CHECK G SENSOR.
1) Remove G sensor from vehicle.
2) Connect connector to G sensor.
3) Connect connector to ABSCM.
4) Turn ignition switch to ON.
5) Measure voltage between G sensor connector termi-
nals.

CHECK ABSCM.
1) Connect all connectors.
2) Erase the memory.
3) Perform inspection mode.
4) Read out the trouble code.
: Is the same trouble code as in the current
diagnosis still being output?
: Replace ABSCM.
: Go to next.
: Are other trouble codes being output?
: Proceed with the diagnosis corresponding to the
trouble code.
: A temporary poor contact.
