Continuation:
(Second)
There is an open circuit in one of the
supply wires for the sensor for
transverse acceleration -G200-.
Electrical Wiring Diagrams, Troubleshooting &
Component Locations - Check Ground (GND) between sensor for
transverse acceleration -G200 (terminal 1) and
ABS control module -J104- (terminal 69).
- Check voltage supply between sensor for
transverse acceleration -G200 (terminal 3) and -
J104- ABS control module (terminal 67).
