ET144
HIGH-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS DEFINITIONACTIVE: This status indicates that the high-speed fan assembly relay is actuated.
INACTIVE: This status indicates that the high-speed fan assembly relay is not
actuated.
ACTIVE
When the coolant reaches 99°C, the diesel computer activates the high-speed fan
assembly relay and status ET144 becomes ACTIVE.
The relay then supplies the fan assembly and the cooling fan begins to turn.
Run command AC039 High-speed fan unit relay and visually check that the cooling
fan is turning. If this is not the case, carry out the following operations:
– check the condition of fuse FM15 (60A) and the motor relay R10,
– disconnect the fan unit relays, check their operation and the condition of the
connections,
– repair if necessary,
– check for a + 12 V on connection 49B of components 597 and 262, when the high-
speed relay is actuated.
Check the continuity and the absence of interference resistance on the following
connections:
–Connection codes 3JP and 49B between components 120, 957 and 262.
If the connection or connections are faulty and there is a repair method (see Technical
Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair), repair the
wiring, otherwise replace it.
INACTIVEIf the engine temperature is less than 99°C, the engine cooling fan cannot switch on
and the high-speed fan assembly relay should not be actuated.
Status ET144 becomes INACTIVE when the control relay and the engine cooling fan
are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system operation
programming.
Note:
Cruise control can be activated when the vehicle speed exceeds 20 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 (eg. STATUS 1).
IMPORTANT:
Clear the fault memory by running command RZ007 Fault memory, to reset this status to WITHOUT.
NONE
This status is present on the diagnostic tool if:
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 cruise control active (ET042:
Cruise control/Speed limiter: CRUISE CONTROL) and upon a traction control
request.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 1 without a traction control request (see38C, ABS).
STATUS 2Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes "STATUS 2" when driving with cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and the brake pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 2 without pressing the brake pedal, consult the
interpretation of statuses ET704 and ET705 Brake contact No 1 and No 2.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 5
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal indicating that the brake pedal switch has been
pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
– of status ET042 Cruise control/speed limiter,
– of status ET703 Cruise control/speed limiter buttons,
– of status ET704 Brake contact no. 1,
– and status ET705 Brake contact No 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 changes to "STATUS 5", deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic
gearbox)
Status ET415 becomes STATUS 6 when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) and:
– If the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is in neutral on an automatic gearbox.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into neutral on an automatic transmission, test
the ABS computer and check the configuration of the tyre size stored in the computer. If
the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 9
Vehicle speed monitoring
Status ET415 changes to 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.
Carry out a multiplex network test, then Perform fault finding on the ABS computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system,
interpretation of faults).
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status 9 continues, contact the Techline.
STATUS 10Monitoring by injection computer
Status ET415 becomes "STATUS 10" when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) if the injection computer detects
a fault anywhere in the engine management system, or an engine speed that is too high
or too low.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then Perform fault finding on the injection computer.
Deal with present or stored faults.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status 10 continues, contact the Techline.
