Arrangement of elements of management

Codes of diagnostics of automatic transmission 42RE (engine of 4.0 l)

The blinking codes are displayed by a control lamp of switching off of the raising transfer.

Before reading of codes check reliability of all electric sockets and level of transmission liquid.

Switch on and off ignition twice, again include. The switch of the mode of the raising transfer has to be in normal – the included situation.

Delivery of codes will begin immediately.

The code 55 designates the end of delivery of codes.

For removal of codes take out for a short time a transmission safety lock in a box or a plait of conducting. Do not disconnect the battery since codes of other control systems of the car will be removed.

When using the scanner (DRB III is recommended to Chrysler) or the personal computer for reading of codes connect it to the diagnostic socket located in the left part of the dashboard over an accelerator pedal.
