Component:
Service brakes, air:antilock
Manufactured:
05/31/2000 - 08/30/2000
Affected:
30,000
Defect:
Vehicle description: school buses, medium duty trucks and tractors built with bendix air abs with an ec-17 1030r electronic control unit (ecu), there have been reports of unwanted abs activation at low speeds caused by 1) chafed abs wheel speed sensor wires on rotating parts or 2) a damaged component at the wheel end that generates a certain type of erratic sensor signal.
Consequence:
This condition could cause the abs ecu to exhaust the air at the air brake modulators for one or more of the wheels. this could result in extended braking distances and a possible crash.
Correction:
Dealers will replace the abs ecu.
Notes:
Owner notification began december 14, 2000 for the b7 series school buses and on march 15, 2001, for the medium duty trucks and tractors. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1022 or gmc at 1-800-462-8782. also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).
Campaign:
02V183000 on 07/22/2002
Component:
Fuel system, gasoline:storage:tank assembly:mounting
Manufactured:
05/31/2001 - 08/30/2001
Affected:
222
Defect:
On certain medium duty trucks equipped with 8.1 l engines and left hand or dual fuel tanks, some of these vehicles have a condition where the fuel filter-to-component box mounting bolts are reversed. with the bolts reversed, the threaded bolt end is oriented toward the front wall of the left hand fuel tank.
Consequence:
In the event of a frontal crash, the threaded end of the bolts could pierce the front wall of the fuel tank resulting in flue leakage. if an ignition source were present, fuel leakage could result in a vehicle fire.
Correction:
Dealers will inspect and correctly install the two fuel filter mounting bolts, if necessary. owner notification began august 8, 2002. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020 or gmc at 1-800-462-8782.
