Fault remedy
– -N276- Check.
⇒ P age 391
– Check electrical con-
nection to pressure
regulating valve.
Check terminal 15 ON
and +12V on actuator
+ (A2). No voltage ->
open circuit between
Vbat and actuator.
Pull connector off ac-
tuator, and check wir-
ing between actuator/
ECU. Measure resist-
ance on actuator. If no
continuity -> renew
ECU
– -N276- Check.
⇒ P age 391
Pull connector off actua-
tor, and read event mem-
ory again -- if in addition
PCVOL--> renew actua-
tor -- otherwise check
wiring between actuator/
ECU -- if OK --> renew
ECU
– -N276- Check.
⇒ P age 391
– Pull connector off ac-
tuator, and read event
memory again -- if in
addition PCVOL--> re-
new actuator -- other-
wise check wiring be-
tween actuator/ECU --
if OK --> renew ECU
