- Summary
- Supersedes Technical Service Bulletin Group 43 number 13-12 dated February 4, 2013. The vehicle pulls to one side. The suspension height is uneven and the vehicle is crooked. One wheel location of the suspension is stuck in the raised position. The control system cannot be programmed. entries may be stored in the level control system control module, J197 (34). The residual pressure holding valve of an air spring may be stuck closed, not allowing the air spring to reduce its height. This valve's function is to ensure a minimum air spring pressure of 50 psi in the event of a large leak. For example, if an air supply line was severed by road debris, the residual pressure holding valve would keep the air spring from completely deflating.
