Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) monitors the cruise control indicator switch. When the cruise on/off switch is pressed ON, the cruise control switch is
closed and the signal circuit is low. When the cruise on/off switch is pressed OFF, the cruise control switch is open and the signal circuit is high.

Circuit/System Testing
Important: Refer to DTC B3794 (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Diagnostic Trouble Code
Tests and Associated Procedures/B Code Charts/B3794) before performing this diagnostic, if this code is set as current or history.
1. Ignition OFF, disconnect the harness connector at the steering wheel controls switch-left.
2. Ignition ON, verify that a test lamp illuminates between the low reference circuit terminal 9 and B+.
‹› If the test lamp does not illuminate, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal,
replace the BCM.
3. If all circuits test normal, test or replace the steering wheel controls switch-left.
