DTC Troubleshooting: P0904 (162-2)
  1. Check for continuity between select actuator motor 6P connector terminal No. 5 and change actuator subharness B 8P connector terminal No. 6.
Is there continuity?
YES -
Remove the clutch actuator assembly, and check for change actuator subharness A. If the wire harness is OK, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM. ■
NO -
Repair an open in the wire of the change actuator subharness B.■
