I’m having so much trouble trying to change the ignition housing on my SUV. Someone tried to steal it last night so I’m not sure if it caused more damage or what because every video I’ve watched mine is not so simple. Please someone help me give instructions on what to do. I’ve been at this all day and just want some help to finally finish. I’m a single mom and missed work today so I need help. Please

Good morning,

Can you upload some pictures of where you are in the repair?

In most cases, it is easier to replace the column than repair it.

I attached the procedure for you to view. The only thing that will need to be done is to program the key to the car.

You can go to www.car-part.com and see the yards in your area that have the column for you.

Tools Required
J 42640 Steering Column Lock Pin

Removal Procedure

Notice: Once the steering column is removed from the vehicle, the column is extremely susceptible to damage. Dropping the column assembly on its end could collapse the steering shaft or loosen the plastic injections that maintain column rigidity. Leaning on the column assembly could cause the jacket to bend or deform. Any of the above damage could impair the columns collapsible design. If it is necessary to remove the steering wheel, refer to Steering Wheel. Under no condition should the end of the shaft be hammered on, as hammering could loosen the plastic injections which maintain column rigidity.

Notice: The front wheels of the vehicle must be maintained in the straight ahead position and the steering column must be in the LOCK position before disconnecting the steering column or intermediate shaft. Failure to follow these procedures will cause improper alignment of some components during installation and result in damage to the SIR coil assembly.

Caution: Refer to SIR Caution in Service Precautions.

1. Disable the Supplemental Inflatable Restraint (SIR) system. Refer to Disabling the SIR System in Restraint Systems.
2. Remove the knee bolster. Refer to Knee Bolster Replacement in Instrument Panel, Gauges and Warning Indicators.
3. Lock the steering column through the access hole in the lower steering column trim cover using the J 42640.

4. Remove the body control module bracket. Do not disconnect the harness from the body control module. Refer to Body Control Module Replacement in Powertrain Management.
5. Disconnect the transmission shift cable (1) from the steering column.

6. Disconnect the steering column electrical connectors.

Notice: During removal of the steering column the wire harness retaining clip must be removed and reinstalled after installing the steering column or damage may occur to the wire harness.

7. Remove the electrical harness retaining pin (4) from the instrument panel.

8. Remove the upper intermediate shaft pinch bolt (1) from the steering column to remove the intermediate shaft (2).

10. Remove the nuts from the upper support bracket.
11. Remove the steering column from the vehicle.

Key Programming

PROGRAMMING REPLACEMENT PASSLOCK(TM) SENSOR, BCM, OR PCM

IMPORTANT:
The Body Control Module (BCM) must be programmed with the proper PRO configurations before performing learn procedures. See BCM Programming/RPO Configuration.
If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn Passlock(TM) sensor data code immediately. The existing PCM however, must learn the new fuel continue password when the BCM is replaced.
If replacing a PCM with a GM Service Parts Operations (SPO) replacement part, after programming, these modules will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password and will require a learn procedure after programming to learn the current vehicle's password.

CONDITIONS
Use this procedure after replacing:
Passlock(TM) Sensor
BCM
PCM

LEARN PROCEDURES
There are two available methods to perform the programming procedure:
A 10 minutes procedure which requires a Tech 2 and a techline terminal.
A 30 minutes procedure which does not require the use of any tools.

10 MINUTE LEARN PROCEDURE

TOOLS REQUIRED
Tech 2
Techline terminal with current Service Programming System (SPS) software

1. Connect the Tech 2 to the vehicle.
2. Select "Request Information" under "Service Programming".
3. Disconnect the Tech 2 from the vehicle and connect it to a techline terminal.
4. On the techline terminal, select "Theft Module Re-Learn" under "Service Programming".
5. Disconnect the Tech 2 from the techline terminal and connect it to the vehicle.
6. Turn ON the ignition, with the engine OFF.
7. Select "VTD Re-Learn" under "Service Programming".
8. Attempt to start the engine, then release the key to ON (vehicle will not start).
9. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF (the vehicle is now ready to relearn the Passlock(TM) Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK).
10. Turn OFF the ignition, and wait 5 seconds.
11. Start the engine (the vehicle has now learned the password).
12. With the Tech 2 (scan tool), clear any DTCs.

30 MINUTE LEARN PROCEDURE
1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds.
5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the Passlock(TM) Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).

IMPORTANT: The vehicle learns the Passlock(TM) Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

6. Start the engine. The vehicle has now learned the Passlock(TM) Sensor Data Code and/or password.
7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.
