VEHICLE SPEED SIGNAL
NOTESConditions of use of the command.
Ignition on, engine stopped and vehicle speed zero.
Before using the command, check that the battery is fully charged.
This command is used to generate a speed other than 0 mph at the computer's vehicle speed wire output
(connection 47F) for users of that signal (radio, sunroof).
This command has no visible effect on the dashboard speedometer needle.
–Radio: Turn on the radio and make sure that the Adjust volume as a function of speed function is active.
Run command AC195. During the command, you should notice the volume of the sound increase and then
decrease. (See 86A, radio).
–Sunroof: This command has no visible effect on the sunroof. This command changes the activation threshold
of the anti-pinch system (the energy required to close the sunroof varies with vehicle speed due to aerodynamic
constraints). (See 87D ELECTRIC WINDOWS - SUNROOF).
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
