Vdiag No.: 44, 48
MAIN COMPUTER STATUSES AND PARAMETERS (continued 1):
NOTESOnly check conformity after a full check with the diagnostic tool.
The values shown in this conformity check are given as examples.
Application conditions: Engine off, ignition on.

Check or actionDisplay and notes Fault finding
Fuel
temperaturePR063: Fuel
temperature.
Cold = PR064
Warm: 50°CGives the fuel temperature
in °C. This value is supplied by
"the fuel temperature sensor".
Default value: 30°C.In the event of a fault, apply
the fault finding procedure for
fault DF098 "Fuel temperature
sensor circuit".
Air circuit
pressure.PR035: Atmospheric
pressure.Indicates the atmospheric
pressure in mbar. The sensor is
built into the computer.
600 mbar < Cold < 1050 mbar
600 mbar < Warm < 1050 mbar.If not consistent, check that
PR035 = PR032 = local
atmospheric pressure, with
the engine stopped and
the ignition on.
PR032: Inlet pressure.Indicates the pressure in the
inlet circuit in mbar.
PR032 = Local atmospheric
pressure.
Rail pressurePR038: Rail pressure.
Cold: 260 bar.
Warm: 230 bar.Indicates the pressure, in bar, of
the diesel fuel in the injector
rail. This pressure is supplied
by the sensor on the rail.
Default value: 2000 barIn the event of a fault apply
the fault finding procedure for
fault DF007 "Rail pressure
sensor circuit".
EngineET038: Engine
runningIndicates the current status of
the engine.
- UNDER + AFTER IGNITION
FEED
- UNDER STARTER
- RUNNING
- SUPPLY MAINTAINED: Supply
maintained during the power
latch phase.
- STALLED: When the engine has
stalled.
- PROTECTED: When a level 2
fault has appeared or when the
engine speed is locked at
a certain value.NONE

Air conditioning
presentET079: Air
conditioning
present.
YESIndicates whether the vehicle is fitted with air
conditioning or not.
- YES: Air conditioning is detected by the injection
computer.
- NO: Air conditioning is not detected by the
injection computer.If inconsistent with
the vehicle
equipment, perform
a multiplex network
test and apply the
associated
procedure.
Compressor
activation
requestET088:
Compressor
activation
request.
INACTIVEThe injection requests the Protection and
Switching Unit (via the multiplex network) to
start the compressor.
- ACTIVE: The multiplex network must not be faulty
on the Automatic transmission, Protection and
Switching Unit, or UCH systems. The UCH should
request the injection to be engaged. The coolant
pressure sensor must not be defective. Satisfactory
engine operating conditions (coolant temperature,
engine load etc.).
- INACTIVE: One of the above conditions has not
been met or no request has been made by the
driver, so ET004 = NO.NONE
Air conditioning
authorisedET004: Air
conditioning
authorised.
NONon operational information, designed solely
for fault finding purposes.
- YES: Satisfactory engine operating conditions
(coolant temperature, engine load, etc.). The
vehicle is not in a specific movement phase (hill
start, start from stop etc.).
- NO: One of the above conditions has not been
met or no request has been made by the driver, so
ET088 = INACTIVE.NONE

COLD LOOP SUB-FUNCTION (continued 2):
*When the air conditioning is requested with the engine idling and the vehicle speed = 0 mph (0 km/h),
ET022 will always be ACTIVE and ET021 INACTIVE (unless refrigerant pressure > 15 bar, vehicle speed
= 0 mph (0 km/h) and high coolant temperature). The fan assemblies are disabled under certain coolant
temperature conditions when driving.
When the UPC stops receiving multiplex transmissions from the injection, the fan assemblies are
constantly activated.
NOTESOnly check conformity after a full check with the diagnostic tool.
The values shown in this conformity check are given as examples.

fan assembly
request.
INACTIVE.The injection requests the UPC to start the fans.
- INACTIVE: The request was not made by the
injection because ET088 = INACTIVE and ET004
=NO.
- ACTIVE: The request was made by the injection.
ET088 = ACTIVE and ET004 = YES.
(Correct refrigerant pressure and vehicle speed
= 0 mph (0 km/h) or high coolant temperature).
NONE
ET021: High
speed fan
assembly request.
INACTIVE.The injection requests the UPC to start the fans.
- INACTIVE: The request was not made by the
injection because ET088 = INACTIVE and ET004
=NO.
- ACTIVE: The request was made by the injection.
ET088 = ACTIVE and ET004 = YES.
(Refrigerant pressure > 15 bar and vehicle speed
= 0 mph or high engine coolant temperature).
