• Set Condition: If the totally integrated power module detects an excessive current draw on the blower motor supply circuit when blower motor operation is requested.






Test Step 1 - Verify DTC is Active

• Turn the blower control switch to OFF.

• Turn the ignition OFF, wait 10 seconds, and turn the ignition ON.

• With the scan tool, erase TIPM DTCs.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 2 - Test the Blower Motor Supply Circuit for a Short to Ground

• Turn the ignition OFF.

• Disconnect the TIPM C harness connector.

• Measure the resistance between ground and the blower motor supply circuit in the TIPM harness connector.

Is the resistance less than 10k ohms?

Yes

• Repair the blower motor supply circuit for a short to ground.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

No

• Replace the TIPM.
