STATUS DEFINITIONACTIVE: This status indicates that the air conditioning compressor is active.
INACTIVE: This status indicates that the air conditioning compressor is inactive
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check: Engine stopped, ignition on or engine running.
ACTIVETo check the operation of the air conditioning, run command AC180 Air
conditioning compressor relay control. In the event of a fault, apply the
interpretation of DF1072 Air conditioning compressor control.

HEATING RESISTOR NO.3 RELAY CONTROL
STATUS DEFINITIONACTIVE: This status indicates that the relay is supplied.
INACTIVE: This status indicates that the relay is not supplied.
Conformity check: Engine stopped, ignition on or engine running.
INACTIVEStatuses ET734, ET735 and ET736 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
ACTIVEStatuses ET734, ET735 and ET736 are ACTIVE when the engine is started, the
engine coolant temperature is low (< 15°C) and the air temperature is low (<5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
To control the operation of the relays, run the following commands:
AC250 Heating resistor no.1 relay.
AC251 Heating resistor no.2 relay.
AC252 Heating resistor no.3 relay.
In the event of a fault, refer to the interpretation of faults:
DF992 Additional heater relay 1 circuit.
DF993 Additional heater relay 2 circuit.
DF994 Additional heater relay 3 circuit.

PR814NUMBER OF ACTIVE HEATING RESISTORS
PA R A M E T E R
DEFINITIONThis parameter indicates the number of active heating resistors and can be between 0
to 5 depending on the relays activated.
0 if no relay is active
1 if relay 1 is active
2 if relay 2 is active
3 if relays 1 and 2 are active
4 if relays 2 and 3 are active
5 if all of the relays are active
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature < 80°C
In the event of a fault, consult the interpretation of faults:
DF992 Additional heater relay 1 circuit,
DF993 Additional heater relay 2 circuit,
DF994 Additional heater relay 3 circuit.
