Fault finding - Configurations and programming
PROGRAMMING
●VP001 Enter VIN:
As it is necessary to enter the VIN each time dialogue is established with the diagnostic tool, it must be
programmed into each vehicle computer whenever a computer is replaced.
Programming procedure:
–Connect the diagnostic tool.
–Consult the fault finding procedure for the automatic transmission.
–Select configuration VP001 Enter VIN.
–Enter the VIN.
–Exit fault finding mode.
–Switch off the ignition.
–Wait for the end of Power-latch: over 10 seconds.
●VP009 Enter last After-Sales operation date:
Every time work is carried out on the automatic transmission in the workshop, enter the date of the
operation.
Select command VP009 Enter last After-Sales operation date on the diagnostic tool, then use the tool's
keypad to enter the date of the operation.
●VP015 Transfer oil condition meter:
Transfer the oil wear counter code from the old computer.
Select command VP015 Transfer oil wear counter on the diagnostic tool, then use the keypad to enter
the code found on the replaced computer.
●VP016 Enter gearbox oil service date:
Select command VP016 Enter gearbox oil service date on the diagnostic tool, then use the keypad to
enter the date found on the replaced computer.
* The immobiliser warning light will flash a few seconds after the ignition is switched off.

The fault relates to an internal computer fault.
If the fault is stored, clear the fault from the computer memory.
Switch off the ignition, wait until the end of power latch* then switch the ignition back on and re-establish dialogue:
Check for + 12 V on connection AP4 of component 119.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Check for earth on connection N of component 119.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
