Number of matched keys
▪ Up to max. 8 keys
|
|
|
|
|
|
|
Key status OK
▪ 1 = Yes, i.e. possible to read formally correct transponder fixed code (regardless of whether authorised or not)
▪ 0 = No, i.e. not possible to read formally correct transponder fixed code
|
|
|
|
|
|
Engine control unit response
▪ 1 = Yes (regardless of whether engine control unit authorised or not)
▪ 0 = No, i.e. engine control unit in run-on mode 1)
|
|
|
|
|
Starting authorised
▪ 1 = Yes
▪ 0 = No, i.e. vehicle key not/incorrectly matched or engine control unit incorrectly encoded/defective
|
|
|
|
|
|
1) Depending on engine control unit, measured value block is set for 10 ... 30 s after switching off engine and ignition to "0 = Engine control unit response no", i.e. engine control unit released and no fault present. Start self-diagnosis again as a check => Page 01-358.

|
|
|
|
|
Variable code authorised
▪ 1 = Yes
▪ 0 = No, i.e. variable code not authorised (arithmetic rule for variable code in key not the same as in dash panel insert)
