Circuit/System Verification

Engine ON, while rotating the steering wheel to both steering stops, observe the scan tool Cruise Control Switch parameter while pressing each of

the cruise control switches. The parameter should toggle between On, Off, Resume, Set, and Cancel as the applicable switch is pressed.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the S70L steering wheel control switch-left.

2. Ignition ON, test for B+ between the B+ circuit terminal 1 and ground.

瀚慖f less than the specified value, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9

BCM.

3. Test for B+ between the B+ circuit terminal 1 and the signal circuit terminal 2.

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 K9 BCM.

4. Ignition OFF, disconnect the X1 harness connector at the K9 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 S70L steering wheel control switch-left.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
