INSPECTION
PROCEDURE
1. INSPECT MAP LIGHT ASSEMBLY
(a) Check the map light.
| (1) Apply auxiliary battery voltage to the map light assembly and check that the map light comes on. OK: | Tester Connection | Switch Condition | Specified Condition | | V7-1 (+B1) - Auxiliary battery positive (+) V7-4 (GND) - Auxiliary battery negative (-) | Map light switch LH on | Map light LH comes on | | V7-1 (+B1) - Auxiliary battery positive (+) V7-4 (GND) - Auxiliary battery negative (-) | Map light switch LH off | Map light LH does not come on | | V7-1 (+B1) - Auxiliary battery positive (+) V7-4 (GND) - Auxiliary battery negative (-) | Map light switch RH on | Map light RH comes on | | V7-1 (+B1) - Auxiliary battery positive (+) V7-4 (GND) - Auxiliary battery negative (-) | Map light switch RH off | Map light RH does not come on | | V7-1 (+B1) - Auxiliary battery positive (+) V7-4 (GND) - Auxiliary battery negative (-) | Map light switch off and door switch on | Map light comes on | | V7-1 (+B1) - Auxiliary battery positive (+) V7-4 (GND) - Auxiliary battery negative (-) | Map light switch off and door switch off | Map light does not come on | If the result is not as specified, replace the map light assembly. |

(b) Check the door switch.
| (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Switch Condition | Specified Condition | | V7-2 (DOOR) - V7-9 (RLMP) | Door switch on | Below 1 Ω | | V7-2 (DOOR) - V7-9 (RLMP) | Door switch off | 10 kΩ or higher | If the result is not as specified, replace the map light assembly. | |
