INSPECTION PROCEDURE 2: Right or Left Heated Door Mirror does not OperateHeated Door Mirror Circuit (Part 1):
Heated Door Mirror Circuit (Part 2):
CIRCUIT OPERATION
If the heater function (heated door mirror) of either of the door mirrors does 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
STEP1. 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 the heated door mirror (LH).
CAUTION: When relocating the car between locations with 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 of terminal 1 and 2 of the door mirror (LH) connector under 2 or more different temperature conditions.
Q: Is the heater function (heated door mirror) of the door mirror normal?
YES : Go to Step 3.
NO : Replace the door mirror (LH). Check to see that the heater function (heated door mirror) of the door mirror (LH) is operating normally.
STEP 3. Check the ground circuit to the door mirror (LH). Test at the remote controlled mirror (LH) connector E-05.
1. Disconnect the remote controlled mirror (LH) connector E-05 and measure the resistance available at the wiring harness side of the connector.
2. Measure the resistance value between terminal 2 and ground.
- The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 6.
NO : Go to Step 4.
STEP 4. Check the remote controlled mirror (LH) connector E-05 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is the remote controlled mirror (LH) connector E-05 in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer to General (Electrial), Harness Connector Inspection. Check to see that the heater function (heated door mirror) of the door mirror (LH) operates normally.
STEP 5. Check the wiring harness between the remote controlled mirror (LH) connector E-05 (terminal 2) and ground.
NOTE: Also check intermediate connector C-118 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-118 is damaged, repair or replace the damaged component(s) as described in General (Electrial), Harness Connector Inspection.
Q: Are the wiring harness between the remote controlled mirror (LH) connector E-05 (terminal 2) and ground in good condition?
YES : No action is necessary and testing is complete.
NO : 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. Check to see that the heater function (heated door mirror) of the door mirror (LH) operates normally.
STEP 6. Check the remote controlled mirror (LH) connector E-05 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is the remote controlled mirror (LH) connector E-05 in good condition?
YES : Go to Step 7.
NO : Repair or replace the damaged component(s). Refer to General (Electrial), Harness Connector Inspection. Check to see that the heater function (heated door mirror) of the door mirror (LH) operates normally.
STEP 7. Check the wiring harness between the remote controlled mirror (LH) connector E-05 (terminal 1) and junction block connector C-205 (terminal 3).
NOTE: Also check intermediate connector C-118 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-118 is damaged, repair or replace the damaged component(s) as described in General (Electrial), Harness Connector Inspection.
Q: Are the wiring harness between the remote controlled mirror (LH) connector E-05 (terminal 1) and junction block connector C-205 (terminal 3) in good condition?
YES : No action is necessary and testing is complete.
NO : 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. Check to see that the heater function (heated door mirror) of the door mirror (LH) operates normally.
STEP 8. Check the heated door mirror (RH).
CAUTION: When relocating the car between locations with 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 of terminal 1 and 2 of the door mirror (RH) connector under 2 or more different temperature conditions.
Q: Is the heater function (heated door mirror) of the door mirror normal?
YES : Go to Step 9.
NO : Replace the door mirror (RH). Check to see that the heater function (heated door mirror) of the door mirror (RH) operates normally.
STEP 9. Check the ground circuit to the door mirror (RH). Test at the remote controlled mirror (RH) connector E-15.
1. Disconnect the remote controlled mirror (RH) connector E-15 and measure the resistance available at the wiring harness side of the connector.
2. Measure the resistance value between terminal 2 and ground.
- The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : No action is necessary and testing is complete.
NO : Go to Step 12.
STEP 10. Check the remote controlled mirror (RH) connector E-15 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is the remote controlled mirror (RH) connector E-15 in good condition?
YES : Go to Step 11.
NO : Repair or replace the damaged component(s). Refer to General (Electrial), Harness Connector Inspection. Check to see that the heater function (heated door mirror) of the door mirror (RH) operates normally.
STEP 11. Check the wiring harness between the remote controlled mirror (RH) connector E-15 (terminal 2) and ground.
NOTE: Also check intermediate connector C-15 for loose, corroded, or damaged terminals, or terminals pushed back in the connector If intermediate connector C-15 is damaged, repair or replace the damaged component(s) as described in General (Electrial), Harness Connector Inspection.
Q: Are the wiring harness between the remote controlled mirror (RH) connector E-15 (terminal 2) and ground in good condition?
