Component Inspection
- Check Main relay
- IG "OFF" and disconnect main relay.
- Measure the resistance between battery power supply and control terminals of main relay. (Measurement "A")
- Measure the resistance between battery power supply and power supply to PCM terminals of main relay. (Measurement "B")
Specification :
CONTINUITY SPECIFICATIONTerminal Continuity Battery power supply - Power supply to PCM NO Battery power supply - Main relay control YES (Approx. 70Ω~120Ω) - Is the measured resistance within specification?
YES
- Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.NOTE: There is a memory reset function on GDS that can erase optional parts automatically detected and memorized by PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
NO
- Substitute with a known - good Fuel Pump Relay and check for proper operation. If the problem is corrected, replace Fuel Pump Relay and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
