ET088REQUEST TO START COMPRESSOR
STATUS
DEFINITIONACTIVE: This status indicates that the compressor is engaged.
INACTIVE: This status indicates that the compressor is not engaged.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Engine running, engine coolant temperature > 80˚C
"ACTIVE"The air conditioning request has been made by the driver when pressing one of the
air conditioning controls (Auto or AC).
Status ET088 becomes ACTIVE and the computer authorises or does not authorise
air conditioning depending on the operating conditions.
If status ET088 does not become ACTIVE when the control button is pressed, refer
to the air conditioning fault finding note (see 62A, Heating system, 62B, Climate
control or 62C, Manual air conditioning).
Note: Compressor operation is only authorised when the engine is running.
Conformity check with engine stopped and ignition on.
"INACTIVE"When the driver deactivates the air conditioning, status ET088 must become
INACTIVE.
If it does not, refer to the air conditioning fault finding note (see 62A, Heating system,
62B, Climate control or 62C, Manual air conditioning).
Note: Compressor operation is only authorised when the engine is running.

DEFINITIONYES: This status indicates that the number of activated passenger compartment
heating resistors is set by the injection computer.
NO: This status indicates that the number of passenger compartment heating
resistors can be freely controlled by the UCH.
NOTESSpecial notes:

temperature > 80˚C
"YES"Depending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required)
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
"NO"Depending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required)
Status ET111 becomes NO if the number of passenger compartment heating
resistors engaged can be freely controlled by the UCH.
