PROCEDURE

1. INSPECT OUTER MIRROR LH

(a) Check the outer mirror heater operation.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

1 - 2

25°C (77°F)

6.8 to 10.2 Ω

If the result is not as specified, replace the outer mirror LH.

*a

Component without harness connected

(Outer Mirror LH)

(b) w/ EC Mirror:

Check EC mirror operation.

(1) Connect a new 1.5 V dry-cell battery.

(2) Apply 1.5 V dry-cell battery voltage to the terminals of the connector, and check that the EC mirror operation.

NOTICE:

Do not apply a voltage of higher than 1.5 V.

OK:
