SET NUMBER OF PASSENGER COMPARTMENT HEATING
RESISTORS
STATUS 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:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
YES
Depending on the requirements of the injection system (power requirement, torque
reduction, etc.), the injection computer fixes the number of controlled passenger
compartment heating resistors (no more, no less).
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
NODepending on the requirements of the injection system (power requirement, torque
reduction, etc.), the injection computer fixes the number of controlled passenger
compartment heating resistors (no more, no less).
Status ET111 becomes NO when the number of activated passenger compartment
heating resistors can be freely controlled by the UCH.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

THERMOPLUNGER NO. 1, 2, 3 RELAY CONTROL
STATUS DEFINITIONACTIVE: This status indicates that the control of thermoplunger relay no. 1, no.2 and
no. 3 is active.
INACTIVE: This status indicates that the control of thermoplunger relay no. 1, no.2 and
no. 3 is not active.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
ACTIVE
Statuses ET205, ET206, ET207 are ACTIVE when:
– the engine has been started,
– and the engine coolant temperature is low (< 15°),
– and the air temperature is low (< 5°).
This program allows the engine coolant to be heated and to enable the passenger
compartment to be heated.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Heating element no.1 relay.
– AC064 Heating element no.2 relay.
– AC031 “Heating element relay no.3”.
In the event of a fault, refer to the interpretation of faults:
– DF032 “Thermoplunger no. 1 relay control circuit”
– DF033 “Thermoplunger no. 2 relay control circuit”
– DF034 “Thermoplunger no. 3 relay control circuit”.
INACTIVEStatuses ET205, ET206 and ET207 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

Refer to the Wiring Diagrams Technical Note for the vehicle to locate the fuses and
relays concerned.
Switch on the ignition and connect the diagnostic tool.
with the pre-postheating unit connected:
– connect the negative terminal of the voltmeter to connection 3FF of component 257,
– connect the positive terminal of the voltmeter to the + 12 V battery,
– run command AC001.
If the voltmeter does not indicate the battery voltage while the command is running (ten 1-second ON/OFF
cycles):
1- Check the condition of the preheating unit supply fuse F01 (70A).
Replace it if necessary.
2- Check the continuity and the absence of interference resistance of the following connections:
– connection code 3FF,
– connection code 3FY.
Between components 120 and 257.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Repair if necessary.
3- Check the connections on the preheating unit, heater plugs and injection computer.
Repair if necessary.
4- Measure the resistance of the heater plugs. If this resistance is greater than 2 Ω, replace the faulty plug(s).
5- Check the continuity and the absence of interference resistance between the following connections:
– connection code 37AB,
– connection code 37Z,
– connection code 37AC,
– connection code 37AA.
Between components 257, 680, 681, 682 and 683.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
6- Check for + 12 V on connectionBP35 of component257.

If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V after ignition supply between connections 3FB and BP9 of component 1069 and connection
3JAC of component 1074.
Measure the resistance of thermoplunger no. 3.
Replace thermoplunger no. 3 if the resistance is greater than 2 Ω.
Replace the water heater interface unit if necessary.
Using a test light, check that the water heater interface unit is properly earthed on connections 3FB and
3JAB between components 120 and 1069.
If the fault is still present, contact the techline.

If the additional heater no. 3 relay does not operate when running command AC031:
Check the additional heater no. 3 relay mounting.
check the engine management computer connections.
Repair if necessary.
if the fault is still present, check as follows that this relay is controlled by the engine management computer:
Disconnect the additional heater no. 3 relay, fit a 50 to 100Ω resistor on the mounting in place of the coil and
connect a voltmeter as follows:
Positive terminal to +12 V battery.
Negative terminal to connection 3JAB of the additional heater no. 3 relay mounting.
Clear the fault and actuate the relay using command AC031.
If the voltmeter shows the battery voltage (two, 2-second ON-OFF cycles), replace the additional heater no. 3
relay.
If the voltmeter does not show the battery voltage (two 2 second ON-OFF cycles), contact the Techline.
If the additional heater no. 3 relay is supplied by command AC031, but there is still a fault with the passenger
compartment heating and demisting, check using a wiring diagram:
– the conformity of the thermoplunger maxi-fuse,
– the presence of + 12 V battery on connection BP9 of the additional heater no. 3 relay mounting,
– the conformity of the additional heater relay 3;
– the continuity between connection 3JAC of the additional heater no. 3 relay mounting and the supply terminal
for thermoplunger no. 3.
– the conformity of the thermoplunger resistance: 0.4 Ω < X < 0.5 Ω at 20 °C,
– the presence of earth at the water chamber (thermoplunger mounting).
Also check the level of the cooling circuit and that there are no leaks.
Carry out the necessary repairs.
