DTC B3794 08
- Cruise Control Function Request Circuit Signal Invalid
DTC B3794 61
- Cruise Control Function Request Circuit Actuator Stuck
Diagnostic Fault Information
Circuit/System Description
The cruise control switch is an input to the body control module (BCM). The BCM monitors the cruise control set/coast and resume/accelerate
switch signal circuit in order to detect when the driver has requested to perform a cruise control function. The BCM detects a specific voltage signal
on the cruise control switch signal circuit when a switch is applied. The BCM sends a serial data message to the engine control module (ECM),
indicating the status of the cruise control switches.
Conditions for Running the DTC
* The ignition is ON.
* The cruise switch is ON.
Conditions for Setting the DTC
B3794 08
The BCM detects an invalid voltage signal on the cruise control switch signal circuit is present for 0.5 second.
B3794 61
Stuck switch for either Resume/Accel or Set/Coast button for 60 seconds.
Actions Taken When the DTC Sets
* The malfunction indicator lamp (MIL) will not illuminate.
* The cruise control system is disabled.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear after 40 malfunction-free ignition cycles have occurred.

DTC B257A 00
- Headlamp Switch Input Signals Mismatch
Diagnostic Fault Information
Circuit/System Description
When the headlamp and panel dimmer switch is placed in the AUTO position, the body control module (BCM) receives a ground signal through
the headlamp switch headlamps OFF signal circuit. The headlamp and panel dimmer switch headlamps ON signal circuit and the park lamp switch
signal circuit are both open and have no ground signal. When the headlamp and panel dimmer switch is placed in the PARK or HEAD position, the
BCM will receive a ground signal through the headlamp switch headlamps ON signal circuit and the park lamp switch signal circuit. The headlamp
switch headlamps OFF signal circuit will be open and have no ground signal.
Conditions for Running the DTC
Battery voltage must be between 9-16 V
Conditions for Setting the DTC
The BCM detects a short to ground on the headlamp switch headlamps OFF signal circuit or the headlamp switch headlamps ON signal circuit.
