Fault finding - Replacement of components
The power-assisted steering computer cannot be separated from the steering column.
Before replacing the electric power assisted steering computer, the battery must be disconnected.
Procedure to follow after battery disconnection:
Every time the battery is disconnected, the steering wheel angle is invalid (remains at 0) and status ET020 is at
Status 3.
Following a road test, this will result in a fault in the Electronic Stability Program.
Therefore, every time the battery is disconnected, turn the steering wheel from lock to lock, then bring back the
steering wheel to the centre point with the wheels set straight ahead and the engine running.
Check that ET020 Steering wheel angle sensor programming becomes Status 4.
If the fault is still present, stop and restart the engine without pressing the ESP button and repeat the procedure
above.
Replacing the computer:
Each time the Electric Power Assisted Steering computer is replaced, configure the computer to the vehicle (see
SC001 Computer calibration) and program the steering wheel angle sensor (VP004 Steering wheel angle sensor
programming).
The computer must only be replaced with the battery disconnected.

CONTINUED
STATUS 1 OR STATUS 2
If the status is STATUS 1 or STATUS 2, program the steering wheel angle sensor (see Configurations and
programming).
STATUS 3
If the status is STATUS 3, turn the steering wheel to right full lock, and then left full lock; then slowly return to the
centre point and go slightly beyond.
Status ET020 should become STATUS 4.
Note:
A present or stored fault can impede STATUS 4 (make the necessary repairs, consulting the fault finding manual).
After the battery is disconnected, status ET020 is STATUS 3 and PR121 Steering wheel angle remains 0.
Consult the Replacement of components section for the procedure to follow after disconnecting the battery.
AFTER REPAIRRun a system fault check.
Repeat the conformity check.
