On Board Diagnosis

NIS0012O

BCM can check each local unit (LCU), switches, loads, and malfunctions in communication with the self-diag-
nosis.

DIAGNOSIS ITEM

COMMUNICATION DIAGNOSIS

Check the communication between BCM and each local control unit (LCU).

Operation Procedure

Diagnosis Result Display

●

The indicator lamps (the map lamp and step lamp) turn ON (illuminate) for 2 seconds and OFF (go off) for
2 seconds to indicate that the diagnosis has started, then indicate the diagnosis trouble code.

●

To indicate the diagnosis trouble code, the indicator lamps illuminate or flash.

●

At first, the lamps indicate the second place by ON/OFF with 0.5 second-interval, then OFF for 1.5 sec-
onds. Next, they indicate the first place by ON/OFF with 0.5 second interval.

●

If there are multiple malfunctioning parts, the lamps indicate them in sequence from the smallest diagno-
sis trouble code.

●

The diagnosis results repeat until the diagnosis is cancelled.

●

If a malfunction is indicated, carry out the communication diagnosis again to check that the same diagno-
sis trouble code is indicated.

Diagnosis item

Description

Communication diagnosis

It can check the communication line between BCM and each LCU, and also each LCU, for a
communication malfunction.

Switch monitor

It can check the switch systems which send data to BCM and each LCU for a malfunction.

Self-diagnosis for auto drive
positioner

Diagnosis malfunctions in each motor and sensor in the electrical load parts of the driver power seat
system (sliding, reclining, and lifter [front/rear]), of the steering wheel system (tilt, telescoping), and of
door mirror.
