NOTE: Check harness after checking intermediate connectors
D-16, C-90 and C-28. If intermediate connectors are damaged,
repair or replace them. Refer to GROUP 00E, Harness Con-
nector Inspection

P.00E-2

. Then go to Step 12.

Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 12.
NO : Repair it. Then go to Step 12.

STEP 9. Check connector C-56 at ECM <M/T> or connector
C-50 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 10.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 12.
