Component Inspection

1. Ignition "OFF".
2. Disconnect TCS/ESC switch connector.
3. Press the TCS/ESC switch.
4. Measure resistance between terminal "4" of the TCS/ESC switch harness connector and terminal "5" of the TCS/ESC switch harness connector.
A. Specification : Approx. below 1 Ohm - ESC switch is depressed.

Approx. Infinity Ohms - ESC switch is not depressed.




5. Is the measured resistance within specifications?
YES
1) Fault is intermittent caused by faulty TCS/ESC switch or was repaired and HECU memory was not cleared. Go to "Verification of Vehicle Repair" procedure.
NO
1) Substitute with a known-good TCS/ESC switch and check for proper operation. If problem is corrected, replace TCS/ESC switch and then go to "Verification of Vehicle Repair" procedure.
