1999 Chevrolet Suburban C1500 Catalytic Converter Damage Due to Installation of Alarm Systems

in an effort to determine the root cause of catalytic converter damage, has determined that aftermarket alarm systems incorrectly installed in vehicles have the potential to cause misfire codes and damage to the converter. These alarm systems use a circuit interrupt which utilizes the ignition circuit on the vehicles. These alarm systems utilize mechanical relays and normal vehicle movement can trigger these relays to engage and disengage the ignition circuit while the vehicle is in motion. These disruptions of the ignition circuit, which occur in milliseconds, may cause more fuel to be commanded. Over time, this dumping of fuel on and off again can cause misfire codes and ultimately damage the converter assembly. IMPORTANT: Engineering could not identify any alarms that utilize solid state circuitry that would eliminate this concern. Because of this, it has been determined that all alarm systems must be routed through the starter circuit in order to avoid this condition.

This bulletin provides the procedure for replacing the manual transmission gear shift lever assembly and transmission oil. • TGS REPLACEMENT 1. Place the vehicle so it may be raised on a hoist and release the parking brake. 2. Unbutton the shift lever boot hook (A) and open the shift lever boot. 3. Remove the shift lever knob by turning it counterclockwise. 4. Raise the vehicle off the ground and remove the heat shield by unfastening 6 mounting bolts (B). 5. Unfasten the two nuts (C) at the flange in front of the catalytic converter. NOTE: Torque specification: 28.9 ~ 43.4 lb-ft. 6. Unfasten the two nuts (D) that connect the center pipe to the muffler assembly. NOTE: Torque specification: 28.9 ~ 43.4 lb-ft. 7. Disengage the rubber exhaust hanger on the center pipe and remove the center pipe together with the secondary catalytic converter. 8. Draw a straight line across the front propeller shaft rubber coupling (a) and the transmission companion flange(b). This will be used to align when reinstalling. CAUTION: Use care not to exchange locations and directions of bolts and washers when reinstalling to prevent balance issues. 9. Remove the 3 propeller shaft mounting nuts (E) holding the rubber coupler to the transmission output flange. NOTE: Tightening torque : 90~110Nm (9.0~11.0 kgf.m/65~79.5Ib-ft) 10. Lower propeller shaft to gain access to the shift lever.
