Diagnosis
The PDC system is connected to the diagnostic link through the I/K-Bus using the cluster/IKE as a gateway. The DISplus/Gt-1 is used for diagnosis and troubleshooting procedures when faults occur with the system.
Fault Symptom troubleshooting paths should be used to troubleshoot failures with the PDC system.
Diagnosis/Coding
Diagnosis of the GR II system is carried out with the DISplus/GT-1. On vehicles which have a cruise control module, the control module stores faults that occur with the input/output signals for cruise control operation.
Vehicle which use electronic throttle control will store system related faults in the EML or DME control module.
The MFL or MFL-CM stores faults that occur with the cruise control switch.
