The problem
On certain trucks, a malfunction in the solenoid valve May allow air to be released to fifth wheel latch when the park brake is engaged.
The risk
This condition could cause the fifth wheel latch to release inadvertently when the park brake is engaged, creating the potential for loss of the trailer. A crash could occur without prior warning.
The fix
Dealers will add an additional solenoid valve in series with the existing pneumatic circuit for the fifth wheel air release. The recall began on August 9, 2004. Owners should contact Volvo at 1-800-528-6586.
