System Operation: Diagnosis

All inputs and outputs are monitored by the IHKS control module. Faults are stored in the EEPROM after terminal 15 has been switched off. Faults that occur sporadically can be deleted by the IHKS control module after successful self-repair. However, the entry "sporadic fault" is retained.

Unlike previous IHKS systems, the Z8 version is diagnosable via DIS/MoDIC.
