DIAGNOSIS PROCEDURE

STEP 1. Check the inhibitor switch.

Refer to

Q. Is the check result normal?

	Go to Step 2.

	Replace the inhibitor switch.

STEP 2. Connector check: C-05 Inhibitor switch connector, D-225 intermediate connector, D-39 A/T-ECU connector <4M4> or D-216 engine-A/T-ECU connector <6G7>

Check for the contact with terminals.

Q. Is the check result normal?

	Go to Step 3.

	Repair the defective connector.

STEP 3. Check the harness between inhibitor switch connector C-05 terminal No.3, 2, 8, 1 and A/T-ECU connector D-39 terminal No.67, 56, 66, 55 <4M4> or engine-A/T-ECU connector D-216 terminal No.76, 75, 67, 66 <6G7>.

Check the output line for open circuit or short circuit.

Q. Is the check result normal?

	Go to Step 4.

	Repair the wiring harness.

STEP 4. M.U.T.-III data list

Item 34: Inhibitor switch (Refer to data list reference table

Q. Is the check result normal?

	Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).

	Replace the A/T-ECU <4M4> or engine-A/T-ECU <6G7>.
