ET111SET NUMBER OF PASSENGER COMPARTMENT HEATING RESISTORS
STATUS DEFINITIONThis status indicates that the injection computer is blocking any change to the number
of passenger compartment air heating resistors active (active ones are not cut off, but
no more can be added). This freeze in the number of heating resistors is in response to
vehicle needs (availability of power, need for torque etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
YESDepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required).
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
NODepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required). Status ET111
becomes NO if the number of passenger compartment heating resistors engaged can
be freely controlled by the UCH.

ET415CRUISE CONTROL/SPEED LIMITER DEACTIVATION
STATUS DEFINITIONThis status varies according to engine specifications.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various reasons for 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".
Conformity check: Engine stopped, ignition on or engine running.
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).

STATUS 8Automatic gearbox in defect mode.
Status ET415 becomes STATUS 8 when driving with the cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the automatic gearbox is in
defect mode.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test (see 88B, Multiplexing), then run fault finding on the
automatic gearbox computer.
Deal with any present or stored faults (see 23A, Automatic gearbox).
Clear the fault memory of the automatic gearbox computer by applying command RZ001
Fault memory.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If the specification STATUS 8 is still present, contact Techline.
STATUS 9Vehicle speed monitoring
Status ET415 becomes STATUS 9 if the vehicle speed received by the computer is
invalid or absent.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Test the multiplex network (see 88B, Multiplexing), then run fault finding on the ABS
computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system).
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If the specification STATUS 9 is still present, contact Techline.
