With Real Time Damping (RTD)

Circuit Description
The suspension control module receives a vehicle speed signal input from the powertrain control module via the vehicle speed signal circuit and also receives vehicle speed data over the serial data class 2 circuit. Once vehicle speed has been detected, the suspension control module compares the two inputs for accuracy.


Conditions for Running the DTC
Continuously after vehicle speed has been detected from one or both inputs.


Conditions for Setting the DTC
Class 2 vehicle speed is greater than 32 km/h (20 mph) and the calculated speed input (hard wire) is less than 4.8 km/h (3 mph) continuously for 10 seconds.


Action Taken When the DTC Sets
- Disable EVO outputs.
- DTC C0000 will be stored in memory.


Conditions for Clearing the MIL/DTC
- The suspension control module detects a vehicle speed signal from the PCM of greater than 32 km/h (20 mph).
- A history DTC will clear after not seeing the malfunction for 100 consecutive ignition cycles.
- Using a scan tool


Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
3. Tests whether the condition is module, system, or condition related.
4. Tests whether the condition has been corrected or identified as specified in the supporting text.
5. Test for an open or short in the vehicle speed signal circuit of the suspension control module.
