G10 CHECK THE MULTIFUNCTION SWITCH
-
Disconnect: Multifunction Switch.
-
Carry out the multifunction switch component test.
-
Is the multifunction switch OK?
Yes
REPAIR circuit CLS35 (VT) (LH rear stoplamp) or circuit CLS36 (YE) (RH rear stoplamp) for an open. TEST the system for normal operation.
No
INSTALL a new multifunction switch. TEST the system for normal operation.
-------------------------------------------------
G11 CHECK FOR CORRECT SJB OPERATION
-
Disconnect all the SJB connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the SJB connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new SJB. TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

Pinpoint Test H: The Stoplamps Are On Continuously
Refer to wiring Diagram Set 90, Turn Signal/Stop/Hazard Lamps for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Normal Operation
When the brake pedal is applied, the voltage is routed to the high mounted stoplamp and the multifunction switch through circuit CCB08 (VT/WH). The
multifunction switch then routes the voltage to the LH rear lamp through circuit CLS35 (VT) and the RH rear lamp through circuit CLS36 (YE). Voltage
to the LH and RH rear lamps also routes through the Battery Junction Box (BJB) fuse 42 (7.5A) to circuit CAT06 (YE) and fuse 38 (7.5A) to circuit
CAT09 (GN) for the trailer tow lamps.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
Stoplamp switch
-
Multifunction switch
