Diagnostic – Failure locating tree
Ensure that not CLIP tester is the failure cause – try its communication with some other
vehicle UCE airbag. If CLIP tester is not the failure cause and the dialogue is not established
with no other computer of the same vehicle, it is possible that another damaged computer is
perturbing the diagnostic lines L and K.
Proceed by consecutive disconnection for damaged computer locating.
Check the battery voltage and perform the necessary interventions in order to obtain an
adequate voltage, with the value between 10.5 volts and 15 volts.
Check the presence and condition of the supply fuse of UCE airbag.
Check the correct connection of the computer connector and the cables condition.
Check the computer correct supplying:
- Disconnect UCE airbag then connect the 30 pins adapter B40.
- Check and ensure voltage presence between plugs marked mass and +DC (+ after
contact)
Check the correct supplying of the diagnostic socket:
- supply + permanent at pin 16
- mass at pin 5
Check the continuity and insulation of the connection lines diagnostic socket / UCE airbag:
- plug 23 of UCE airbag pin 15 diagnostic socket (line L)
- plug 9 of UCE airbag pin 7 diagnostic socket (line K)
If dialogue is not established after these checking, replace UCE airbag (see chapter “UCE
airbag replacement).
