ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT CIRCUIT OPENING RELAY ASSEMBLY (C/OPN)
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
3 - 5 |
Battery voltage not applied to terminals 1 and 2 |
10 kΩ or higher |
|
Battery voltage applied to terminals 1 and 2 |
Below 1 Ω |
If the result is not as specified, replace the circuit opening relay assembly (C/OPN).
