When Monitored:
With the ignition on.
Set Condition:
If the Totally Integrated Power Module (TIPM) detects an excessive current draw on the (F942) Fused Ignition
Switch Output (Run-Start) circuit for 20 micro seconds when blower motor operation is requested.
Possible Causes
(F942) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO GROUND
BLOWER MOTOR
TIPM
Diagnostic Test
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.
Turn the ignition off, wait 10 seconds, and turn the ignition on.
Turn the blower control switch to on.
With the scan tool, read TIPM DTCs.
Does this DTC reset?
Ye s>>
Go To 2
No>>
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, corroded, and contam-
inated terminals.
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 TIPM 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 TIPM DTCs.
Does the scan tool display active: B10E9–BLOWER MOTOR
CONTROL CIRCUIT LOW?
Ye s>>
Go To 3
No>>
Replace the Blower Motor in accordance with the Service
Information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8
- ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).
