Pinpoint Test 1

PINPOINT TEST 1: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Normal Operation
The smart junction box (SJB) sends reference signals to the multi-function switch through circuit (BR/L) (LH turn input) and circuit (BR/W) (RH turn input). When the multi-function switch is switched to the LH or RH TURN positions, the voltage signal is routed to ground. When the SJB detects the multi-function switch in the LH or RH TURN position, the SJB sends voltage to the appropriate turn lamps.

Possible Causes
- Wiring, terminals or connectors
- Multi-function switch
- SJB

Diagnostic Procedure

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