The problem
On certain heavy-duty class 8 trucks, the assembled engine pre-heater jumper wiring harness was incorrectly assembled.
The risk
The engine pre-heater could overheat resulting in damage to the pre-heater and other engine heat sensitive components near the pre-heater and the ability to re-start the engine could be compromised, increasing the risk of a crash.
The fix
Dealers will repair the affected circuits in the jumper wiring harness connector. Owner notification is expected to begin during March 2004. 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 Volvo trucks at 1-800-528-6586.
