Component Inspection
- Check Main Relay
- IG "OFF"
- Disconnect Main Relay
- Measure the resistance between terminal 30 and 87 of main relay.
- Measure the resistance between terminal 85 and 86 of main relay.
SPECIFICATION:
TERMINAL CONTINUITY CHARTTerminal continuity 30-87 NO 85-86 YES (Approx. 70Ω-120Ω) - Is the measured resistance within specification?
YES
- Substitute with a known-good ECM and check for proper operation.
If the problem is corrected, replace ECM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM.NO
