INACTIVEIf the brake lights are working:
check the continuity and make sure there is no interference resistance on the following
connection:
Connection code 5A between components 160 and 120/645/119.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
disconnect the switch and carry out the following checks:

* Opening Cyclic Ratio AC011
RAIL PRESSURE REGULATOR
NOTESThis command enables the operation of the injector high-pressure regulator circuit to
be checked.
Step 1
Measure the pressure regulator resistance between tracks 1 and 2.
– Replace the regulator if the resistance is not approximately: 3Ω ± 0.5 at 20 °C.
Check the continuity and the absence of interference resistance of the following connections:
Injection computer brown 48-track connectorB, trackM4 track 2 of the rail pressure regulator
connector.
+ 12 V after relaytrack 1 of the rail pressure regulator
connector.
If, when running command AC011, you can hear a slight whistling noise and the rattling from the regulator, go to
Step 2. Otherwise, ensure that the computer output is functioning correctly:
●Using a voltmeter:
With the solenoid valve connected, connect the voltmeter earth lead to track 2 of the fuel pressure solenoid valve
and the positive cable to track 1. Clear any fuel pressure solenoid valve faults, then run command AC011:
The voltmeter should display two successive voltages: ~ 2.5 V for an OCR at 20 % then ~ 8.75 V at an
OCR at 70 % (ten cycles)
●Or using an oscilloscope (range 5 V/division and with time base 1 ms/division):
With the solenoid valve connected, connect the earth of the oscilloscope to the battery earth and the positive test
pin to track 2 of the fuel pressure solenoid valve. Clear any fuel pressure solenoid valve faults then run command
AC011:
The oscilloscope should display a square-wave signal of 12.5 volts amplitude at a frequency of 185 Hz
(with an OCR going successively from 20 to 70 %).
– If the measurement is correct, replace the regulator.
– If the measurement is not correct, contact the Techline.
Step 2, next page
AFTER REPAIRRestart the conformity check from the beginning.

Check the battery charge and the condition and tightness of the terminals.
Ensure that engine speed reaches 250 rpm when the starter motor is
operated. This is displayed on the parameter screen.
Check the engine earths.
Check the conformity of the inertia switch (according to equipment).
Check the presence and conformity of fuel in the tank. Run test 5 Diesel
fuel conformity check.
Check for the 12 V after relay feed on tracks G1 and M2 of connector B
on the engine management computer (via injection relay).
Check the engine fuses (and their mountings, wires and terminals).
test
Operate the starter:
Does the pressure increase in the rail:
Rail pressure = ~ 170 bar at ~ 250 rpm?
NO
Run a fault finding check on the regulator and high pressure pump by
applying the interpretation of command AC011 Rail pressure regulator.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
