CAUTION:

NOTE:

When the engine coolant temperature is below 0 °C {32 °F}, the TCS OFF light stays on until the engine warms up to the normal operating temperature (max. approx. 15 min.). If the light goes off after warming up, the system is normal.
The TCS OFF light illuminates at key on engine off. Start engine and inspect again.
If any symptoms have occurred in the past but are now okay, malfunction of related harness could be the possible cause and thus ABS CM is normal.
