Power Mirror Control System

INSPECTION




1. W/O Memory:




INSPECT LEFT SIDE MIRROR SWITCH CONTINUITY




2. INSPECT RIGHT SIDE MIRROR SWITCH CONTINUITY

If continuity is not as specified, replace the switch.
If continuity is as specified.inspect the switch circuit.




3. W/ Memory:
INSPECT LEFT SIDE MIRROR SWITCH CONTINUITY
If continuity as specified, replace the switch.




4. W/ Memory:
INSPECT MIRROR SWITCH RESISTANCE

HINT:
- Set the Left/Right adjustment switch to either position on the left or right.
- Measure resistance between terminals 7 and 9 at each switch position, as shown in the chart.

If resistance as specified, replace the switch.







5. INSPECT MIRROR SWITCH CIRCUIT
Disconnect the connector from the switch and inspect the connector on the wire harness side.

If the circuit is not as specified, inspect the circuits connected to other parts.




6. INSPECT MIRROR SWITCH INDICATOR LIGHT OPERATION
Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 6, and check that the indicator light does not light up, replace the switch.

7. W/O Mirror defogger and driving position memory:
INSPECT MIRROR MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the mirror turns to the left side.




b. Reverse the polarity, and check that the mirror turns to the right side.




c. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the mirror turns upward.




d. Reverse the polarity, and check that the mirror turns downward.

If operation is not as specified, replace the mirror assembly.

8. W/ Mirror defogger:
INSPECT MIRROR MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the mirror turns to the left side.




b. Reverse the polarity, and check that the mirror turns downward.

If operation is not as specified, replace the mirror assembly.




c. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 2, and check that the mirror turns upward.




d. Reverse the polarity, and check that the mirror turns downward.
If operation is not as specified, replace the mirror assembly.

9. W/ Driving position memory:
INSPECT MIRROR POSITION MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the mirror turns to the left side.




b. Reverse the polarity, and check that the mirror turns downward.

If operation is not as specified, replace the mirror assembly.




c. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the mirror turns upward.




d. Reverse the polarity, and check that the mirror turns downward.

If operation is not as specified, replace the mirror assembly.




10. W/ Driving position memory:
INSPECT MIRROR POSITION SENSORS OPERATION

HINT: Strip off the vinyl tape of the connector and remove terminals 2, 3, 6, 7 and 9 from the connector housing.

a. Connect a series of three 1.5 V dry cell batteries.
b. Connect the positive (+) lead from the dry cell batteries to terminal 7 and the negative (-) lead to terminal 6.
c. Connect the positive (+) lead from the voltmeter to terminal 9 and the negative (-) lead to terminal 6.







d. Apply Battery voltage to terminals 2 and 3, then check that the voltage gradually changes according to the table while the mirror moves between the uppermost position and lowermost position.

If voltage value is not as specified, replace the motor assembly.




e. Disconnect the 4 leads of the battery and voltmeter.
f. Connect the positive (+) lead from the voltmeter to terminal 8 and negative (-) lead to terminal 6.







g. Apply Battery voltage to terminals 2 and 1, then inspect that the voltage gradually changes according to the table while the mirror moves between the left-most position and right-most position.

If voltage value is not as specified, replace the motor assembly.







11. INSPECT DRIVING POSITION MEMORY AND RETURN SWITCH CONTINUITY

If continuity is not as specified, replace the switch.
