900 SE Hatchback L4-1985cc 2.0L DOHC Turbo EFI (1997)
The control module stores up to five different diagnostic trouble codes plus diagnostic trouble code B1615 (detonator circuit activated). Further
diagnostic trouble codes are not registered.
When the feed voltage is cut it takes a maximum of 5 seconds for the processor to disconnect the energy reserve from the detonator circuits.
The control module is of disposable type, and if it has activated the airbags it cannot be reused. If this has happened, the SRS lamp lights. Diagnostic
trouble codes can be read after the airbags have detonated, but cannot be erased.
Control Module Voltage Feed
When the ignition key is in the drive position, the control module is supplied with +15 volts via fuse 4 to pin 5. The control module is specified to
work with a voltage supply between 7 and 16 volts.
Connector
The control module connector is equipped with 5 short-circuiting straps which, in pairs, short-circuit the leads to the tour detonators and between the
warning lamp lead and ground.
Diagnostics with ISAT
Communication with the ISAT is via pin 9. The data link connector is located under the passenger seat.
