CAN COMMUNICATIONPFP:23710
System DescriptionECS004VQ
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.

TROUBLE DIAGNOSES FOR SYMPTOMS
O/D OFF Indicator Lamp Does Not Come On
ECS004V2
SYMPTOM:
O/D OFF indicator lamp does not come on for about 2 seconds
when turning ignition switch to “ON”.
1. CHECK TCM POWER SOURCE
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 10, 19, 28 and ground.
3. Turn ignition switch to “OFF” position.
4. Check voltage between TCM terminal 28 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check the following items:
●Harness for short or open between ignition switch and
TCM terminals 10, 19 and 28
●Refer to AT-350, "Wiring Diagram — AT — MAIN" .
●Ignition switch and fuse. Refer to PG-2, "POWER SUPPLY ROUTING" .
2. 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.
If OK, check harness for short to ground and short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors. Refer to AT- 3 5 0 , "
Wiring Dia-
gram — AT — MAIN" .

3.CHECK LAMP CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Check resistance between TCM terminals 13 and 10, 19.
3. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG >> Check the following items:
●O/D OFF indicator lamp.
Refer to DI-10, "
Meter/Gauge Operation and Odo/Trip
Meter Segment Check in Diagnosis Mode" .
●Harness and fuse for short or open between ignition
switch and O/D OFF indicator lamp
Refer to PG-2, "
POWER SUPPLY ROUTING" .
●Harness for short or open between O/D OFF indicator lamp and TCM.
4.CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Resistance: 50 - 100Ω

1. CHECK PNP SWITCH CIRCUIT
With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage to PNP switch circuit?
Without CONSULT-II
Does self-diagnosis show damage to PNP switch circuit?
Ye s o r N o
Yes >> Check PNP switch circuit. Refer to AT- 3 4 4 , "TCM Self-
diagnosis Does Not Activate" .
No >> GO TO 2.
2. CHECK PNP SWITCH INSPECTION
Check for short or open of PNP switch harness connector terminals 1 and 2.
Refer to AT-344, "
TCM Self-diagnosis Does Not Activate" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace PNP switch.
3. CHECK CONTROL CABLE
Check control cable. Refer to AT- 4 1 6 , "
Control Cable Adjustment" .
OK or NG
OK >> GO TO 4.
NG >> Adjust control cable. Refer to AT- 4 1 6 , "
Control Cable

4. CHECK STARTING SYSTEM
Check starting system. Refer to SC-20, "
STARTING SYSTEM" .
OK or NG
OK >>INSPECTION END
