Multiplex Control System
Troubleshooting (cont'd)
Made 2 Tes!
1. From Mode 1, disconnect the special tool from the
multiplex inspection connector for 5 to 10 seconds,
and then reconnect
it.
2. The spotlight and ceiling light should come on for 2
seconds, go out, then blink twice, 0.2 seconds each
time. The system is now in mode 2.
3. Operate the switches listed below: If the circuit is
ok, the spotlight and ceiling light will blink once. If
the circuit is faulty, the lights will not blink.
Tip: Operate the switches most closely related
to the problem you are diagnosing is a quick way
of testing the circuits integrity.

failed at the same time in mode 2, go to the
multiplex sleep mode test. If a single switch fails in
mode 2, troubleshoot its circuit.
