Q. Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
Repair the wiring harness.

STEP 4. Resistance measurement E-101 inside rear view mirror assembly connector.
(1)Disconnect the connector, and measure at the wiring harness side.
(2)Measure the resistance value between terminal 2 and earth.
OK: Continuity (Less than 2 Ω)

Q. Is the check result normal?
Go to Step 6.
Go to Step 5.

STEP 5. Check the wiring harness between E-101 inside rear view mirror assembly connector terminal No.2 and earth.

Q. Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
Repair the wiring harness.

STEP 6. Voltage measurement at E-101 inside rear view mirror assembly connector.
(1)Disconnect inside rear view mirror assembly connector E-101, and measure the voltage at the harness side.
(2)Turn the ignition switch to the "ON" position.
(3)Shift the selector lever to the "R" range. <A/T>
(4)Shift the lever to the "R" position. <M/T>
(5)Measure the resistance value between terminal 3 and earth.
OK: Approximately 12 volts (battery positive voltage)

Q. Is the check result normal?
Go to Step 17.
NO <A/T> : Go to Step 7.
NO <M/T> : Go to Step 12.

STEP 7. Connector check: C-05 inhibitor switch connector

Q. Is the check result normal?

STEP 9. Check the ignition switch (IG1) circuit to the inhibitor switch. Measure the voltage at inhibitor switch connector C-05.
(1)Disconnect inhibitor switch connector C-05 and measure the voltage available at the wiring harness side of the connector.
(2)Turn the ignition switch to the "ON" position.
(3)Measure the resistance value between terminal 7 and earth.
OK: Approximately 12 volts (battery positive voltage)

Q. Is the check result normal?
Go to Step 11.
Go to Step 10.

STEP 10. Check the wiring harness between C-05 inhibitor switch connector terminal No.7 and the ignition switch (IG1).
note Prior to the wiring harness inspection, check intermediate connectors D-225 and C-229, junction block connectors D-401 and D-403, and repair if necessary.

Q. Is the check result normal?
No action is necessary and testing is complete.
The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary.

STEP 11. Check the wiring harness between E-101 inside rear view mirror assembly connector terminal No.3 and C-05 inhibitor switch connector terminal No.8.
note Prior to the wiring harness inspection, check intermediate connectors D-130, D-225 and D-230, and repair if necessary.

Q. Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
Repair the wiring harness.

STEP 12. Connector check: C-17 back-up lamp switch connector

Q. Is the check result normal?
Go to Step 13.
Repair or replace the damaged component(s). Refer to GROUP 00, Harness Connector Inspection .

STEP 13. Check the back-up lamp switch.

Q. Is the check result normal?
Go to Step 14.
Repair the back-up lamp switch.

STEP 14. Check the ignition switch (IG1) circuit to the backup light switch. Measure the voltage at back-up lamp switch connector C-17.
(1)Disconnect inside rear view mirror assembly connector E-101, and measure the voltage at the harness side.
(2)Turn the ignition switch to the "ON" position.
(3)Measure the resistance value between terminal 2 and earth.
OK: Approximately 12 volts (battery positive voltage)
