Stores a DTC C0550 in the ESC memory
Depending on which internal circuitry was affected by this malfunction, the ESC module will command one of the following actions:
- Command 0% PWM duty cycle in order to disable all four shock absorber solenoids.
- Ignore the steering position input.
- Provide shock absorber solenoid control based on the vehicle speed only.
- Sends a message to the IPC to display the SERVICE RIDE CONTROL message.
- Sends a message to the IPC to display the SHOCKS INOPERATIVE message.
If the disable all four shock absorber solenoids action was taken, the ESC module sends a message to the PCM to limit the speed. The PCM then sends a message to the IPC to display the MAXIMUM SPEED 129 km/h (80 mph) message.
