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
|
Auxiliary battery voltage is not applied between terminals 1 and 2
|
10 kΩ or higher
|
Auxiliary battery voltage is applied between terminals 1 and 2
|
Below 1 Ω
|
If the result is not as specified, replace the circuit opening relay assembly (C/OPN).
