The problem
The traction solenoid exhaust can be obstructed due to inadequate drainage and a build-up of road contamination between the mounting bracket and the solenoid housing. The obstructed exhaust prevents the relay valve control air pressure from venting after a differential braking traction event.
The risk
This condition would keep the rear axle service brakes applied without any brake pedal movement by the driver increasing the risk of a vehicle accident.
The fix
Dealers will remove the suspect valve and install a new valve that has a modified solenoid housing which will allow for sufficient drainage and a new valve mounting bracket with increased height to reduce entry of contamination.
