SET - (pressed/released)	On/Off
GAP + (pressed/released)	On/Off
GAP - (pressed/released)	On/Off

Does the PID value agree with the switch position?

Yes	If equipped with 6.2L or 6.8L, GO to A4 If equipped with 6.7L diesel, GO to A5

No	If only one switch does not display the correct PID value, INSTALL a new LH steering wheel switch. REFER to: Steering Wheel Multifunction Switch . If multiple switches do not display the correct PID value, GO to A6

A4 MONITOR THE PCM (POWERTRAIN CONTROL MODULE) TR (TRANSMISSION RANGE) PID
- Using a diagnostic scan tool, view PCM Parameter Identifications (PIDs).
- Monitor the PCM TRPID.
- Place the shift selector in DRIVE.
Does the PID value agree with the TR selector lever position?

Yes GO to A11

No REFER to: External Controls .

A5 MONITOR THE TCM (TRANSMISSION CONTROL MODULE) PID
- Using a diagnostic scan tool, view TCM Parameter Identifications (PIDs).
- Monitor the TCM PIDTR.
- Place the shift selector in DRIVE.
Does the PID value agree with the selector lever position?

Yes GO to A12

No REFER to: External Controls .

A6 CHECK THE CRUISE CONTROL SWITCH FOR VOLTAGE

Ignition OFF.

Remove the driver airbag. REFER to: Driver Airbag .

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
