Airbag warning lamp 2 (central warning
lamp), (MIU 2)
|
The central warning lamp does not light up when the ignition switch is turned to
the Drive position.
|
Note
|
|
If a fault occurs in the wiring between the airbag control module and the main
instrument display panel, diagnostic trouble code B1232 or B1233 will be generated in the
airbag system.
|
|
1.
|
Check whether diagnostic
trouble code B1232 or B1233 is present in the airbag system. If diagnostic troubles are
present, continue fault diagnosis as described in "Airbag" M1994
or
8:6 "SRS (airbag)" M1995.
|
|
2.
|
If new trouble codes are generated, connect a BOB to the main instrument
display panel's connector.
|
|
3.
|
Check the operation of the central warning lamp by switching on the ignition and
waiting until the lamp goes out (provided that there are no other faults in the car which could
cause the lamp to remain alight).
Then ground pin 2 on the BOB.
If the main instrument display panel is OK, the central warning lamp should light up.
If it does not, the fault is in the processor card. Continue on
.

Important
|
|
A diagnostic trouble code could be generated in the airbag system when pin 2 is
grounded, causing the SRS 1 lamp to start flashing. If this happens, clear the trouble code.
