Engine Speed Sensor: Service and Repair
Adaptation (Scan Tool Function 10)
Individual functions are called up by entering the appropriate adaptation channel numbers (listed in the adaptation table).
NOTE:
- Using measuring value blocks 10, 11, 12 and 15, the values that need to be transferred to the new instrument cluster can be read out before replacement.
- Adaptation channels 42, 43, and 44 (See measuring value blocks 013 and 014) must be adapted according to the oil quality (measuring value block 15).
- Adaptation channels 60, 61, and 62 are only needed when the instrument cluster communicates with the corresponding BUS system..
- Measuring value blocks 125 and 126 indicate the components that are part of the powertrain data-BUS.
- Measuring value block 130 indicates the components that are part of the comfort system data-BUS.
- Measuring value block 140 indicates the components that are part of the information data-BUS.

- Enter desired adaptation channel (adaptation table).
- Press -Q- button to confirm input.
NOTE: After changing an adaptation value or ending an adaptation channel, "Adaptation " function 10 must be performed again before selecting another adaptation channel.
Adaptation Of The Engine Speed Threshold
This function is used to adapt the offset value for the engine speed threshold to the dynamic oil pressure warning.

Adaptation
Input channel number XX
- Press buttons -3- and -0-.
- Press -Q- button to confirm input.
Indicated on display: Adaptation value is displayed, for example 0.
Channel 35 Adaptation 0 ->
<-1 3->
NOTE:
- The adaptation value of 0 corresponds to the value set at the factory for the oil pressure warning if the oil pressure drops below 1.2 bar at 1500 rpm.
- The adaptation can be performed in four steps (0-1000).
- The adaptation value of "250" changes the engine speed threshold to 1750 rpm.
- If the value "0" was changed due to a customer complaint, the changed value must be transferred when replacing instrument cluster.
- Press -> button.
Indicated on display:
Channel 35 Adaptation 0
Input adaptation value XXXXX
- Input adaptation value using keypad, filling initial positions with "O", for example, 00250.
Indicated on display:
Channel 35 Adaptation 0 Q
Input adaptation value 00250
- Press -Q- button to confirm input.
