P1574
DTC P1574 (68): Battery Module Temperature Signal Circuit MalfunctionNOTE: If the IPU module fan duct is blocked, DTC P1574 (68) may be detected.
1. Turn the ignition switch ON (II).
2. Check for IMA system Temporary DTCs or DTCs with the HDS.
Is DTC P1448 (63) indicated?
YES - Do the troubleshooting for DTC P1448 (63).
NO - Go to step 3.
3. Note the value of IMA BATTERY TEMPERATURE SENSOR 1, IMA BATTERY TEMPERATURE SENSOR 2, and IMA BATTERY TEMPERATURE SENSOR 3 in the DATA LIST with the HDS.
4. Check the SOC in the DATA LIST with the HDS. If the SOC is higher than 70%, start the engine several times until the SOC is less than 70%.
5. Compare the value of IMA BATTERY TEMPERATURE SENSOR 1, IMA BATTERY TEMPERATURE SENSOR 2, and IMA BATTERY TEMPERATURE SENSOR 3 in the DATA LIST with the HDS.
Did IMA BATTERY TEMPERATURE SENSOR 1, IMA BATTERY TEMPERATURE SENSOR 2, and IMA BATTERY TEMPERATURE SENSOR 3 change 1.0°F (0.5°C) or more?
YES - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the battery module and the BCM module.
NO - Go to step 6.
6. Check the IPU module air duct and IPU module fan for disconnections, damage, or obstructions.
Are the IPU module air duct and the IPU module fan OK?
YES - Replace the battery module, then go to step 8.
NO - Repair the IPU module air duct or IPU module fan, then go to step 8.
7. Turn the ignition switch ON (II).
8. Reset the BCM module with the HDS.
9. Check for IMA system Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P1574 (68) 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.
