PINPOINT TEST L: ONE TURN SIGNAL LAMP IS INOPERATIVE/ALWAYS ON

Test L1-L5:

Test L5-L7:

Test L7-L8:

Test L8-L9:

Normal Operation
When the multifunction switch is placed in the LH or RH turn positions, the voltage signal sent by the SJB is routed to circuit 2068 (BK/LB). With the multifunction switch in the LH or RH turn positions, the SJB controls the supply voltage to the respective turn lamps which then flash approximately 80 times per minute. The LH front turn lamp is supplied voltage from circuit 1342 (GY/BK). The RH front turn lamp is supplied voltage from circuit 1341 (DB/OG). The LH rear turn lamp is supplied voltage from circuit 1363 (WH/RD). The RH rear turn lamp is supplied voltage from circuit 1365 (GY/LB). The LH signal mirror is supplied voltage from circuit 1546 (PK). The RH signal mirror is supplied voltage from circuit 1547 (RD). Ground for the LH front turn lamp is supplied through circuit 1205 (BK) from the BEC. Ground for the other turn lamps is supplied through circuit 1205 (BK).

Possible Causes
- circuit 1205 (BK) open
- circuit 1341 (DB/OG) open, short to power or short to ground
- circuit 1342 (GY/BK) open, short to power or short to ground
- circuit 1363 (WH/RD) open, short to power or short to ground
- circuit 1365 (GY/LB) open, short to power or short to ground
- circuit 1546 (PK) open, short to power or short to ground
- circuit 1547 (RD) open, short to power or short to ground
- signal mirror (if equipped)
- BEC
- SJB
