Inspection Procedure 2

INSPECTION PROCEDURE 2: The Right or Left Heated Door Mirror does not Operate

























CIRCUIT OPERATION

If either of the heated door mirrors do not operate normally, it may be due to malfunctions in the heated door mirror circuit or door mirror.

TROUBLESHOOTING HINTS

- Malfunction of the heated door mirror circuit
- Malfunction of the door mirror
- The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector.

DIAGNOSIS

STEP 1. Verify the operation of each heated door mirror.

Q. Which door mirror does not heat?

Door mirror (LH) : Go to Step 2.
Door mirror (RH) : Go to Step 8.
STEP 2. Check remote controlled mirror (LH) connector E-12 for loose, corroded or damaged terminals, or terminals pushed back in the connector.





Q. Is remote controlled mirror (LH) connector E-12 in good condition?

YES Go to Step 3.

NO Repair or replace the damaged component(s). Harness Connector Inspection. And then check to see that the heater function of the door mirror (LH) operates normally.

STEP 3. Check the heater of the door mirror (LH).

CAUTION:
When relocating the car between locations of extremely different temperatures
(warm and cold), leave the car in the location for a while to adapt to the temperature prior to checking it.





Check to see that the resistance shown in the graph is almost satisfied when measuring the resistance between terminal 1 and 3 of the remote controlled mirror (LH) connector E-12.

Q. Is the resistance normal?

YES Go to Step 4.

NO Replace the door mirror (LH). And then check to see that the heater function of the door mirror (LH) is operating normally.

STEP 4. Check the ground circuit between remote controlled mirror
(LH) connector E-12 and ground for open circuit. Measure the resistance at remote controlled mirror (LH) connector E-12.





(1)Disconnect remote controlled mirror (LH) connector E-12 and check at the wiring harness side connector.





(2)Measure the resistance value between terminal 3 and ground.

- The resistance should be 2 ohms or less.

Q. Is the measured resistance 2 ohms or less?

YES Go to Step 6.

NO Go to Step 5.

STEP 5. Check the wiring harness between remote controlled mirror
(LH) connector E-12 (terminal 3) and ground.









NOTE:
Also check intermediate connector C-25 for loose, corroded or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-25 is damaged, repair or replace the damaged component(s) as described in Harness Connector Inspection Harness Connector Inspection.

Q. Is the wiring harness between remote controlled mirror (LH) connector E-12 (terminal 3) and ground in good condition?

YES No action is necessary and testing is complete.

NO The wiring harness may be damaged. Repair the wiring harness as necessary. And then check to see that the heater function of the door mirror (LH) operates normally.

STEP 6. Check junction block C-215 for loose, corroded damaged terminal, or terminals pushed back in the connector.





Q. Is junction block C-215 in good condition?

YES Go to Step 7.

NO Repair or replace the damaged component(s). Harness Connector Inspection. And then check to see that the heater function of the door mirror (LH) operates normally.

STEP 7. Check the wiring harness between remote controlled mirror
(LH) connector E-12 (terminal 1) and junction block connector C-215 (terminal 3).













NOTE:
Also check intermediate connector C-25 for loose, corroded or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-25 is damaged, repair or replace the damaged component(s) as described in Harness Connector Inspection Harness Connector Inspection.

Q. Is the wiring harness between remote controlled mirror (LH) connector E-12 (terminal 1) and junction block connector C-215 (terminal 3) in good condition?

YES No action is necessary and testing is complete.

NO Repair the wiring harness as necessary. And then check to see that the heater function of the door mirror (LH) operates normally.

STEP 8. Check the remote controlled mirror (RH) connector E-01 for loose, corroded or damaged terminals, or terminals pushed back in the connector.





Q. Is the remote controlled mirror (RH) connector E-01 in good condition?

YES Go to Step 9.

NO Repair or replace the damaged component(s). Harness Connector Inspection. And then check to see that the heater function of the door mirror (RH) operates normally.

STEP 9. Check the heater function of the door mirror (RH).

CAUTION:
When relocating the car between locations of extremely different temperatures
(warm and cold), leave the car in the location for a while to adapt to the temperature prior to checking it.





Check to see that the resistance shown in the graph is almost satisfied when measuring the resistance between terminal 1 and 3 of the door mirror (RH) connector E-01.

Q. Is the resistance normal?

YES Go to Step 10.

NO Replace the door mirror (RH). And then check to see that the heater function of the door mirror (RH) operates normally.

STEP 10. Check the ground circuit between remote controlled mirror
(RH) connector E-01 and ground for open circuit. Measure the resistance at remote controlled mirror (RH) connector E-01.





(1)Disconnect remote controlled mirror (RH) connector E-01, and check at the wiring harness side connector.





(2)Measure the resistance value between terminal 3 and ground.

- The resistance should be 2 ohms or less.

Q. Is the measured resistance 2 ohms or less?

YES Go to Step 12.

NO Go to Step 11.

STEP 11. Check the wiring harness between remote controlled mirror
(RH) connector E-01 (terminal 3) and ground.









NOTE:
Also check intermediate connector C-09 for loose, corroded or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-09 is damaged, repair or replace the damaged component(s) as described in Harness Connector Inspection Harness Connector Inspection.

Q. Is the wiring harness between remote controlled mirror (RH) connector E-01 (terminal 3) and ground in good condition?

YES No action is necessary and testing is complete.

NO The wiring harness may be damaged. Repair the wiring harness as necessary. And then check to see that the heater function of the door mirror (RH) operates normally.

STEP 12. Check junction block C-215 for loose, corroded damaged terminal, or terminals pushed back in the connector.





Q. Is junction block C-215 in good condition?

YES Go to Step 13.

NO Repair or replace the damaged component(s). Harness Connector Inspection. And then check to see that the heater function of the door mirror (RH) operates normally.

STEP 13. Check the wiring harness between remote controlled mirror
(RH) connector E-01 (terminal 1) and junction block connector C-215 (terminal 3).













NOTE:
Also check intermediate connector C-09 for loose, corroded or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-09 is damaged, repair or replace the damaged component(s) as described in Harness Connector Inspection Harness Connector Inspection.
