CAN CAMMUNICATION LINEPFP:31940
DescriptionECS004UJ
CAN (Control Area Network) is a serial communication line for real time application. It is an on-vehicle multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tonic 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.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
*: This terminal is connected to the ECM.
On Board Diagnosis LogicECS004UK
** : A/T COMM LINE means CAN communication line.
Self-Diagnosis Code Confirmation ProcedureECS0 04 UL
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Wait at least 6 seconds or start engine and wait for at least 6
seconds.
WITHOUT CONSULT-II
1. Turn ignition switch “ON”.
2. Wait at least 6 seconds or start engine and wait at least 6 sec-
onds.
3. Perform self-diagnosis.
Refer to SELF-DIAGNOSTIC PROCEDURE (NO TOOLS),
