ON-VEHICLE INSPECTION
PROCEDURE
1. 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
|
Battery voltage not applied between terminals 1 and 2
|
10 kΩ or higher
|
Battery voltage 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).
|
|
2. 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.
Standard Resistance:
Tester Connection
|
Condition
|
Specified Condition
|
3 - 5
|
Battery voltage not applied between terminals 1 and 2
|
10 kΩ or higher
|
Battery voltage 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).
|
|
3. 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.
