NOTE:
• The TCS control unit has three memory registers. When a problem occurs, the control unit stores the Diagnostic
Trouble Code (DTC) in the first memory register. If another problem occurs, or the same problem occurs again, the con-
trol 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 code are moved up one register and the third code is stored in the first reg-
ister. 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.
• The TCS indicator light will not come on again after the engine starts unless another problem occurrence is detected.
However, there will still be a code stored in the control unit's memory.
• After the repair is completed, disconnect the SCS service connector from the Service Check connector, and remove the
CLOCK (7.5 A) fuse from the under-hood fuse/relay box for at least three seconds to erase the control unit's memory.
• The control unit's memory is erased if the connector is disconnected from the control unit or if the control unit is
removed from the car.
