The exception is diagnostic trouble code (DTC) MCC 1-1-1 for certain control modules
NOTE:
On the MCC/STANDARD control modules introduced at production start-up of the C70 series must fault-tracing for MCC 3-4-2 be carried out if
the REC button orange indicator LED flashes once at ignition on (diagnostic trouble code (DTC) stored) but
the control module flashes out diagnostic trouble code (DTC) 1-1-1.
This applies to control modules marked "S2", "S3" or "S4". See illustration.
