Statuses and
ParametersET073:Computer locked
by toolYES or NO
This status indicates whether or not
the computer is locked.In the event of a fault, apply the
interpretation for DF034
"Computer locked".
ET143:Passenger
airbag(s) lockedYES or NO
This status indicates the locking of
the passenger trigger lines
(passenger front airbag, passenger
chest-level airbag).In the event of a fault, apply the
interpretation of DF193
"Passenger airbag locking
status change".
ET076:Computer to be
replacedYES or NO
This status indicates whether the
computer should be replaced or not.In the event of a fault, apply the
interpretation of DF001
"Computer" and DF194
"Computer to be replaced
following impact".
ET010: Impact detectedYES or NO
This status indicates whether an
impact has been detected by the
computer.In the event of a fault, apply the
interpretation of DF194 "Computer
to be replaced following impact".
ET074:Fault warning
light activatedYES or NO
This status permits a check on the
request by the computer for the
"airbag fault" indicator light to be lit
or not.In the event of a fault, apply the
interpretation of DF165 "Airbag
fault warning light circuit".
ET072:Passenger airbag
status indicator
light commandedYES or NO
This status permits a check on the
request by the computer for the
"passenger airbag" indicator light
to be lit.In the event of a fault, apply the
interpretation of DF028
"Passenger airbag status
indicator light circuit".
PR001:Computer feed
voltageThis parameter indicates the
computer voltage.
The voltage should
be between:
9 V < X < 14 VIn the event of a fault, apply the
interpretation for DF038
"Computer".
ET169:Driver's seat belt
contactOPEN - CLOSED - FAULTY
This status is used to check whether
the driver buckle switch is working
properly.In the event of a fault, apply the
interpretation of DF232 "Driver's
seat belt buckle sensor circuit".

TriggeringPR013:Driver's front airbag
resistance
The resistance should be
between:
1.2 Ω < X < 5.8 Ω
This value may be 99.9 Ω if
the vehicle is not fitted with
the airbag in question
(see vehicle equipment).
These parameters indicate
the impedance in ohms on
trigger lines.In the event of a fault, apply the
interpretation of DF003 "Driver's front
airbag circuit".
PR014:Passenger front
airbag resistanceIn the event of a fault, apply the
interpretation of DF004 "Passenger
front airbag circuit".
PR011:Driver's side airbag
resistanceIn the event of a fault, apply the
interpretation of DF077 "Driver's front
chest-level side airbag circuit"
.
PR012:Passenger side
airbag resistanceIn the event of a fault, apply the
interpretation of DF068 "Passenger
front chest-level side airbag circuit"
.
PR017:Driver's side
curtain airbag
resistanceIn the event of a fault, apply the
interpretation of DF070 "Driver's side
curtain airbag circuit".
PR018:Passenger side
curtain airbag
resistanceIn the event of a fault, apply the
interpretation of DF069 "Passenger
side curtain airbag circuit".
PR015:Driver’s
pretensioner
resistanceIn the event of a fault, apply the
interpretation of DF183 "Driver's
buckle pretensioner circuit"
.
PR016:Passenger
pretensioner
resistanceIn the event of a fault, apply the

Lock AirbagsET073:Computer locked
by toolYES or NO
This status indicates whether or
not the computer is locked.In the event of a fault, apply the
interpretation of DF034 "Computer
locked".
ET143:Passenger
airbag(s) lockedYES or NO
This status indicates the locking
of the passenger trigger lines
(passenger front airbag,
passenger chest-level airbag,
if fitted).In the event of a fault, apply the
interpretation of DF193 "Change of
passenger airbag locking status"
and DF091 "Airbag locking switch
circuit".
ET103:Type of
passenger airbag
lockingYES or NO
This status indicates the
inhibited trigger lines when the
passenger airbag is inhibited
(passenger front airbag,
passenger front chest-level
airbag, if fitted).In the event of a fault, apply the
interpretation of DF091 "Airbag
locking switch circuit " then DF193
"Change of passenger airbag
locking status".
ET169:Driver's seat belt
contactOPEN - CLOSED - FAULTY
This status is used to check
whether the driver buckle switch
is working properly.In the event of a fault, apply the
interpretation of DF232 "Driver's seat
belt buckle sensor circuit".
PR147:Airbag locking
circuit
impedance380 Ω +/- 40 Ω, this resistance
indicates that the passenger
airbag locking switch is "ON".
or
90 Ω +/- 10 Ω, this resistance
indicates that the passenger
airbag locking switch is "OFF"In the event of a fault, apply the
interpretation of DF091 "Airbag
locking switch circuit " then DF193
"Change of passenger airbag
locking status".
