U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000005931248
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 s
peed 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 CA N 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 communicate data but selectively reads required data only.

• Turn ON when there is a malfunction in EPS system. If indicates that fail-safe mode is engaged and enters a
manual steering state (Control turning force steering wheel becomes heavy).
• Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF after the engine
starts, if system is normal.
EPS WARNING LAMP INDICATION
CAUTION:
EPS warning lamp also turns ON due to data reception error, CAN communication error etc.
Component Function CheckINFOID:0000000005931252

Check that the EPS warning lamp turns ON when igni tion switch turns ON. Then, EPS warning lamp turns
OFF after the engine is started.
Is the inspection result normal?
YES >> Inspection End
NO >> Perform trouble diagnosis. Refer to STC-19, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005931253
1.PERFORM SELF-DIAGNOSIS
With CONSULT-III
1. Turn the ignition switch OFF to ON.
2. Perform EPS control unit self-diagnosis.
Is any DTC detected?
YES >> Check the DTC. Refer to STC-24, "DTC Index".

2.CHECK EPS WARNING LAMP SIGNAL
With CONSULT-III
1. Turn the ignition switch ON. CAUTION:
Never start the engine.
2. On “DATA MONITOR”, select “WARNING LAMP”.
3. Check that the EPS warning lamp is turned ON.
4. Start the engine. CAUTION:
Stop the vehicle.
5. Check that the EPS warning lamp is turned OFF.
Is the inspection result normal?
YES >> Perform the trouble diagnosis for combinat ion meter power supply circuit. Refer to DI-15, "Power
Supply and Ground Circuit Inspection".
NO >> Replace the EPS control unit. Refer to PS-10, "
Removal and Installation".
