PREHEATING UNIT CONTROL
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
When the vehicle is started from cold, the injection computer controls the pre-
postheating unit so that the vehicle can be started.
Status ET007 becomes YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 becomes YES, check:
–the F2 (70A) supply fuse on the preheating unit, located on the power supply fuse
plate in the engine connection unit, below the Protection and Switching Unit,
–the resistance of the heater plugs.
Replace any plug whose resistance is not below 2 Ω.
If the vehicle starts and status ET007 remains YES during the engine operating phase,
refer to the interpretation of faults:
–DF017 Preheating relay control circuit.
–DF025 Preheating unit diagnostic connection.
After the engine is started and the preheating phase, the injection computer should stop
the pre-postheating unit operating.
Status ET007 should become NO.
In the event that the vehicle does not start and status ET007 remains NO, check the
continuity and absence of interference resistance of the following connections:
Injection computer Track A4 grey
32-track connector CTrack 9 preheating unit
Injection computer Track E2 grey
32-track connector CTrack 8 preheating unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:
–DF017 Preheating relay control circuit.
–DF025 Preheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

ET415
CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial note:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various things 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 RZ007 Fault memory, to reset this status to WITHOUT.
NONE
This status is present on the diagnostic tool when:
The computer has been reinitialised,
The computer has been reprogrammed.
Traction 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 (see 38C, ABS).
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

STATUS 7

(CONTINUED 3)
STATUS 6
Gear 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.
Inconsistency between the request and the vehicle speed
Status ET415 becomes STATUS 7 if the computer detects too great a difference
between the speed requested by the driver and the vehicle speed.
This could occur when driving with cruise control active (ET042 Cruise control/ speed
limiter: CRUISE CONTROL) and when there is a significant difference.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 changes to STATUS 7 where there is no significant difference in the
levels, contact the Techline.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

STATUS 8
Automatic transmission in defect mode.
Status ET415 becomes STATUS 8, when driving with cruise control active (ET042:
Cruise control/speed limiter: CRUISE CONTROL) and if the automatic transmission
is in defect mode.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the automatic transmission
computer.
Deal with any present or stored faults (see 23A, Automatic transmission,
interpretation of faults).
Clear the automatic transmission computer memory by running command RZ007 “Fault
memory”.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status 8 continues, contact the Techline.
Vehicle 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.
Carry out a multiplex network test, then run 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.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
