NOTE:
The TCS control unit has three memory registers. When a problem occurs, the control unit stores the problem code
l
in the first memory register. If another problem occurs, or the same problem occurs again, the control unit moves
the first problem code to the next memory register and stores the second problem code in the first register. If there's
a third problem occurrence, the two existing problem codes are moved up one register and the third problem code
is stored in the first register. If problems continue to occur, the oldest problem code is moved out of the last register
and lost, and the most recent problem code is stored in the first register.
l 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 problem code stored in the control unit's memory.
