Notes on display group number 125
^ If "I " is displayed, communication from the corresponding control module to the Transmission Control Module (TCM) is 0.K.
^ If "0 " is displayed and not trouble code has been set in the DTC memory, the corresponding control module does not have CAN capability (or is faulty).

Adaptation
Adaptation must be performed after the following operations:
^ After replacing the Transmission Control Module (TCM) -J217
^ After coding the Transmission Control Module (TCM)
^ After reprogramming (flash) the Transmission Control Module -J217

Requirement:
^ No trouble codes in the DTC memory, read DTC memory.

Adaptation for driving forward
- Read Measured Value Block display group 010, engine at idle





Display on VAS 5051
^ Check whether transmission fluid temperature in display field 3 is higher than 60°C. A short test drive may be necessary to reach this temperature.
^ Drive forward briefly and then brake to a stop again.
^ Check display in display field 2.
^ Display must from change "ADP. is running" to "ADP. O.K."
If the display does not come up as described
- Repeat start from stop and braking procedure until "ADP. O.K." is displayed.
If the specified value "ADP. O.K." is not obtained
^ Read DTC memory and correct malfunction. Adaptation must be performed again afterward.
^ Perform adaptation for driving in reverse.

Adaptation for driving in reverse:
- Read Measured Value Block display group 011, engine at idle





Display on VAS 5051
^ Drive backward (in reverse) briefly and then brake to a stop again.
^ Check display in display field 2.
^ Display must from change "ADP. is running" to "ADP. O.K."
If the display does not come up as described
- Repeat start from stop and braking procedure until "ADP. O.K." is displayed.
If the specified value "ADP. O.K." is not obtained
- Read DTC memory and correct malfunction. Adaptation must be performed again afterward.
