ET008 is YES.
Program the UCH using SC004 Program UCH.
Apply the procedure after replacing the computer (see Replacement of components).
ET008 is NO.
If the UCH is not blank and has just been replaced, check whether the key is allocated (use command SC018 Key
check).
If the key is not allocated, allocate the keys using command SC015 Key allocation.
If the key is allocated, the UCH is operational.

WINDSCREEN WIPER PARK POSITION
NOTESNo faults should be present or stored.
Note:
The park position (rest position) is used as a reference point by the UCH when the
ignition is switched of f whilst the wipers are operating and is required for intermittent
wiper operation.
SPECIFICATIONSACTIVE
INACTIVE
Check that fuse F2 (15 A) is sound and correctly fitted in the passenger compartment fuse and relay box.
Replace the fuse if necessary.
Check the condition and connection of the 5-track (OR) connector on the windscreen wiper motor (component
code 212) and UCH connector PE3 (tabs bent, broken, oxidised).
Check that the earth on the MAS connection of component 212 is perfect.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V on connections 14A (high speed request) 14B and 14C (low speed request) of component
212 and on connector PE3 of the UCH (component code 645).
Check the mountings of the windscreen wiper motor (component code 212). Check that there is no point of
resistance on the windscreen wiper mechanism.
