Supersession Statement
This PI was superseded to add model years and update notes in Step #4. Please discard PIT4844H.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition / Concern
Some customers may request the installation of Cruise Control on a vehicle which did not
come equipped with the option.
General Motors requests that dealers locate a vehicle equipped with the customers
requested options, which would include cruise control.

Recommendations / Instructions
Please contact the Techline Customer Support Center (TCSC) at 1-800-828-6860

English

or 1-800-503- 3222 French to determine if a calibration is available for the vehicle. If a
calibration or VCI is available, follow the instructions below:
Obtain and install the following parts that are intended for a vehicle equipped with RPO K34.
1. Steering Wheel with Cruise Control Buttons
2. Steering Wheel SIR Coil Note: *(If required, some Vans may have the uplevel Steering
Wheel SIR Coil installed from the factory. The dealer will just need to document that the
correct SIR Coil is already installed in the vehicle on the Repair Order when sending to
Techline.)
3. Steering Column Wiring Harness Note: *(If required, some Vans may have the uplevel
Steering Column Wiring Harness installed from the factory. The dealer will just need to
document that the correct harness is already installed in the vehicle on the Repair Order
when sending to Techline.)
4. Calibration or VCI number from Techline Customer Support
Note: The Dealer will need to Fax a copy of the Repair Order that includes the Part Numbers
of the Steering Wheel with buttons, SIR Coil, and Steering Column Harness that were
installed to Techline before calling to obtain the VCI Number. (Some Vans may have the uplevel
Steering Wheel SIR Coil and Steering Column Wiring Harness installed from the factory. The dealer will need to
document that the correct P/N Steering Wheel SIR Coil and Steering Column Wiring Harness is already installed in
the vehicle on the Repair Order when sending to Techline.)

NOTE: As this is a customer pay request, there will be a charge to the dealer. When the
dealer contacts Techline they will be informed how much the fee for this request is.
Note: It is up to the dealer to identify the appropriate part numbers needed to complete this
add on option using the Electronic Parts Catalog (EPC). Be sure to turn off all filters when
searching EPC and identify the following items above that include RPO K34.
Note: DO NOT call Partech for parts assistance for this request.

Warranty Information
This installation procedure is to be performed at the customer's request and at their
expense.
It is not a warranty repair and a claim should not be submitted for reimbursement.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.
