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 termi-
nals 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-09 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.

Q: Is remote controlled mirror (LH) connector E-09 in good

condition?
YES : Go to Step 3.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. 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-09.
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 to between remote
controlled mirror (LH) connector E-09 and ground for open
circuit. Measure the resistance at remote controlled mirror
(LH) connector E-09.

(1) Disconnect remote controlled mirror (LH) connector E-09

and check at the wiring harness side connector.

(2) Measure the resistance value between terminal 3 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 5.

STEP 5. Check the wiring harness between remote
controlled mirror (LH) connector E-09 (terminal 3) and

ground.

NOTE: Also check intermediate connector C-26 for loose, cor-
roded or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-26 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between remote controlled mirror

(LH) connector E-09 (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-211 for loose, corroded
damaged terminal, or terminals pushed back in the
connector.

Q: Is junction block C-211 in good condition?

YES : Go to Step 7.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. And then check to see that the heater

function of the door mirror (LH) operates normally.
