SUBJECT: Vehicle Surge While Speed Control Is Engaged OVERVIEW: This bulletin involves installing a new antilock brake control module. MODELS: 2001 (AN) Dakota 2001 (DN) Durango NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH SPEED CONTROL (SALES CODE NHM) AND FOUR WHEEL ANTILOCK BRAKES (SALES CODE BGK) BUILT ON OR BEFORE THE FOLLOWING DATES: DAKOTA STANDARD AND CLUB CAB VEHICLES BUILT ON OR BEFORE SEPTEMBER 12, 2000 (MDH 0912XX). DAKOTA QUAD CAB VEHICLES BUILT ON OR BEFORE SEPTEM- BER 5, 2000 (MDH 0905XX). DURANGOS BUILT ON OR BEFORE AUGUST 29, 2000 (MDH 0829XX). SYMPTOM/CONDITION: The vehicle surges while the speed control is engaged at 74-76 km/h (46-47 mph) and/or at 109-111 km/h (68-69 mph). DIAGNOSIS/REPAIR PROCEDURES: Road test the vehicle in a location where vehicle speeds of 74-76 km/h (46-47 mph) and/or 109-111 km/h (68-69 mph) can be maintained safely. Set the speed control at 74-76 km/h (46-47 mph) or at 109-111 km/h (68-69 mph). If the vehicle surges, disengage the speed control. If the vehicle still surges, further diagnosis is required. If the vehicle surges only while the speed control is engaged, perform the Repair Procedure. NOTE: DUE TO THE NATURE OF THIS CONDITION, IT MAY BE DIFFICULT TO DUPLI- CATE THE SYMPTOM. IF THE CUSTOMER INDICATES THAT THE VEHICLE SURGES AT 74-76 KM/H (46-47 MPH) AND/OR AT 109-111 KM/H (68-69 MPH) ONLY WHEN THE SPEED CONTROL IS ENGAGED, PERFORM THE REPAIR PROCEDURE.
