B3040 W wire failure,
communication
There is no response from
the electrojet controller after
the theft deterrent controller
sends out communication
requests.
First check whether the two failures B043 and B0422 1.
coexist. If so, first solve these two problems.
Check whether the 8-core plug of the theft deterrent 2.
controller is well connected. Check whether the wire harness
connecting the A8 pin (N wire) of the 8-core plug and
electrojet is well connected, not short circuited, and has no
poor contact. Check whether the electrojet wire harness and
the connector is well connected.
Replace the alarm (please refer to the immobilizer system 3.
component replacement). Check whether the above failures
exist. If they do not, the fault most likely exists in the alarm.
Replace the electrojet (please refer to immobilizer system 4.
component replacement). Check whether the above failures
exist. If they do not, the fault most likely exists in the
electrojet.
B3042 W wire
grounding
Short circuiting happens
between the W wire and the
ground
Check whether the theft deterrent controller's 8-core plug 1.
wire harness is touching each other.
Check whether the wire harness which connects the 8-core 2.
plug's A8 pin (W wire) and the electrojet is short circuited to
the ground.
Replace the alarm (please refer to immobilizer system 3.
component replacement). Check whether the above failures
exist. If they do not, the fault most likely exists in the alarm
Replace the electrojet (please refer to immobilizer system 4.
component replacement). Check whether the above failures
exist. If they do not, the fault most likely exists in the
electrojet.
B3043 W wire and
power is short
circuited
Short circuiting happens
between the W wire (A8
pin) and the battery positive.
Check whether the theft deterrent controller's 8-core plug 1.
wire harness is touching each other.
Check whether the wire harness which connects the 8-core 2.
plug's A8 pin (W wire) and the electrojet battery positive has
short circuited
Replace the alarm (please refer to immobilizer system 3.
component replacement). Check whether the above failures
exist. If they do not, the fault most likely exists in the alarm
Replace the electrojet (please refer to immobilizer system 4.
component replacement). Check whether the above failures
exist. If they do not, the fault most likely exists in the
electrojet.
B3045
(vehicles
without
the theft
deterrent
indicator
lamp will
show this
trouble
code, but
it will
not affect
immobilizer
system
validation.)
LED has a
short circuit or
open circuit,
LED operates
abnormally
The wire harness (A3
pin) connected to the theft
deterrent indicator (LED)
has short circuited to the
ground. The wire harness
(A3 pin) connected to
the immobilizer indicator
(LED) has an open circuit.
Check whether the theft deterrent controller's 8-core plug 1.
wire harness is touching each other.
Check whether the wire harness which connects the 8-core 2.
plug's A3 pin and the immobilizer indicator has short
circuited to the ground.
Check whether the wire harness which connects the 8-core 3.
plug's A3 pin and the immobilizer indicator has an open
circuit.
