Fault finding – Replacement of components
COMPUTER REPLACEMENT OR REPROGRAMMING
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
– Run command SC003 Save computer data before replacing or reprogramming the computer. This enables
certain data to be saved in the diagnostic tool so that the new computer* can be reconfigured like the old one.
The saved data includes: injector codes, EGR programming, specific data for particle filter operation and vehicle
options.
– Run command SC001 Write saved data after replacing or reprogramming the computer. This command
enables the data (saved by the command SC003 Save computer data) to be rewritten in the new computer*.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything.
After replacing the computer:
– Manually enter the IMA codes for each injector by reading the code on each injector (see 13B, Diesel injection,
Replacement of components, Injector replacement).
– Enter the data specific to particle filter operation by running SC036 Reinitialise programming and select After
replacing the injection computer with no save option.
Exhaust gas recirculation valve data is programmed automatically the 1st time the new computer is switched on*.
* New computer or reprogrammed computer.
Specific to the cruise control/speed limiter operation to be carried out before reprogramming of the
computer:
Before reprogramming the injection computer, move the main cruise control/speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel
disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational.
The procedure for resetting the function is as follows:
– Vehicle ignition on.
– Position the cruise control/speed limiter switch in the rest position (the computer then detects the rest position).
– Position the cruise control/speed limiter switch in the Cruise control position to activate the Cruise control
function.
– Position the cruise control/speed limiter switch in the Speed limiter position to activate the Speed limiter function. IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Cut off all the electrical consumers (lights, interior lighting, air conditioning, radio CD, etc.).
– Wait for the engine to cool (engine coolant temperature < 60° and air temperature < 50°).
– For Vdiags 50, 58, 5C, during (re)programming of the computer, the engine fan assemblies are actuated
automatically.
– For Vdiags 18, 1C, 20, during (re)programming of the computer, the instrument panel screen displays
“Oil pressure fault”.
– Ignore this message and do not take any action in connection with it.

PRESENT
OR
STOREDCOOLANT TEMPERATURE SENSOR CIRCUIT
CC.0: Short circuit to earth
CO.1: Open circuit or short circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present during engine starting attempts or while the engine is
running.
Special notes:
If the fault is present:
– the coolant temperature: PR064 Coolant temperature is fixed at 11 9 ° C,
– the preheating phase is greater than 10 seconds,
– the low speed motor-driven fan assembly (GMV 1) is continuously supplied,
–if fan assembly 1 is faulty, then fan assembly 2 is activated on vehicles equipped
with air conditioning,
– the level 1 warning light is lit,
– the OBD warning light illuminates after three consecutive driving cycles (start the
engine
+ 5 seconds, then switch off the ignition and wait for 1 minute).
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
Check the coolant temperature sensor connections.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the coolant temperature sensor between connections 3C and 3JK.
Replace the sensor if its resistance is not approximately:
68780 Ω < X < 82780 Ω at - 40°C
12338 Ω < X < 12582 Ω at - 10°C
2140 Ω < X < 2364 Ω at 25°C
772 Ω < X < 850 Ω at 50°C
275 Ω < X < 291 Ω at 80°C
11 2 Ω < X < 118 Ω at 110°C
85 Ω < X < 89 Ω at 120°C
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection code3C,
– connection code 3JK,
between components 120 and 244.
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.
If the fault is still present, replace the coolant temperature sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
