NO -
Go to Step 12 .
  1. Remove the No. 12 (10 A) fuse from the under-dash fuse/relay box.

  1. Check for continuity between clutch actuator subharness 10P connector terminal No. 2 and body ground.
Is there continuity?
YES -
Repair a short in the wire between the No. 12 (10 A) fuse in the under-dash fuse/relay box and the clutch actuator subharness 10P connector, and replace the No. 12 (10 A) fuse.■
NO -
Remove the clutch actuator assembly, and check for clutch actuator subharness. 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.
