PINPOINT TESTS PINPOINT TEST Z: ONE OR BOTH REVERSING LAMPS ARE INOPERATIVE

Z1-Z2:

Z2-Z3:

Normal Operation
Under normal operation, when the PCM detects the transmission is in REVERSE, a signal is sent to the SJB over the communication network. The SJB then sends voltage to the reversing lamps through circuit 1367 (WH/YE). Ground for the lamps is provided through 1205 (BK).

Possible Causes
- An open in circuit 1367 (WH/YE)
- Lamp
- Smart junction box (SJB)
