result in serious personal injury or death.
WARNING:Wear high-voltage insulated safety gloves and a face shield when working with high-voltage batteries or cables. The high-voltage insulated safety gloves should be of the appropriate safety and protection rating. Inspect the gloves before use and always wear them with the leather outer glove. Any hole in the rubber insulating glove is a potential entry point for high-voltage. Failure to follow these instructions may result in serious personal injury or death.
WARNING:When servicing the high-voltage system, establish a buffer zone per the specified procedure. Failure to follow this instruction may result in serious personal injury or death.
NOTE:Verify the service disconnect plug is correctly inserted and locked into the lock position.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart
1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
2. Verify the 12-volt battery condition. Carry out the battery condition test. See Testing and Inspection.
3. If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
NOTE:Make sure to use the latest scan tool software release.
4. If the scan tool does not communicate with the VCM:
- Check the VCM connection to the vehicle.
- Check the scan tool connection to the VCM.
- See - Pinpoint Test 17: No Power To The Scan Tool.
NOTE:The vehicle communication module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.
5. If the scan tool does not communicate with the vehicle:
- Verify the ignition key is in the ON position.
- Verify the scan tool operation with a known good vehicle.
- See - Pinpoint Test 1: The PCM Does Not Respond To The Scan Tool.
6. Carry out the network test.
- If the scan tool responds with no communication for one or more modules, see - Pinpoint Test 16: No Medium Speed Controller Area Network (MS-CAN) Communication, All Modules Are Not Responding.
- If the network test passes, retrieve and record continuous memory DTCs.
7. If the DTCs retrieved are related to a driveability concern, see Tribute Hybrid Powertrain Control/Emissions Diagnosis to continue diagnosis.
8. If the DTCs retrieved are related to the concern, see - Battery Control Module (BCM) DTC Chart to continue diagnosis.
9. If the DTCs retrieved are not found in the Traction Battery Control Module (TBCM) DTC Chart, see -- Control Systems Hybrid - B, C, P And U Codes - DTC Chart.
10. If no DTCs related to the concern are retrieved, see -- Symptom Related Diagnostic Procedures.
