Fault description
DME, DME2: Hardware, plausibility

Condition for fault identification
Test condition:
If the control module is in an unlearned or incorrect
condition (injection disabled B_evasga=1), a plausibility
check is run on the value
B_masterhw based on registration of CAN communications
within the control module. If this process recognizes the
encoding in both control modules as correct, the injection is
enabled by resetting B_evasga and the status "learned" is
saved in the block
(B_sggl=1) while the encoding in the non-volatile RAM is
stored in the byte sgaab (learning). If an incorrect condition
is present the injection will only be enabled provided that
the corresponding control module is free of errors.
Terminal condition: Terminal 15=TRUE
Voltage condition:
9.5 < U < 17.9

Condition for fault memory entry
1 sec.

Action in service
