CAN COMMUNICATIONPFP:23710
System DescriptionECS007QX
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.

3. DETECT MALFUNCTIONING ITEM
Check the following items:
●Harness for short or open between ignition switch and TCM terminals 10, 19 and 28
●Fuse
●Ignition switch
Refer to EL-11,"POWER SUPPLY ROUTING".
OK or NG
OK >> GO TO 4
NG >> Repair or replace damaged parts.
4. CHECK TCM GROUND CIRCUIT
1. Turn ignition switch to OFF position.
2. Disconnect TCM harness connector.
3. Check continuity between TCM terminals 25, 48 and ground. Refer to AT- 3 4 0 , "
Wiring Diagram — AT —
MAIN" .
If OK, check harness for short to ground and short to power.
OK or NG
OK >>INSPECTION END
NG >> Repair open circuit or short to ground or short to power in harness or connectors. Continuity should exist.
