1
Computer + after ignition
feed
ET001: Computer + after ignition feed PRESENT
Indicates that the computer is supplied with a + after ignition
feed.
– Present – Absent
In the event of a malfunction, carry out
the diagnostic procedure for P0560
"Computer supply voltage" or P0685
"Main relay circuit".
2 Starting
ET076: Starting AUTHORISED
Indicates whether or not starting has been
authorised by the injection AUTHORISED: The injection has given starting authorisation.
PROHIBITED: The injection has not given
starting authorisation.
If PROHIBITED, carry out a full diagnostic procedure on the preheating system.
3 Engine
ET038: Engine
+ after ignition feed
Gives the current status of the engine.
– + after ignition feed – CRANKING
– RUNNING – MAINTAINED
SUPPLY: Supply maintained during the power latch phase.
– Stalled: When the engine has stalled.
– Protected: When a malfunction appears or when the engine speed is limited to a certain engine speed.
NONE.

1 Immobiliser
ET003: Immobiliser INACTIVE
Gives the status of the immobiliser system.
– INACTIVE: The injection computer has recognised the immobiliser code transmitted by the UCH.
– ACTIVE: The injection computer does not recognise the immobiliser code transmitted by the Inteligent Key unit or BCM.
If ACTIVE, follow the associated "help"
given in the tool.
2 Code
programmed
ET006: Code programmed YES
States whether the immobiliser code has been programmed by the computer or not.
– YES: Code programmed – NO: Code not
programmed by the ECM.
If NO, replace ECM.
3 Battery voltage
PR074: Battery voltage 13 V < PR074 < 14 V In the event of a malfunction, run the diagnostic procedure for the "Charging

1
Air conditioning
present
ET079: Air conditioning present
YES
States whether the vehicle is fitted with air
conditioning or not.
– YES: Air conditioning is detected by the ECM.
– NO: Air conditioning is not detected by the ECM.
If not consistent with the vehicle equipment, carry out the multiplex network test and apply the relevant procedure.
2
Compressor engagement
request
ET088: Request to start compressor INACTIVE
The injection requests the IPDM E/R (via the multiplex network) to start the compressor – ACTIVE: The multiplex
network should not be faulty on the Automatic Transmission, IPDM E/R.
The UCH should request the injection to be engaged. The refrigerant pressure sensor should not be faulty. Satisfactory engine operating conditions (coolant temperature, engine load etc.).
– INACTIVE: One of the above conditions has not be fulfilled or no request has been made by the driver so ET004 = NO.
NONE.

3 Air conditioning authorisation
ET004: Air conditioning authorised NO
Non operational information, designed
solely for trouble diagnosis purposes.
– YES: Satisfactory engine operating conditions (coolant temperature, engine load etc.). The vehicle is not in a specific movement phase (hill start or stop etc.).
– INACTIVE: One of the above conditions has not be fulfilled or no request has been made by the driver so ET088 = INACTIVE.
NONE.
4 Refrigerant pressure
PR037: Refrigerant pressure.
Gives the value in BAR for the refrigerant fluid
in the system.
2 Bar < PR037 < 27 Bar Default value: 0 Bar.
If there is a problem:
apply the diagnostic procedure for P0530
"Refrigerant fluid sensor circuit". If the DTC persists, replace
the refrigerant sensor.
5 Engine speed
PR055: Engine speed Cold: 900 rpm V Warm: 805 rpm
Gives the engine's rotational speed in
rpm.
In the event of a malfunction, apply
the diagnostic procedure for P0335 Engine speed sensor
circuit.

6 Fast idle speed request
ET023: Fast idle speed request
ABSENT
The BCM requests fast idle speed from the
injection.
If ET023 is incorrect, carry out a multiplex network test using the diagnostic tool. If the test is correct refer to
the IPDM E/R diagnostic procedure
7 Coolant
temperature
PR064: Coolant temperature Warm: 90°C
Gives the coolant temperature in°C.
Default value: 80°C.
In the event of a malfunction, refer to
parameter interpretation PR064
"Coolant temperature".
8 Vehicle speed
PR089: Vehicle speed Gives the vehicle speed in kph. This parameter is transmitted by the ABS control unit. This
information is transmitted to the
injection on the multiplex network.
Test the multiplex network.
Refer to ABS trouble diagnosis.
