Models: 1992-94 Buick Skylark 1993-96 Buick Park Avenue 1989-92 Cadillac Allante 1991-93 Cadillac Eldorado, Seville 1991-95 Cadillac DeVille 1991-95 Oldsmobile Ninety Eight 1992-93 Oldsmobile Achieva 1994-99 Pontiac Bonneville This bulletin is being revised to clarify when this bulletin may be used to turn the service suspension lamp off. Also, a step has been added to the 1991 Cadillac Eldorado and Seville repair. Please discard Corporate Bulletin Number 00-03-11-001 (Section 3 – Suspension). Some owners may bring their vehicles in for service with an illuminated service suspension light. The service suspension indicator lamp is telling the owner that the vehicle is due for strut/shock replacement, a maintenance item. The customer may elect to have passive struts installed in their vehicles due to repair cost savings and/or parts availability. The installation of passive shock/struts will result in handling characteristics which are the equal to a like vehicle without the computer controlled ride, with all other components such as tires, tire pressure, springs, etc. being equal. The installation of (4) new passive struts will cause the continued illumination of the service suspension indicator. If desired by the customer, the service indicator may be disabled AFTER THE INSTALLATION OF THE (4) NEW PASSIVE STRUTS, using the appropriate service procedure listed below. This bulletin DOES NOT authorize this procedure unless (4) NEW PASSIVE STRUTS WERE INSTALLED ON THE VEHICLE.

TOOLS REQUIRED J 34730-1A Fuel Pressure Gauge REMOVAL PROCEDURE NOTE: Before attempting any On-Vehicle Service, place a dry chemical (Class B) fire extinguisher near work area. 1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure. 2. Raise the vehicle. Refer to Lifting and Jacking the Vehicle. 3. Remove the in-line fuel filter bracket. 4. Grasp the in-fuel filter and one fuel pipe fitting. 5. Twist quick-connect fitting 1/4 turn in each direction to loosen any dirt within fitting. 6. Repeat for other fuel pipe fitting. CAUTION: Wear safety glasses when using compressed air in order to prevent eye injury. 1999 Cadillac DeVille V8-4.6L VIN Y 7. Blow out dirt-from quick-connect fittings at both ends of in-line fuel filter, using compressed air. 8. Squeeze plastic tabs of male end connector. 9. Pull connection apart. 10. Repeat for the other fitting. 11. Remove the in-line filter. INSTALLATION PROCEDURE CAUTION: To reduce the risk of fire and personal injury, before installing a new filter, always apply a few drops of clean engine oil to both pipe ends of the filter. This will ensure proper re-connection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may prevent proper re-connection it not lubricated).

The Universal Theft Deterrent (UTD) System is designed to sound the horns and flash the exterior lights when the system is armed and entry is gained forcibly through the doors or trunk. Alarms Operation of the exterior lights and horns when activated, is controlled by the Theft Deterrent Module via the Theft Deterrent Relay. Fuse B3 applies voltage to the Theft Deterrent Relay’s coil at all times. When the alarm is active the Theft Deterrent Module cycles the alarm system control driver (terminal F) on and off once per second. During this cycle ground is applied to the Theft Deterrent Relay coil and then removed. This causes the relay to energize and de-energize. The relay contacts will now cycle open and closed at the same rate as the alarm system control driver. When the Theft Deterrent Relay’s contacts are closed, the Horn, Park Lights, and Headlight Relays are grounded through the Diode Pack, and CKT 624. The relays now energize and the relays respective circuits will turn on. The Diode Pack is installed in the circuit to provide circuit isolation. If the diode pack were to short some unusual symptoms might occur such as the headlights light when the horn is sounded. Arming Arming the Theft Deterrent System is a four step procedure. The arming sequence begins when the ignition is turned OFF. This removes battery voltage at module terminal K, the ignition 1 input. Step 2 occurs when a door is opened and ground is applied to module terminal J, the tamper input. The system is still not armed so grounding the tamper input at this time does not set off the alarms. The SECURITY indicator flashes to alert the operator the system is not armed. Step 3 occurs when the doors are locked electrically, this applies battery voltage to the module’s terminal G, the system arm input. The SECURITY indicator is on steady to indicate that the system is armed. The arming sequence is completed when all doors are closed, removing ground from the module’s terminal J, the tamper input. The system is now armed. The SECURITY indicator will remain on for a few seconds. The Remote Keyless Entry (RKE) System can also arm the Universal Theft Deterrent

Tests/Procedures: 1. Ground the Violet/Yellow wire (disarm circuit) that goes to either front door and the theft alarm module. Have the keys out of the ignition and all doors closed when grounding the wire. This should disarm the theft alarm system and prevent the
theft alarm from arming. 2. Check that the interior lights do not stay on due to the wire being grounded. If they do, the illuminated entry relay will need to be removed or another method of disabling the theft alarm will have to be used. 3. Another method if the theft alarm module is faulty would be to disconnect the module and replace the Powertrain Control Module (PCM) with a new one. Potential Causes: Disarm Circuit — Ground disarm circuit. Powertrain Control Module (PCM) Disconnected Theft Alarm Module

1. Get a full understanding of the trouble symptoms by check the theft-alarm system,and then carry out troubleshooting. 2. The signals input to the ETACS-ECU from the switches which are related to the following systems should be normal. – Central door locking system – Headlight system – Horn system – Starting system In addition, the signals input to the ETACS-ECU from the following switches should be normal. – Hood switch – Liftgate switch – Liftgate key cylinder switch NOTE: 1. The ETACS-ECU may not accept the alarm cancelling signal under the following conditions. – If the liftgate key cylinder switch or door lock key cylinder switch is operated roughly – If these switches have been installed incorrectly or switches themselves are defective In such case, the alarm will work when the door is opened using a key. [However, when the door key cylinder switch has been shorted with the ignition switch ON, the ETACS-ECU judges the detection switch as faulty. Since then, it will prevent setting of alarm until the shorting is corrected.] 2. If the liftgate is opened using a key and is left opened when the door key cylinder switch system has a trouble (wiring harness damage, open circuit, etc.), the ETACS-ECU judges it as the liftgate holding mode and does not produce alarm even when the door is opened.
