For a complete wiring diagram Refer to Section 8W.
- When Monitored:
With the ignition on.
- Set Condition:
If the Totally Integrated Power Module (TIPM) detects a short to ground on the (C7) Blower Motor Control circuit, when blower motor operation is requested.
| Possible Causes |
| (C7) BLOWER MOTOR CONTROL CIRCUIT SHORTED TO GROUND |
| BLOWER MOTOR |
| TOTALLY INTEGRATED POWER MODULE (TIPM) |
Diagnostic Test
1. VERIFY DTC IS ACTIVETurn the blower control switch to off.
Turn the ignition off, wait 10 seconds, and turn the ignition on.
With the scan tool, erase DTCs.
Turn the ignition off, wait 10 seconds, and turn the ignition on.
Turn the blower control switch to on.
With the scan tool, read DTCs.
Does the scan tool display active: B10E9–BLOWER MOTOR CONTROL CIRCUIT LOW?
Yes

No
- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
2. CHECK FOR ACTIVE DTC B10E9–BLOWER MOTOR CONTROL CIRCUIT LOW WITH BLOWER MOTOR HARNESS CONNECTOR DISCONNECTED
Turn the blower control switch to off.
Disconnect the Blower Motor harness connector.
Turn the ignition off, wait 10 seconds, and turn the ignition on.
With the scan tool, erase DTCs.
Turn the ignition off, wait 10 seconds, and turn the ignition on.
Turn the blower control switch to on.
With the scan tool, read DTCs.
