The Powertrain Control Module (PCM) has been programmed to monitor the following cooling system components:
If the problem is sensed in a monitored circuit often enough to indicate an actual problem, a DTC is stored. The DTC will be stored in the PCM memory for eventual display to the service technician.
To read DTC's and to obtain cooling system data, (Refer to 25 - EMISSIONS CONTROL/ON-BOARD DIAGNOSTICS - OPERATION).
