*RCH = Passenger Compartment Heating ResistorET017
NUMBER OF RCH* REQUIRED
NOTESThere must be no present or stored faults.
The status, depending on the conditions, will be 0, 1, 2, 3, 4 or 5.
Special note:
Manual air conditioning (not automatic)
Defined by the UCH according to the engine coolant temperature, the external
temperature and electrical availability.
Climate control
Defined by the UCH according to the engine coolant temperature, the external
temperature, electrical availability, the internal temperature and the user's request.
The passenger compartment heating resistor control conditions are:
Manual air conditioning (not automatic):
ET169 Engine is Running,
ET015 Passenger compartment fan Active,
PR002 Exterior temperature < 5˚C
Engine coolant temperature < 50˚C (refer to injection computer),
Electrical availability - 60%, alternator load < 70% (refer to the Power and Switching Unit).
Climate control:
ET169 Engine is Running,
PR002 Exterior temperature < 5˚C
Engine coolant temperature < 50˚C (refer to injection computer).
Electrical availability - 60%, alternator charge < 70% (refer to the Power and Switching Unit).
Heat demand by the user (refer to the climate control computer).
Check the consistency of these statuses and parameters.
In the event of a fault, consult the interpretation of these statuses and parameters.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

*RCH = Passenger Compartment Heating ResistorET018
NUMBER OF RCH* AUTHORISED BY ALTERNATOR
NOTESThere must be no present or stored faults.
Special note:
This information is usable only on vehicles fitted with passenger compartment heating
resistors.
Calculation performed by the UCH according to the alternator power available
(information supplied by the UPC).
This information allows the number of passenger compartment heating resistors to be
supplied depending on the available power.
The status, depending on the conditions, will be 0, 1, 2, 3, 4 or 5.
In the event of a fault, perform fault finding on the UPC (see 87G, Engine compartment connection unit).
The parameter PR010 (UPC) of the alternator charge should be less than 70% so that the passenger
compartment heating resistors can be authorised by the alternator.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

RESISTORS AUTHORISED BY THE INJECTION
NOTESThere must be no present or stored faults.
Special note:
Calculation performed by the UCH depending on the maximum power authorised by
the injection computer.
This information allows the number of passenger compartment heating resistors to be
supplied depending on the engine load.
The status, depending on the conditions, will be 0, 1, 2, 3, 4 or 5.
In the event of a fault, run fault finding on the injection system (see 13B, Diesel injection or 17B, Petrol injection).
Conditions for authorisation of passenger compartment heating resistor by the injection:
–the injection system status ET111 Fixed number of RCH* should be NO,
–the injection system status ET112 RCH* cut-off should be NO.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
