Year of Manufacture *: 2000
( Optional ) Engine Code or CC: 1700DTH
Haven't work on an SAB6 fault for a while but have a curious one in now that I would like a little advice on.
Fault:
Airbag MIL ON (comes on after 10 seconds after initially going out as normal)
Codes:
Scanned ECU using Autodiagnos and Solus Ultra - NO CODES FOUND!!!
Live Data - Autodiagnos only
1. Squibs/pretensioners all 0.0ohms
2. System voltage good - 14.3 as reported by airbag ECU....although it has a line underneath saying 'System Voltage Fault'
3. MIL ON
Although data is displayed it isn't valid other than MIL and voltage.
Tests:
WIGGLE TEST!!!!
Supply and grounds good at either side of ECU. pins. Wiring to squibs and pretensioners all good.
Disconnecting any of the airbag components also makes no difference to displayed readings.
Occasionally what will happen is that the 'System Voltage Fault' disappears, the component resistance values will become more realistic although the ECU does not see the components disconnected still.
Disconnecting and reconnecting the unit does not have any effect on the fault neither does forcing a code reset.
I am convinced that the ECU is at fault but was curious as to anybody else having seen a similar/same fault???
Many thanks,
Andrew
