Theory of Operation
The Tow/haul Overdrive OFF (control) Switch is located in the shift lever arm. The switch is a momentary contact
device that signals the PCM to toggle current status of the overdrive function. At ignition on, overdrive operation is
allowed. Pressing the Tow/Haul Overdrive Off switch once causes the Tow/haul Overdrive OFF mode to be entered
and the Tow/Haul lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to
be restored and the Tow/haul lamp to be turned off. The Tow/haul Overdrive OFF mode defaults to ON after the
ignition switch is cycled OFF and ON. Thenormal position for the control switch is the ON position. The switch must
be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the Tow/haul Overdrive Off switch is turned to the OFF position, or when illuminated by the transmission con-
trol module.
When Monitored:
The engine must have been running for at minimum of 10 seconds. The circuit is tested every 440ms.
Set Condition:
This DTC will set if the Tow/Haul Overdrive Off Switch Sense circuit is heldlow for 5 minutes or more from the
time of switch closure or ignition on with the engine running.
Possible Causes
TOW/HAUL OVERDRIVE OFF SWITCH SENSE CIRCUIT SHORT TO GROUND
TOW/HAUL OVERDRIVE OFF SWITCH
ENGINE CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)

1.TOW/HAUL OVERDRIVE OFF SWITCH SENSE CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the PCM C3 harness connector.
Disconnect the Tow/Haul OverdriveOff switch harness connector.
Measure the resistance between ground and the Tow/Haul Overdrive
Off switch sense circuit in the PCM C3 harness connector.
Is the resistance below 5.0 ohms?

Repair the Tow/Haul Overdrive Off switch sense circuit for a
short to ground.
