COOLING SYSTEM RELATED DIAGNOSTICS
The powertrain control module (PCM) has been programmed to monitor certain cooling system components:
If the problem is sensed in a monitored circuit often enough to indicated an actual problem, a DTC is stored. The DTC will be stored in the PCM memory for eventual display to the service technician.
Refer to Group 25, Emission Control Systems for the correct procedures.
ACCESSING DIAGNOSTIC TROUBLE CODES
To read DTC's and to obtain cooling system data, refer to Group 25, Emission Control Systems for the correct procedures.
ERASING TROUBLE CODES
After the problem has been repaired, use the DRB scan tool to erase a DTC. Refer to the appropriate Powertrain Diagnostic Procedures service manual for operation of the DRB scan tool.
DRB SCAN TOOL
For operation of the DRB scan tool, refer to the appropriate Powertrain Diagnostic Procedures service manual.
