Can Communication Line Control
WARNING: This page is about a different car, the 2002 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
With CAN communication, by connecting each control unit using 2 communication lines (CAN L-line, CAN H-line), it is possible to transmit maximum amount of information with minimum wiring. Each control unit can transmit and receive data, and read necessary information only.
- Fail-Safe Control
- When CAN communication with other control units is impossible, IPDM performs fail-safe control. After CAN communication recovers normally, it also returns to normal control.
- Operation of control parts by IPDM during fail-safe mode is shown in Fig 1
