PRE-POSTHEATING UNIT CONTROL
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
When the vehicle is started from cold, the injection computer controls the pre/postheating
unit so that the vehicle can be started.
Status ET007 changes to YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 changes to YES, check:
–the F2 (70A) supply fuse on the preheating unit,
– the resistance of the heater plugs.
Replace any plugs with a resistance greater than 2 Ω.
If the vehicle starts and the status ET007 remains YES during the engine functional
stage, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
After the engine is started and preheating, the injection computer should stop the pre/
postheating unit operating.
Status ET007 Should change to NO.
In the event that the vehicle does not start and status ET007 remains at NO, check the
continuity and the absence of interference resistance of the following connections:
Injection computer grey 32-track connector C, track A4 Track 9 preheating
unit
Injection computer grey 32-track connector C, track E2 Track 8 preheating
unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

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.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic gearbox)
Status ET415 becomes STATUS 6 when driving with the 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 RZ001
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, run
fault finding on the ABS computer and check the configuration of the tyre size stored in
the computer. If the configuration is correct, contact the Techline.
STATUS 7Lack of correlation 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.
STATUS 7 may occur when driving with the cruise control active (ET042 Cruise control/
speed limiter: CRUISE CONTROL) and on a very uneven surface.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 7 where the surface is not uneven, contact the
Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

STATUS 8Automatic gearbox 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 the present or stored faults (see 23A, Automatic transmission,
Interpretation of faults).
Clear the automatic transmission computer memory by running command RZ001 Fault
memory or RZ007 Fault memory.
Reinitialise ET415 of the injection computer by running command RZ001 Fault
memory or RZ007 Fault memory.
If STATUS 8 remains, contact Techline.
STATUS 9Vehicle 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 run fault finding on the ABS computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system,
interpretation of faults).
Reinitialise ET415 of the injection computer by running command RZ001 Fault
memory or RZ007 Fault memory.
If STATUS 9 remains, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
