Pinpoint Test M: The Turn Signal Lamps Are Always On

Refer to Wiring Diagram Set 90, Turn Signal/Stop/Hazard Lamps for schematic and connector information. Diagrams By Number

Normal Operation

The Smart Junction Box (SJB) sends reference signals to the multifunction switch through circuits CLS39 (VT/WH) (LH turn input) and CLS41 (GY/YE) (RH turn input). When the multifunction switch is switched to the LH or RH TURN positions, the voltage signal is routed to ground. When the SJB detects the multifunction switch in the LH or RH TURN position, the SJB sends voltage to the appropriate turn lamps.

- DTC B2281 (Right Turn Switch Short to Ground) - an on-demand DTC that sets when the SJB detects a short to ground from the RH turn signal input circuit.
- DTC B2282 (Left Turn Switch Short to Ground) - an on-demand DTC that sets when the SJB detects a short to ground from the LH turn signal switch input circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Multifunction switch
- SJB



PINPOINT TEST M: THE TURN SIGNAL LAMPS ARE ALWAYS ON

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