Circuit Description

Ignition voltage is supplied directly to the cooling fan relay coil. The ECM controls the relay by grounding the
control circuit. When the ECM is commanding a command ON, the voltage of the control circuit should be low
(near 0 volt).

When the ECM is commanding the control circuit should be high (near battery voltage). If the fault detection circuit
senses a voltage other than what is expected, the fault line status will change causing the fault code to set.

Circuit Description

When the ECM detects that A/C has been requested, the ECM will activated the A/C clutch relay. When the relay
has been activated, voltage should be present at both the A/C clutch relay and A/C switch circuit at ECM.

Circuit Description

Battery voltage is supplied to the TCS warning lamp with the ignition in ON and START. The warning lamp can be
activated only by the Electrical Brake Control Module (EBCM) internally supplying ground to terminal 21. If the
TCS input circuit is open or short, this failure code will be set.
