DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
• Turn power switch OFF and wait at least 90 seconds.
CAUTION:
During this period, never perform vehicle handling such as opening and closing of doors. If some
kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the
vehicle handling.
• Make sure that 12V battery voltage is 11 V or more.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1. Turn power switch ON and wait at least 1 second.
2. Check self-diagnostic result.
Is DTC detected?
YES
>> Proceed to
EVC-217, "Diagnosis Procedure"
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000010120671
1.
CHECK VCM GROUND CIRCUIT
1. Turn power switch OFF.
2. Disconnect VCM harness connector.
3. Check the continuity between VCM harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace error-detected parts.
2.
CHECK ACCELERATOR PEDAL POSITION (APP) SENSOR SIGNAL CIRCUIT
1. Disconnect APP sensor harness connector.
2. Check the continuity between APP sensor harness connector terminals.

P3100 EV SYSTEM CAN COMMUNICATION
Description
INFOID:0000000010120673
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.
