CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various factors that cause deactivation of the cruise control/speed limiter function, due to a
driver request or the external environment (e.g. STATUS 1).
IMPORTANT
Clear the fault memory by running command RZ001 Fault memory to reset this status to NONE.
WITHOUTThis status is present on the diagnostic tool when:
The computer has been reinitialised.
The computer has been reprogrammed.
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and traction control is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
“Fault memory”.
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-lock
Braking System).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
