Model Year:
As of '99 (X)
Concerns:
Failure of remote control due to replacing battery improperly.
Information:
Replacing the battery improperly can cause the processor in the remote control to operate incorrectly so that the remote control no longer functions. For this reason, please inform your customers who purchase a battery for their remote control to not replace the battery themselves.
Replace the battery for the customer as described in the following work procedure to avoid a malfunction of the processor and thus a remote control failure.
- Work Procedure, Step 1, "Replacing the remote-control battery"
After replacing the battery, check if the remote control functions. If the remote control does not function, the processor could have stopped. If this is the case, the LED of the remote control either does not light when the button is pressed or it lights continuously, i.e., longer than length of time the button is pressed. The processor must be restarted.
- Work Procedure, Step 2, "Restarting the processor"
The newly printed editions of the vehicle Owner's Manuals will contain a note that the battery for the remote control should be changed by the Porsche dealer.
