Erroneous Generating Of Diagnostic Trouble Code P0606 00

Fault symptom
Diagnostic trouble code P0606 00 is indicated

Criteria
There are about ten different situations, both software and hardware related, which generate the above diagnostic trouble code.

Diagnostic help
The erroneous generating of the diagnostic trouble code is due to the software and applies only to cars equipped with automatic transmission. ECM for T8 must not be replaced.

Procedure
In order to establish whether the diagnostic trouble code has been generated in error, follow the instructions below.
1. Clear the diagnostic trouble code using Tech 2
2. Test drive the car for two driving cycles of approx. 5 minutes each (city driving). Make sure that the ignition key is in the OFF position for at least 5 seconds between the two driving cycles.
3. Read the diagnostic trouble codes using Tech 2 following the second driving cycle.
4. If the diagnostic trouble code has not reoccurred it was generated in error. If it does reoccur then follow normal fault diagnosis.

NOTE: The above fault diagnosis is performed in order to avoid unnecessary replacement of ECM modules. New software which rectifies the fault is being released.
