DTC 65

DTC 65 (P1580): Battery Current Circuit Problem
1. Reset the MCM.
2. Turn the ignition switch ON (II).
Is DTC 65 indicated?
YES-Go to step 3.
NO-Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the battery current sensor and at the BCM module.
3. Turn the ignition switch OFF.
4. Turn the battery module switch OFF.
5. Remove the IPU lid.
6. Turn the ignition switch ON (II).





7. Measure voltage between battery current sensor 3P connector terminals No. 1 and No. 3.
Is there about 24 V?
YES-Go to step 8.
NO-Go to step 12.
8. Turn the ignition switch OFF.
9. Disconnect the battery current sensor 3P connector.
10. Reset the MCM.
11. Turn the ignition switch ON (II).
Is DTC 65 indicated?
YES-Substitute a known-good BCM module and recheck. If the symptom/indication goes away, replace the original BCM module.
NO-Replace the battery module.
12. Turn the ignition switch OFF.
13. Disconnect the battery current sensor 3P connector.
14. Turn the ignition switch ON (II).
15. Measure voltage between battery current sensor 3P connector terminals No. 1 and No. 3.
Is there about 24 V?
YES-Replace the battery module.
NO-Go to step 16.





16. Measure voltage between BCM module connector terminals A3 and A12, and between A16 and A12.
Is there about 12 V or - 12 V?
YES-Repair open in the wire that did not have voltage in step 15.
NO-Go to step 17.
17. Disconnect BCM module connector A (26P).
18. Check for continuity between body ground and BCM terminals A3 and A16 individually.
Is there continuity?
YES-Repair short in the wire between the BCM module and the battery current sensor.
NO-Replace the BCM module.
