Control Circuit Inspection
WARNING: This page is about a different variant/trim than selected.
■ Check for Short to Ground in Control harness
- IG "OFF" and Disconnect the Injector and PCM connectors.
- Measure the resistance between the Highside terminal of Injector harness connector and chassis ground.
- Measure the resistance between the Lowside terminal of Injector harness connector and chassis ground.
Specification: Infinite
- Is the measured resistance within specification?
YES
- Go to next procedure below.
NO
- Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
■ Check short to battery in harness
- IG "OFF". Disconnect Injector connector.
- IG "ON".
- Measure the voltage between the Highside terminal of Injector harness connector and chassis ground.
- Measure the voltage between the Lowside terminal of Injector harness connector and chassis ground.
Specification: Approx. 0 Ω
- Is the measured voltage within specification?
YES
- Go to "COMPONENT INSPECTION " procedure.
NO
- Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
