P RESENT 1. DEF Open circuit or short-circuit
RECOMMEND AT IONS Check with the contact set on, the parame ter “PR004: computer
su pp lying voltage” ( measur ed voltage at battery: about 12 volts).
- if at limit the value is of 16 volts, it means there is a short-circuit at
mass.
- if at limit the value is of 10.7 volts, it means there is short-circuit at
+ 12 volts of one one of th e supply ways +5 volts
Ch eck the connection and condition of the connectors of the valve potentiometer, manifold pressure
s ensor and refrigerant fluid pressure transduc er 9if the re is on the vehicle ).
R eplace the connector/c onnectors if necessary.
Disc onne c t one by one, the following transduc e rs, if they a re passing from sta te prese nt to
me mo rized: valve potentiometer, manifold pressure transduc er and refrigerant fluid pressure
t ransducer (if there is on vehicle).
Treat the failure from the transducer, if necessary.
Check the insu lation ,continuity and the absence of the parasite resistance on lines:
Pin 74 injection computer > pin B valve potenti ometer
Pin 78 injection computer > pin C manifold pressure transducer
Pin 83 injection computer > pin B refrige rant fluid pressure transducer (if there is).
M end if necessary.
If the problem is persisting after these checking, treat the others failures then perform the conformity
checking.
Pe rform the operations from “recommendations” for reparation confirma tion
AF TER Fix any other possible failures
REPARATION Erase the failures memoriz ed by the injection computer.
Perform a conformity checking by means of the CLIP tester.
