DTC 97

CIRCUIT DIAGRAM





INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
The Electronic Brake Control Module (EBCM) provides power (5 volts) and ground to the G sensor through CKT "O" (or "O" & "Y/G") and CKT "O/W" respectively. The G sensor converts the change in vehicle motion, or inertia, into a voltage signal. This signal which is sent to the EBCM through CKT "O/B".
The G sensor provides additional vehicle speed reference to the EBCM which is needed when the vehicle is in four-wheel-drive mode. The voltage signal ranges, from 2.5 volts at zero speed change (or constant motion), to about 0 volts under heavy acceleration, to near 5 volts under heavy braking.

FAILURE CONDITION:
DTC 97 can be-set anytime when the EBCM detects a short to ground in CKT "O/W", EBCM connector E124, terminal "2" and G sensor connector terminal "2".
