For a complete wiring diagram, refer to the Wiring Information.
When Monitored:
With the ignition on.
Set Condition:
If during blower motor operation, the Totally Integrated Power Module (TIPM) detects an over-current condition on the (C7) Blower Motor Supply circuit for more than 500 msec.
Possible Causes
BLOCKAGE STALLING BLOWER MOTOR
(C7) BLOWER MOTOR SUPPLY CIRCUIT SHORTED TO GROUND
BLOWER MOTOR
TOTALLY INTEGRATED POWER MODULE (TIPM)
1.
VERIFY THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE
1.
Turn the ignition off.
2.
Turn the Blower Motor controls to the off position.
3.
Ignition on, engine not running.
4.
With the scan tool, read and record TIPM DTCs.
NOTE:
Record the Environmental Data for all DTCs before erasing. The Environmental Data can help in duplicating the conditions in which the DTC originally set.
5.
With the scan tool, erase TIPM DTCs.
6.
Turn the Blower Motor controls to high.
NOTE:
It might take a few minutes of blower motor operation to reset this DTC.
Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
Inspect the Blower Motor Housing for debris or an obstruction that may inhibit the blower motor wheel cage from rotating freely. Clean and repair as necessary. If no problems are found, replace the Blower Motor in accordance with the Service Information.
