Component Inspection
- Check A/C relay
- IG "OFF" and disconnect A/C relay
- Measure resistance between battery power supply and power supply to A/C Compressor terminals of A/C relay. (Measurement "A")
- Measure resistance between battery power supply and A/C relay control terminals of A/C relay. (Measurement "B")
Specification :
CONTINUITY SPECIFICATIONTerminal Continuity Battery power supply - Power supply to A/C Compressor NO Battery power supply - A/C 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 A/C relay and check for proper operation. If the problem is corrected, replace A/C relay and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
