Test L: The Turn Signal Lamps Are Always On

PINPOINT TEST L: THE TURN SIGNAL LAMPS ARE ALWAYS ON

Normal Operation
The 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 placed in 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 provides on/off voltage to the appropriate turn lamps.

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

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multifunction switch
- SJB
