INSPECTION

PROCEDURE

1. INSPECT ROOF CONSOLE BOX SUB-ASSEMBLY (for Normal Roof)

(a) Apply auxiliary battery voltage to the roof console box sub-assembly and check that the lights illuminate.

OK:

Map Light LH and Map Light RH

Measurement Condition

Condition

Specified Condition

Auxiliary battery positive (+) → 10 (+B1)

Auxiliary battery negative (-) → 11 (GND)

Dome light switch off and map light switch LH on

Map light LH illuminates
