Programming and Relearning




End of Line Programming Description

The TCM contains two calibrations for 4.0 and 4.6 litre engines. When a replacement TCM is fitted, the correct calibration must be selected or the control module will store a gearbox fault and 'GEARBOX FAULT' will be displayed in the message centre. The vehicle can still be driven and is not in 'limp home mode'.

For the diagnostic table, please refer to the individual code (i.e. P1602).

If the above table does not include details of the following enabling conditions: - IAT, ECT, vehicle speed range, and time after engine start-up then the state of these parameters has no influence upon the execution of the monitor.
