DEF : CAN connection fault
NOTESSpecial notes:
Although stored in the computer, this fault is not caused by an electric power-assisted
steering failure, but by a multiplex network fault.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine is started or a steering wheel movement
from full lock to full lock.
Check that:
–there is a + 12 V before ignition feed on track 1 of the electric power steering black 2-track connector,
–there is an earth on track 2 of the electric power steering black 2-track connector,
–there is a + 12 V after ignition feed on track 8 of the steering column assembly black 8-track connector.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise change the wiring.
Check the continuity of the wiring harness for the multiplex network (see 88B, Multiplexing):
Black 8-track connector track 5CAN_L
Black 8-track connector track 7CAN_H
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Multiplex network: repair),
repair the multiplex connection, otherwise change the multiplex connection.
Check the continuity of the wiring harness for the multiplex network (see 88B, Multiplexing)
Black 8-track connector track 4CAN_L instrument panel
Black 8 track connector track 6CAN_H instrument panel
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Multiplex network: repair),
repair the multiplex connection, otherwise change the multiplex connection.
Carry out a multiplex network test and deal with any faults.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

WARNING
For TRW EPAS Vdiag 04 only, consult the fault contexts.
–If PR143 Internal fault code = 58 and if the battery voltage when the fault occurs (PR108) is above 9 V, do not
clear the fault; contact the Techline.
–If PR143 Internal fault code = 58 and if the battery voltage when the fault occurs (PR108) is less than or equal
to 9 V, run fault finding on the battery and charge circuit.
–For other values of PR143, do not clear the fault, contact the Techline.
For the other Vdiag of TRW EPAS, do not clear the fault, contact the Techline.
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after starting or a steering wheel movement from full lock
to full lock.
Special notes:
Apply the fault finding procedure only on Vdiag 04.
For Vdiag 06, 08, 0C and 12, do not clear the fault and contact the Techline.
–Check the condition and connection of the battery terminals.
–Check that the EPAS black 2-track connector is correctly locked.
–Check that the EPAS black 8-track connector is correctly locked.
–Check the condition and conformity of the EPAS fuses: on the power fuse board (70A) and on the UPC (5A).
–Check the conformity of PR108 Computer feed voltage: 12 V < PR108 < 16 V.
Check that:
–there is a + 12 V before ignition feed on track 1 of the electric power steering black 2-track connector,
–there is an earth on track 2 of the electric power steering black 2-track connector,
–there is a + 12 V after ignition feed on track 8 of the steering column assembly black 8-track connector.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise change the wiring.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.
