• ◆ The automatic gearbox control unit -J217 informs the engine control unit whether a gear is engaged (selector lever in position 1, 2, 3, R or D) or not (selector lever in position P or N).
• ◆ When the selector lever is in position P or N the automatic gearbox control unit -J217 makes an earth connection to contact 22 on the engine control unit.

• ‒ Connect fault reader V.A.G 1551 .
• ‒ Switch ignition on.
• ‒ Select "Read measured value block" (function 08) and Display Group 19.
