U1000 CAN COMM CIRCUIT
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.

Transmitter Wake Up OperationINFOID:0000000005931106
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Turn ignition switch ON. Push the transmitter activation tool against the tire near the front left transmitter. Press the button for
5 seconds. The hazard warning lamps flash per the diagram
below.
2. Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends flashing indicator status by CAN according to the following time chart.
4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

How to Perform Trouble Diagnosis for Quick and Accurate RepairINFOID:0000000005931108
INTRODUCTION
• Before troubleshooting, verify customer complaints.
• If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal- functioning. Hold and shake these parts to make sure they are securely connected.
• When using a circuit tester to measure voltage or re sistance of each circuit, be careful not to damage or
deform connector terminals.
WORK FLOW
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
SELF DIAGNOSTIC RESULT Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read. ECU IDENTIFICATION BCM part number can be read.
