Pinpoint Test J: An Individual Demand Lamp Is Inoperative

Refer to Wiring Diagrams Set 89, Interior Lamps for schematic and connector information. Electrical Diagrams

Normal Operation

The Smart Junction Box (SJB) supplies voltage to the demand lamps.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Interior lamp

PINPOINT TEST J : 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.

J1 CHECK THE DEMAND LAMP OUTPUT CIRCUIT FOR AN OPEN

- Ignition OFF.

- Disconnect: Suspect Demand Lamp.

- Ignition ON.

- Measure the voltage between the suspect demand lamp, harness side and ground as follows:

Location Connector-Pin Circuit RH vanity mirror lamp C906-1 CLN09 (YE/GN) LH vanity mirror lamp C907-1 CLN09 (YE/GN) Front interior lamp C929-3 CLN09 (YE/GN) Second row interior lamp C961-3 CLN09 (YE/GN) Third row interior lamp C963-3 CLN09 (YE/GN) Second row LH lamp (grab handle) C9009-3 CLN09 (YE/GN) Second row RH lamp (grab handle) C9010-3 CLN09 (YE/GN)






Is the voltage greater than 10 volts?

Yes
GO to J2.

No
REPAIR the circuit in question for an open. TEST the system for normal operation.

J2 CHECK FOR VOLTAGE TO THE DEMAND LAMP USING THE CONNECTOR GROUND

- Measure the voltage between the suspect demand lamp, harness side as follows:

Location Connector-Pin/ Circuit Connector-Pin/ Circuit RH vanity mirror lamp C906-1 CLN09 (YE/GN) C906-2 GD133 (BK) LH vanity mirror lamp C907-1 CLN09 (YE/GN) C907-2 GD133 (BK) Front interior lamp C929-3 CLN09 (YE/GN) C929-1 GD133 (BK) Second row interior lamp C961-3 CLN09 (YE/GN) C961-2 GD133 (BK) Third row interior lamp C963-3CLN09 (YE/GN) C963-2 GD133 (BK) Second row LH lamp (grab handle) C9009-3 CLN09 (YE/GN) C9009-2 GD133 (BK) Second row RH lamp (grab handle) C9010-3 CLN09 (YE/GN) C9010-2 GD133 (BK)






Is the voltage greater than 10 volts?

Yes
For the LH or RH second row lamps, INSTALL a new interior lamp for the lamp in question. TEST the system for normal operation.

For all other interior lamps, INSTALL a new interior lamp for the lamp in question. REFER to Interior Lamp . TEST the system for normal operation.

No
REPAIR circuit GD133 (BK) for an open. TEST the system for normal operation.
