1. Stop the engine.2. Turn the ignition switch "ON", and confirm that the Traction Control System (TCS) indicator light comes on.
3. Turn the ignition switch off.
4. Connect the service connector to the service check connector located under the glove box.
5. Turn the ignition switch ON, but do not start the engine.
6. Record the blinking frequency of the TCS indicator light. The blinking frequency indicates the Diagnostic Trouble Code (DTC). Long blinks indicate the main code; short blinks indicate the sub-code.
NOTE: The TCS control unit has three memory registers. When a problem occurs, the control unit stores the DTC in the first memory register. If another problem occurs, or the same problem occurs again, the control unit moves the first code to the next memory register and stores the second code in the first register. If there's a third problem occurrence, the two existing codes are moved up one register and the third code is stored in the first register. If problems continue to occur, the oldest code is moved out of the last register and lost, and the most recent code is stored in the first register.
