P0ACD

DTC P0ACD (54): Battery Module Temperature Sensor 3 Circuit High Voltage
1. Turn the ignition switch ON (II).
2. Check the IMA BATTERY MODULE TEMPERATURE SENSOR 3 VOLTAGE (IMA BATTERY MODULE TEMPERATURE SENSOR 3) in the DATA LIST with the HDS.
Is about 4.95 V or more (-40°F 40°C) or less) indicated?
YES - Go to step 3.
NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the battery module and the BCM module.

3. Check for IMA system Temporary DTCs or DTCs with the HDS.
Are DTC P0A9E (50), P0AC8 (52), and P0ACD (54) indicated at the same time?
YES - Go to step 14.
NO - Go to step 4.

4. Turn the ignition switch OFF.
5. Turn the battery module switch OFF.
6. Remove the IPU lid.
7. Disconnect junction board 12P connector.
8. Connect junction board 12P connector terminal No. 9 to body ground with a jumper wire.





9. Turn the ignition switch ON (II).
10. Check the IMA BATTERY MODULE TEMPERATURE SENSOR 3 VOLTAGE (IMA BATTERY MODULE TEMPERATURE SENSOR 3) in the DATA LIST with the HDS.
Is about 4.95 V or more (-40°F (40°C) or less) indicated?
YES - Go to step 11.
NO - Replace the battery module, then go to step 24.

11. Turn the ignition switch OFF.
12. Disconnect BCM module connector A (40P).
13. Check for continuity between BCM module connector terminal A15 and junction board 12P connector terminal No. 9.





Is there continuity?
YES - Go to step 30.
NO - Repair open in the wire between the battery module and the BCM module (A15), then go to step 24.

14. Turn the ignition switch OFF.
15. Turn the battery module switch OFF.
16. Remove the IPU lid.
17. Connect junction board 12P connector terminal No. 10 to body ground with a jumper wire.





18. Turn the ignition switch ON (II).
19. Check the IMA BATTERY MODULE TEMPERATURE SENSOR 1 VOLTAGE (IMA BATTERY MODULE TEMPERATURE SENSOR 1), IMA BATTERY MODULE TEMPERATURE SENSOR 2 VOLTAGE (IMA BATTERY MODULE TEMPERATURE SENSOR 2), and IMA BATTERY MODULE TEMPERATURE SENSOR 3 VOLTAGE (IMA BATTERY MODULE TEMPERATURE SENSOR 3) in the DATA LIST with the HDS.
Are they about 4.95 V or more (-40°F (-40°C) or less) indicated?
YES - Replace the battery module, then go to step 24.
NO - Go to step 20.

20. Turn the ignition switch OFF.
21. Disconnect the junction board 12P connector.
22. Disconnect BCM module connector A (40P).
23. Check for continuity between BCM module connector terminal A6 and junction board 12P connector terminal No. 10.





Is there continuity?
YES - Go to step 30.
NO - Repair open in the wire between the battery module and the BCM module (A6), then go to step 24.

24. Turn the ignition switch OFF.
25. Reconnect all connectors.
26. Reinstall the IPU lid, then turn the battery module switch ON.
27. Turn the ignition switch ON (II).
28. Reset the BCM module with the HDS.
29. Check for IMA system Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P0ACD (54) is indicated, check for poor connections or loose terminals at the battery module and the BCM module, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO - Troubleshooting is complete.

30. Reinstall the IPU lid, then turn the battery module switch ON.
31. Update the BCM module if it does not have the latest software, or substitute a known-good BCM module.
32. Check for IMA system Temporary DTCs or DTCs with the HDS.
Is DTC P0ACD (59) indicated?
YES - Check for poor connections or loose terminals at the battery module and the BCM module. If the BCM module was updated, substitute a known-good BCM module, then recheck. If the BCM module was substituted, go to step 1.
NO - If the BCM module was updated, troubleshooting is complete. If the BCM module was substituted, replace the original BCM module. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
