CHECK BATTERY SHORT OF HARNESS.
1) Turn ignition switch to OFF.
2) Remove console cover from console box.
3) Disconnect connector from G sensor.
4) Disconnect connector from ABSCM.
5) Turn ignition switch to ON.
6) Measure voltage between ABSCM connector and chas-
sis ground.
: Connector & terminal
(F49) No. 8 (+)—Chassis ground ( )
(F49) No. 45 (+)—Chassis ground ( )
Is voltage 0 V?
: Go to next step.
: Repair harness between ABSCM and G sensor.
7) Turn ignition switch to OFF.
8) Measure voltage between ABSCM and chassis ground.
: Connector & terminal
(F49) No. 8 (+)—Chassis ground ( )
(F49) No. 45 (+)—Chassis ground ( )
Is voltage 0 V?
: Replace ABSCM.
: Repair harness between ABSCM and chassis
ground.
