Function
The Airbag Control Module -J234- is located
behind the console on the center tunnel. It is
equipped with a Diagnostic Trouble Code (DTC)
Memory. The Data Link Connectors (DLCs) are
located to the right of the ignition switch.
The Airbag Control Module -J234- detects
malfunctions in the airbag system and stores
them in a permanent memory.
After the ignition is switched on, the Airbag
Malfunction Indicator Lamp (MIL) -K75- comes
on for about 4 seconds and then goes out again.
If the MIL continues to blink for additional 12
seconds it signals that the passenger airbag is
disconnected.
If the MIL -K75- does not go out after about 4
seconds, the supply voltage (B+) for the Airbag
Control Module -J234- is faulty. CheckDTC
memory Page 01-25
If the MIL -K75- comes on again then a
malfunction exists. CheckDTC memory
01-25 .
If the MIL continues to blink, replace Control
Module -J234-.
