System Fault Message

If a fault is detected by the ADCM, a message is sent via the high speed CAN (controller area network) to the instrument cluster and the message ADAPTIVE DYNAMICS FAULT is displayed. The ADCM also logs an appropriate DTC (diagnostic trouble code). The ADCM can be interrogated using a Jaguar approved diagnostic system.

When a fault is detected, the ADCM implements a strategy based on the type of fault. If there is an electrical power fault, or the ADCM cannot control the dampers, they default to the firm condition. If a sensor fails that only affects one or more control modes then an intermediate damper setting is used as the lower threshold and the remaining working modes can demand higher damping as required. In the event of a high speed CAN bus fault, the dampers are fixed at an intermediate setting (no control) or default to the firm condition, depending on the severity of the fault.
