This bulletin is being revised to add model years and clarify the information. Please discard Corporate Bulletin Number 06-02-32-002C (Section 02 - Steering).
- The purpose of this bulletin is to inform technicians of the normal operating characteristics of the electric power steering system (EPS) when the steering wheel is turned in either direction or held at maximum rotation for an extended period of time.
- When the steering wheel is cycled repeatedly or turned to its maximum rotation, the power steering control module (PSCM) will command the maximum amount of current to the EPS motor. If the steering wheel is held in this position for an extended period of time, the PSCM will go into overload protection mode to avoid system thermal damage. In this mode, the PSCM will limit the amount of current commanded to the EPS motor, which will reduce the power steering assist level.
- If the PSCM detects a high system temperature and the overload protection mode is initiated, DTC C0176 System Thermal Error may set. On some models, DTC C0476 Electric Steering Motor Circuit Range/Performance may also set. These DTCs indicate normal PSCM action, to reduce the steering assist in order to prevent thermal damage to power steering system components.
