Pinpoint Test 6

PINPOINT TEST 6: ONE TURN SIGNAL/HAZARD LAMP IS ALWAYS ON

Step 1 - 2:

Normal Operation
The SJB sends reference signals to the multifunction switch through circuits (LB/R) (LH turn input) and (LG/O) (RH turn input). When the multifunction switch is switched to the LH or RH turn positions, the voltage signal is routed to ground through circuit (B/W). When SJB detects the multifunction switch is in the LH turn position, the SJB sends voltage through circuit (LG/W) to the LH turn lamps. When the SJB detects the multifunction switch is in the RH turn position, the SJB sends voltage through circuit (W/LB) to the RH turn lamps. Circuit (B) provides ground for each turn lamp.

All the turn lamps are individually wired to the SJB. The timed on/off cycle is determined in the SJB and is set to flash approximately 80 times per minute if both the front and rear turn lamps operate correctly. If Only one turn signal lamp operates, the SJB will flash approximately 160 times per minute.

Possible Causes
- circuit (W/LB) shorted to power
- circuit (LG/W) shorted to power
- hazard flasher switch
- SJB
