Vehicle Speed Control
Defect, in the NHTSA record
Equipment description: electronic control modules installed on a mack refuse truck. The electronic control module (ecm) in these engines contain a manufacturing defect which results in intermittent electrical contact and causes incorrect electronic signals to be sent to the engine throttle control.
Consequence, in the NHTSA record
This condition can create the potential for sudden acceleration or deceleration of the engine increasing the risk of a crash.
Remedy, in the NHTSA record
Due to the potential serious consequences, the truck that has this ecm installed has been removed from service.
Products named: Mack 1997.
Report filed by MESA. Owner notification date in the NHTSA record: 9 Jun 1997.
95E017001Received 29 Jun 1995. 62 units.
Wheels
Defect, in the NHTSA record
These wheels are composed of 2 pieces - a disc and a rim which are normally welded together. These wheels lack the specified fillet welds.
Consequence, in the NHTSA record
If wheel separation occurs while the vehicle is inmotion, both steering and braking could be affected resulting in a vehiclecrash.
Remedy, in the NHTSA record
Dealers will inspect the manufacturing codes stamped on each wheel and if a wheel falls within the specified date code range, the dealer will replace that wheel.

95E003010Received 27 Jun 1995. 1,224 units.
Service Brakes, Air / Supply / Hoses, Lines/Piping, and Fittings
Defect, in the NHTSA record
Air system blockage in the air dryer occurs degrading the moisture removing capabilities of the dryer when the vehicle is operated in a cold environment and moisture accumulates and freezes in the air dryer or in the line between the dryer and the air system reservoir. The air dryer can become overpressurized causing the air dryer cartridge to separate from the mounting base.
Consequence, in the NHTSA record
If the air dryer separates from the base, the cartridge can separate sufficiently enough to cause personal injury or property damage.
Remedy, in the NHTSA record
Dealers will equip air systems with a pressure relief valve to be located between the compressor and the air dryer. This pressure relief valve is intended to vent if excessive pressure develops in the air dryer.
Products named: Mack RD 1993; Mack MR 1994; Mack MR 1995; Mack CH 1993; Mack RD 1995; Mack CL 1995; Mack RB 1995; Mack MR 1993; Mack DM 1995; Mack DM 1994; Mack DM 1992; Mack RB 1994, and 12 more.

Seat Belts / Front / Buckle Assembly
Defect, in the NHTSA record
The buckle assembly could have a large pawl to base clearance which may not allow the proper engagement of the connector.

The pawl to base clearance precludes the inability toengage the seat belt connector.
Remedy, in the NHTSA record
Inspect and replace all buckle assemblies found with improper clearance.
