Condition/Concern: Some customers may comment that they are unable to override the automatic door locking feature. In prior model years, customers were able to select “Doors Lock Manually” from the DIC. However, starting in the 2005 model year, this selection was removed. Recommendation/Instructions: Since the 2005 model year, all BCM’s (Body Control Modules) are programmed from the factory to lock all doors when the transmission is shifted into gear or vehicle speed is greater than 8 mph (13 km/h). There is no option to disable the auto door locks from the factory,

Some customers may comment on a clunk, bump or squawk noise when the vehicle comes to a stop or when accelerating from a complete stop. Cause A slip/stick condition between the transfer case output shaft and the driveshaft slip yoke may cause this condition. Diagnostic Tips There are several resources in the electronic Service Information System which can provide the technician with information on diagnosis and repair of clunk conditions, and fix the customer’s vehicle right the first time without unnecessary parts replacement. Some of the documents available in SI include: • Symptoms – Propeller Shaft (SI Document ID #697266) • Knock or Clunk Noise (SI Document ID #697290) • Rear Drive Axle Noises (SI Document ID #700580)

General Motors has decided that a defect which relates to motor vehicle safety exists in some of the 2002-2003, model year, Cadillac Deville and Seville cars equipped with V8 (4.6 l) engine (L37/LD8), Oldsmobile Aurora V8 engined vehicles (4.0 l) engine (L47) and Pontiac Bonneville SSEi vehicles. Fuel tank pressure sensors in these vehicles is unusually sensitive to malfunction. If the sensor fails, excessive vacuum can be applied to the fuel tank during the self-test. Fuel system components can be damaged and fuel can leak from a vehicle, where it refueled. Possible symptoms of this disease are the smell of fuel from the fuel tank area, inaccurate fuel gauge readings and poor controllability. If there is an ignition source, can cause a fire.

Some of the above vehicles may exhibit an engine knock noise that begins in the first 19,000-24,000 km (12,000-15,000 mi) of use. The knock noise is most often noticed during initial start- up and typically disappears within the first 5-30 seconds (may last longer in extreme cold temperatures). The noise is usually more noticeable on the initial start-up when the temperature is below 10°C (50°F) and may be more pronounced on the first cold start following a long trip. This noise may be caused by an interaction between carbon that has formed on the piston, the piston motion and the cylinder wall. GM Powertrain Engineering, and an analysis of engines with this condition, has confirmed that the noise is not detrimental to the performance,

Condition Some customers may comment on a clunk-type noise coming from under the hood that also can be felt in the steering wheel. These conditions may be more noticeable when turning at low speeds on rough road surfaces. Diagnostic Tips Use the information below to help diagnose the source of the noise. • The lower steering column bearing may create the same noise as the intermediate shaft. Before replacing the I-shaft, verify the noise isn’t being caused by movement from the lower steering column bearing. Check the bearing for movement by pushing up and down on the I-shaft where it attaches to the steering column. • Frame Snap and/or Popping Type Noise — A frame snap or popping type noise can be duplicated on rough or

Failure to do so can result in deployment of a possible air, bodily injury or unnecessary Sir system repairs. Catera 1. Disconnect the negative battery cable. 2. remove the steering wheel. 3. remove the restrictions on inflatable wheel module coil. 4. Insert a small pointed Shilo or wire pinhole release cylinder ignition lock. 5. remove the ignition lock cylinder. Figure. Insert the tool indicated in the release PIN hole for installation:

Check battery voltage (B +) on the orange wire for automatic control of air compressor-pin f 3. If less than B + in the PIN (F), check the wiring and communication problems between the air compressor and underhood Fuse block. 4. turn off the compressor module connector alignment and check the resistance of the positive battery voltage circuit solenoid valve for exhaust and control scheme of solenoid valve exhaust.
