| Lost communication with vehicle dynamics control module And |
|
2005 disco3
From one dayto the other i had a lot of faults.
Charged battery and cleared faults.
Disconnected and reconnected connectors behind the battery and to the abs.
These faults remain
Using IIDTool BT V3.0 B2803
Body Control
B1C57-14 (2F) Passive start ignition relay coil circuit - General electrical failure - circuit short to ground or open
( at 60 km )
Navigation
U2005-31 (2F) Vehicle speed - Frequency modulation/pulse width modulation failure - no signal
( at 146437 km )
Transfer Case
U0122-87 (2F) Lost communication with vehicle dynamics control module - Bus signal/message failure - missing a message
( at 343042 km )
Transmission
P0500-00 (2F) Vehicle speed sensor A
( at 343042 km )
Ventilation
B1B78-84 (2F) System pressure - Bus signal/message failure - signal is below allowable range
( at 343042 km )
Which is vehicle speed sensor a?
Where els to start?
Thanks

Managed to see the individual wheel sensor speeds and front left was 0.
I measured resistance on the sensor and a new sensor and both were around 500-600ohm. I plugged the sensor in, hanging in free air and the errors disappeared.
I installed the new sensor and all is good.
