COMMAND (continued)
SPECIAL COMMANDSAC195:Vehicle speed signal.
This command sends a speed other than 0 mph on the computer's vehicle speed wire output
(Track 33) to users of that signal (xenon bulbs, radio, sunroof).
Note:
This command has no visible effect on the dashboard speedometer needle.
Xenon bulbs: Switch on the dipped headlights and run command AC195. You should see a slight
change in the height of the headlight beam (depending on vehicle speed, the height of the beam is
adjusted to improve visibility).
–Radio: switch on the radio and check that the speed-dependent volume control function is active.
Run command AC195. During the command, you should notice the volume of the sound increase
and then decrease.
–Sunroof: this command has no visible effect on the sunroof. This command changes the activation
threshold of the anti-pinch system (the pressure exerted by the sunroof varies with vehicle speed
due to aerodynamic factors).
AC196:Request to switch on hazard warning lights.
This command sends the UCH a request to switch on the hazard warning lights to test their operation
during emergency braking (depending on UCH configuration).
SC001: Check target teeth.
This command tests the condition of the teeth on each wheel. Select command SC001 Test target
teeth. The test result should show 48 teeth.
SC006: Bleed the hydraulic unit and brake circuits.
Use this command if abnormally long brake pedal travel is noted during a road test with ABS control
(the system must have been bled beforehand by the usual procedure).
Select the SC006 "Bleed hydraulic unit and brake circuit" command and follow the instructions
given by the diagnostic tool.
