DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Turn the ignition switch ON.
2. Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is DTC
“C1145” or “C1146” detected?
YES >> Proceed to diagnosis procedure. Refer to BRC-113, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766968
CAUTION:
 Sudden turns (such as spin turns, acceleration turns), drifting, etc., when VDC function is off (VDC
OFF switch “ON”) may cause yaw rate/side G sensor system to indicate a malfunction. However, this
is not a malfunction, if normal operation can be resumed after restarting engine. Then erase memory
of self-diagnosis.
 If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF indica-
tor lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system mal-
function. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn-table or other moving surface, and start the engine. Results will return to normal.
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Disconnect yaw rate/side G sensor connector.
4. Check terminal for deformation, disconnection, looseness, etc.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK YAW RATE/SIDE G SENSOR POWER SUPPLY CIRCUIT
1. Turn the ignition switch ON.
CAUTION:
Never start the engine.
2. Check the voltage between yaw rate/side G sensor harness connector and ground.
3. Turn the ignition switch OFF.
4. Check the voltage between yaw rate/side G sensor harness connector and ground.

U1000, U1002 CAN COMM CIRCUIT
DescriptionINFOID:0000000003766990
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
