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).
|
|
2. INSPECT NO. 1 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO.1)
(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 No. 1 electronic fuel injection main relay (EFI-MAIN NO.1).
|
|
3. INSPECT NO. 2 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO.2)
(a) Measure the resistance according to the value(s) in the table below.

Auxiliary battery voltage is applied between terminals 1 and 2
|
Below 1 Ω
|
If the result is not as specified, replace the No. 2 electronic fuel injection main relay (EFI-MAIN NO.2).
4. INSPECT NO. 3 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO.3)
(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
