1.INSPECT MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
Check the resistance.
| *a | Component without harness connected
(Multiplex Network Master Switch Assembly) |
Measure the resistance according to the value(s) in the table below.
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| L7-20 (UP) - L7-12 (GND) | Up position | Below 100 Ω |
| L7-15 (DOWN) - L7-12 (GND) | Down position | Below 100 Ω |
If the result is not as specified, replace the multiplex network master switch assembly.
Check that the LED illuminate.
| *a | LED |
| *b | Component without harness connected
(Multiplex Network Master Switch Assembly) |
Apply auxiliary battery voltage to the multiplex network master switch assembly and check that the LED illuminates.
| Auxiliary Battery Connection | Specified Condition |
|---|---|
| L7-3 (ILL+) - Auxiliary battery positive (+)
L7-13 (ILL-) - Auxiliary battery positive (-) |
LED illuminates |
If the result is not as specified, replace the multiplex network master switch assembly.
