Mitsubishi Outlander: Local Interconnect Network (LIN)

General Information

LIN refers to "Local Interconnect Network," which is a serial multiplex communication protocol* administrated by LIN consortium. A communication circuit employing the LIN protocol connects each ECU, and switch and sensor data can be shared among ECUs, which enables more reduction in wiring.

NOTE: *: The regulations that have been decided in detail, from software matters such as the necessary transmission rate for communication, the system, data format, and communication timing control method to hardware matters such as the harness type and length and the resistance values.

STRUCTURE

Mitsubishi Outlander. Local Interconnect Network (LIN)

Master and slave ECUs are connected to the LIN bus lines. The master ECU is the ETACS*1-ECU, and the slave ECUs are the column switch (column- ECU), the sunroof motor assembly (sunroof- ECU)*2, the lighting control sensor*3, the power window main switch, the theft-alarm siren (via LIN cutoff control unit*4)*5 and the theft-alarm siren*5.

The master ECU requests these slave ECUs to communicate each other via communication lines.

DIAGNOSIS PROCEDURE

STEP 1. Check ETACS-ECU connectors C-316 and C-317 and theft-alarm sensor connector D-136 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are ETACS-ECU connectors C-316 and C-317 and theft-alarm sensor connector D-136 in good condition?

YES : Go to Step 2.

NO : Repair or replace the damaged component(s). Go to Step 7.

STEP 2. Check the ground circuit to the theft-alarm sensor.

Measure the resistance at theft-alarm sensor connector D-136.

Mitsubishi Outlander. Local Interconnect Network (LIN)

(1) Disconnect theft-alarm sensor connector D-136 and measure the resistance available at the wiring harness side of the connector.
