RESET TRANSAXLE COMPENSATION CODE
NOTICE:
The transaxle compensation code can be reset only with the intelligent tester.
HINT:
The TCM memorizes the condition that the ECT controls the automatic transaxle assembly and engine assembly according to those characteristics. Therefore, when the automatic transaxle assembly, engine assembly, or TCM has been replaced, it is necessary to reset the memory so that the TCM can memorize the new information.
Reset procedure is as follows:

  1. Shift the shift lever to the N or P position.

  2. Turn the ignition switch off.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the ignition switch on and push the intelligent tester main switch on.
