target teeth.
If the checks are correct:
–the computer fault memory has been cleared,
–exit fault finding mode, switch off the ignition and carry out a road test.

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
