VEHICLE SPEED
PARAMETER
DEFINITIONGives the vehicle speed in mph (km/h).
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
This parameter is transmitted by the ABS computer.
This signal is transmitted to the injection on the multiplex network.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C.
In the event of a fault, test the multiplex network (see 88B, Multiplexing).
Then complete fault finding on the ABS computer (see38C, Anti-lock braking system).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

CRUISE CONTROL SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the cruise control setpoint.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
No faults must be present.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– or after a customer complaint (lack of power, smoke etc.).
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C.
Indicates the cruise control cruising speed.
Cruise control can only be activated for a speed V > 18 mph (30 km/h).
In the event of a fault, refer to the interpretation of statuses ET042 Cruise control/Speed limiter, ET556 Driver
