STOREDINJECTION MULTIPLEX SIGNAL ABSENT
NOTESSpecial notes:
Although the fault is stored in the computer, it is not caused by ABS/ESP components,
but it indicates that the ESP is deactivated due to an injection frame transmission fault.
Run fault finding on the injection system.
Note:
The injection does not always store these transient faults as quickly as the ABS/ESP
system. If no fault is stored in the injection computer, start the engine; if there is no fault
present, contact the Techline.
Once the fault in the injection system has been repaired, clear the ABS/ESP computer
fault memory.
The injection multiplex signal is transmitted to the ABS/ESP computer via the
Protection and Switching Unit.
Priorities when dealing with a number of faults:
Deal with faults DF152 and DF153 first, whether they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Check the condition and correct locking of the blue PEH connector of the UPC (Vdiag 44) or the grey CT1
connector of the UPC (Vdiag 48 or higher).
Carry out a multiplex network test and check the injection system with the diagnostic tool. If the fault is still
present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

Vdiag: 0A, 0B, 11, 12
NOTESSpecial notes:
Although it is stored in the computer, this fault does not cause the warning lights to
come on or generate a fault message, because the ABS/ESP system is not faulty. Run
fault finding on the automatic transmission with the diagnostic tool.
Note:
When the fault in the automatic transmission system is repaired, clear the ABS/ESP
fault memory.
The multiplex signal from the automatic transmission is sent to the ABS/ESP via the
Protection and Switching Unit.
Priorities when dealing with a number of faults:
Deal with faults DF152 and DF153 first, whether they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Using the diagnostic tool, check in the parameter screen that the PR063 "Vehicle parameters" truly correspond
with the vehicle undergoing fault finding.
Is PR063 Vehicle Parameters correct?
YES
Check the condition and correct locking of the blue PEH connector on the UPC
(Vdiag 44) or the grey CT1 connector on the USM* (Vdiag 48).
Carry out a multiplex network test.
If the fault is still present, run fault finding on the automatic transmission gearbox and
repair as necessary.
If the fault is still present, contact the Techline.
Use command VP004 Vehicle parameters to define the appropriate parameters for the
vehicle type.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a new test with the diagnostic
tool.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.

STOREDCOMBINED SENSOR SIGNAL PLAUSIBILITY
NOTESSpecial notes:
This fault means that the combined sensor signals are not consistent with the other
ESP sensors (steering wheel angle sensor and wheel speed sensors). If the fault
appears while the vehicle is being driven on a steep gradient, during a very tight turn
or while the vehicle is being transported on a lorry, train, boat, etc., with the engine
running, clear the fault and if possible check that the fault has disappeared by carrying
out a road test.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test.
Check the connection and condition of the combined sensor connector.
Ensure that the sensor is properly fixed to the body in the right direction (arrow pointing to the front of the vehicle).
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of the
tyres.
Using the diagnostic tool, calibrate the steering wheel angle in the "Electric power steering" subgroup followed by
command RZ003 "ESP sensor programming" for Vdiag 09, 0A, 0B, 12 and 11 in the ABS/ESP.
Re-establish dialogue with the ABS/ESP computer, clear the computer fault memory, carry out a road test then
check again with the diagnostic tool.
If the fault is still present, adjust the axle assembly geometries. Adjust if necessary and use the diagnostic tool to
calibrate the steering wheel angle again in the "Electric power steering" subgroup, then run command RZ003 ESP
sensor programming for Vdiag 09, 0A, 0B, 12 and 11 in the ABS/ESP.
Carry out a road test.
If the fault is still present, replace the sensor.
AFTER REPAIRClear the computer fault memory. If the combined sensor has been replaced, erase the
ESP sensor programming (Vdiag 09, 0A, 0B and 11) with command RZ003 ESP
sensor programming.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
If several computers are affected by a similar multiplex network fault, contact the
Techline to check the cases previously noted first.
Conditions for applying the fault finding procedure to stored faults:
Apply the fault finding procedure as below.
If no other computer has detected a multiplex network fault, but only the absence of ABS/ESP frames, carry out
the following checks:
–check the connection and condition (corrosion, bent terminal, crimping, etc.) of the computer connections
(tracks 14 and 35).
Repair if necessary.
Check the connection (locking) and condition (corrosion, bent terminals, crimping, etc.) of the blue PEH connector
on the UPC (Vdiag 44) or the grey CT1 connector on the UPC (Vdiag 48).
Repair if necessary.
Check the continuity, insulation and absence of interference resistance between:
Computer connector track 14 Track 7 of the blue PEH connector of the UPC (Vdiag 44)
or
Track 2 of the grey CT1 connector of the UPC (Vdiag 48)
Computer connector track 35 Track 11 of the blue PEH connector of the UPC (Vdiag 44)
or
Track 3 of the grey CT1 connector of the UPC (Vdiag 48)
Also check the insulation between these two connections. Repair or replace the wiring if necessary. If the problem
is still present, run the fault finding procedure on the multiplex network.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Even though it is stored in the computer, this fault does not cause the warning lights to
come on or a fault message. Using the diagnostic tool, run fault finding on the
instrument panel.
Note:
Once the fault in the instrument panel system has been remedied, clear the ABS/ESP
computer fault memory.
The multiplex signal from the instrument panel is sent to the ABS/ESP via the
Protection and Switching Unit.
Priorities when dealing with a number of faults:

NOTESSpecial notes:
1.DEF: This code means that the computer does not detect that the pedal is pressed
during braking (pedal pressed in relation to the pressure sensor).
2.DEF: This code means that the computer detects the pedal as pressed all the time
or that the brake light bulbs are the wrong ones.
Conditions for applying the fault finding procedure to stored faults:
