Traction Control System (TCS) Operation Check

NOTE: With ignition switch turned to ON position, TCS will operate unless manually deactivated by depressing TCS OFF switch.
NOTE: If front wheels have been rotating for 60 seconds or more while rear wheels have been stationary, ABS warning light, TCS indicator light and TCS OFF lights may illuminate and engine speed may increase. Cycle ignition switch to OFF and then to ON position, then drive vehicle at more than 12 MPH. Indicator lights should turn off and ABS/TCS related DTCs should not be present.
  1. Perform operation check to determine if TCS is functioning properly. Place front wheels on a chassis roller or raise and support front of vehicle. Start engine. Ensure TCS OFF indicator light is not illuminated.
    2. NOTE: If engine coolant temperature is extremely low, TCS control is temporarily interrupted until engine coolant temperature increases. If this occurs, TCS OFF indicator light will illuminate.
  2. If TCS OFF indicator light and TCS warning light remain illuminated after engine is started, system has detected a failure. Turn ignition switch to OFF position. Check for ABS/TCS related Diagnostic Trouble Codes (DTCs). See RETRIEVING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. Perform appropriate diagnostic test(s). See DIAGNOSTIC TESTS . If TCS OFF indicator light and TCS warning light are not illuminated, go to next step.
  3. Place transaxle shift lever in Drive. Depress accelerator for about 5 seconds. Engine speed should be held at low RPM and TCS warning light should flash indicating TCS is regulating engine torque. If TCS functions as specified, system is functioning properly at this time. If TCS does not function as specified, perform appropriate trouble shooting procedure.
