ESC Switch Check
- Ignition "ON" & Engine "OFF".
- Disconnect the ESC switch connector.
- Measure resistance between power terminal and signal terminal of the ESC switch connector.
Specification : Approx. below 1Ω (In case of pressing the ESC switch)
Approx. ∞ Ω (In case of not pressing the ESC switch)
- Is the measured value within specifications?
YES:
- Fault is intermittent caused by poor connection in ESC switch harness and/or HECU's connector.
Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO:
- Substitute with a known-good ESC switch and check for proper operation.
If problem is corrected, replace ESC switch and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
