Pinpoint Test A: All Power Windows are Inoperative

Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number

Normal Operation

Under normal operation, the LH front power window control switch receives power from the accessory delay relay through circuit CBB38 (GY/BU) to provide up/down commands to all the window motors and passenger window control switches when the LH front window control switch is in the UNLOCK position.

This pinpoint test is intended to diagnose the following:

- Fuse(s)

- Accessory delay relay

- Wiring, terminals or connectors

- LH front window control switch

- Smart Junction Box (SJB)

PINPOINT TEST A : ALL POWER WINDOWS ARE INOPERATIVE

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

A1 CHECK CIRCUIT CBB38 (GY/BU) FOR VOLTAGE

- Disconnect: LH Front Window Control Switch C504.

- Ignition ON.

- Measure the voltage between LH front window control switch C504-3, circuit CBB38 (GY/BU), harness side and ground.





Is the voltage greater than 10 volts?

Yes
INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.

No
VERIFY SJB (Smart Junction Box) fuse 41 (15A) and Battery Junction Box (BJB) fuse 38 (5A) are OK. If OK, GO to Pinpoint Test L to diagnose the accessory delay relay. Pinpoint Test L: The Delayed Accessory is Inoperative

If not OK, Refer to the Wiring Diagrams to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation. Diagrams By Number
