Pinpoint Test H: An Individual Demand Lamp Is Inoperative
Refer to Wiring Diagram Set 89, Interior Lamps for schematic and connector information Electrical Diagrams.
Normal Operation
When the battery saver relay is energized, voltage is supplied to the demand lamps.
This pinpoint test is intended to diagnose the following:

- Sun visor
- Interior lamp
PINPOINT TEST H : AN INDIVIDUAL DEMAND LAMP IS INOPERATIVE
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
H1 CHECK FOR VOLTAGE TO THE INOPERATIVE LAMP
- Disconnect: Inoperative Demand Lamp.
- Ignition ON.
- Measure the voltage between the inoperative demand lamp, harness side and ground as follows:
Inoperative Component Connector-Pin Circuit Front interior lamp (vehicles with roof opening panel) C931-2 CLN09 (YE/GN) Front interior lamp (vehicles without roof opening panel) C918-3 CLN09 (YE/GN) Second row interior lamp (vehicles with roof opening panel) C918-3 CLN09 (YE/GN) Cargo lamp C926A-1 CLN09 (YE/GN) LH vanity mirror lamp C907-1 CLN09 (YE/GN) RH vanity mirror lamp C906-1 CLN09 (YE/GN)
Is the voltage greater than 10 volts?
Yes
GO to H2.
No
REPAIR circuit CLN09 (YE/GN) for an open. TEST the system for normal operation.
H2 CHECK FOR VOLTAGE TO THE INOPERATIVE LAMP USING THE CONNECTOR GROUND
- Measure the voltage between the inoperative demand lamp connector, harness side as follows:
Inoperative Component Connector-Pin Circuit Front interior lamp (vehicles with roof opening panel) C931-2 CLN09 (YE/GN) C931-1 GD182 (BK/GY) Front interior lamp (vehicles without roof opening panel) C918-3 CLN09 (YE/GN) C918-2 GD182 (BK/GY) Second row interior lamp (vehicles with roof opening panel) C918-3 CLN09 (YE/GN) C918-2 GD182 (BK/GY) Cargo lamp C926A-1 CLN09 (YE/GN) C926B-1 GD182 (BK/GY) LH vanity mirror lamp C907-1 CLN09 (YE/GN) C907-2 GD182 (BK/GY) RH vanity mirror lamp C906-1 CLN09 (YE/GN) C906-2 GD182 (BK/GY)
Is the voltage greater than 10 volts?
Yes
INSTALL a new interior lamp in question. REFER to Interior Lamp . TEST the system for normal operation.
No
REPAIR circuit GD182 (BK/GY) for an open. TEST the system for normal operation.
