瀚慖f less than the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace
the BCM.
4. Ignition OFF, disconnect the X1 harness connector at the BCM.
5. Test for infinite resistance between the signal circuit terminal 3 and ground.
瀚慖f less than the specified value, test the signal circuit for a short to ground.
6. If all circuits test normal, test or replace the steering wheel control switch - left.
Component Testing
Steering Wheel Control Switch - Left
1. Disconnect the harness connector at the steering wheel controls switch - left.
2. Cruise control switch ON, measure the resistance between terminal 1 and terminal 3 while individually activating and holding each cruise
control function switch and compare the resistance reading to the values in the table below.
瀚慖f not within the specified resistance range, replace the steering wheel controls switch - left.

Diagnostic Fault Information
Circuit/System Description
The TCC Brake signal circuit is a high voltage input to the body control module (BCM), engine control module (ECM), transmission control
module (TCM), Power Take Off (PTO) module (if equipped) and Trailer Brake controller (if equipped). The BCM monitors the stop lamp switch
circuit to detect when the brake pedal has been applied. The ECM monitors the TCC Brake signal to determine when the brake pedal is applied.
