INSPECTION

PROCEDURE

1. INSPECT MAP LIGHT SUB-ASSEMBLY (for TMC Made)

(a) Resistance Check

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

Standard Resistance:

Tester Connection

Condition

Specified Condition

2 (RLMP) - 1 (DOOR)

Door linked switch on

Below 1 Ω

2 (RLMP) - 11 (GND)

Dome light switch on

Below 1 Ω

If the result is not as specified, replace the map light sub-assembly.

*a

Component without harness connected

(Map Light Sub-assembly)

(b) Illumination Inspection

(1) Apply battery voltage to the map light sub-assembly and check that the lights illuminate.

OK:

Measurement Condition

Condition

Specified Condition

Battery positive (+) → 10 (+B1)
