conditioning not
switched onIf the motor-driven fan
assemblies are being
supplied continuously
without the air

active, the injection
system may be in defect

temperatureShows the engine
coolant temperature
in °C
Default value: 119 °CIn the event of a fault,
consult the interpretation
for DF001 "Coolant
temperature sensor
circuit".
9 Vehicle speed PR089: Vehicle speedGives the vehicle
speed in mph. This
parameter is
transmitted by the ABS
computer. This signal
is transmitted to the
injection on the
multiplex network.
With ignition on
PR089 = 0 mph (km/h)In the event of a fault, test
the multiplex network.
Refer to the ABS fault
finding notes for the
interpretation of possible
faults.

Passenger
compartmentET111:RCH number
setIndicates the number of
passenger compartment
resistors supplied. The
passenger compartment
resistor function
programming is performed
through the UCH.
Certain operating parameters
determine the operation of
one or more passenger
compartment resistors.
The injection computer only
receives a signal relating to
the number of passenger
compartment resistors to
control.
Warm engine
ET111 = NOIn the event of a
fault, refer to the UCH
fault finding note.
ET112:RCH cut-offStatus ET112 is indicated if
the passenger compartment
resistors are being controlled.
The computer receives the
signal to cut-off the resistors
through the UCH.
Warm engine
ET112 = YES
