On Board Diagnosis

AIS001JU

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.

SEAT SLIDE

The sliding motor is activated by receiving the drive signal.

SEAT RECLINING

The reclining motor is activated by receiving the drive signal.

SEAT LIFTER FR

The front end lifter motor is activated by receiving the drive signal.

SEAT LIFTER RR

The rear end lifter motor is activated by receiving the drive signal.

MEMORY SW INDCTR

The memory switch indicator is lit by receiving the drive signal.

MIRROR MOTOR RH

The RH mirror motor moves the mirror UP/DOWN and LEFT/RIGHT by receiving the drive 
signal.

MIRROR MOTOR LH

The LH mirror motor moves the mirror UP/DOWN and LEFT/RIGHT by receiving the drive 
signal.

Diagnosis item

Description

Communication diagnosis

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

Switch monitor

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

Self-diagnosis for auto drive posi-
tioner

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.

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.

NOTE:

For a specific local control unit (LCU), either "PAST COMM DATA" or "PAST NO RESPONSE" may be displayed instead of the
above results. This is caused by the data record, so erase the records.
(The display only shows the incident records, they are not malfunctions caused during the diagnosis. One possible cause is that an
reproducible incident occurred.)

Follow the steps below to erase the memory. 
Carry out either disconnect BCM battery power supply or erase memory with CONSULT-II.

With the battery connected, if the local control unit (LCU) connector is disconnected and left for approximately 1 minute, the BCM
stores "NO RESPONSE" record.

Cancel of Communication Diagnosis

If one of the following conditions is satisfied, the communication diagnosis is cancelled.

When the ignition switch is turned OFF.

The vehicle speed becomes 7 km/h (4 MPH) or higher.

Ten minutes have passed since the diagnostic result indication start without no diagnosis cancel opera-
tion.

COMMUNICATION SYSTEM A

1. 

CHECK BCM

Replace the BCM with a known-good one, and carry out the communication diagnosis. Refer to 

SE-46, "COM-

MUNICATION DIAGNOSIS"

 .

OK or NG

OK

>> Replace BCM.

NG

>> GO TO 2.

2. 

CHECK LCU

1.

Replace with the previously installed BCM.

2.

Replace the LCU with a known-good one, and carry out the communication diagnosis. Refer to 

SE-46,

"COMMUNICATION DIAGNOSIS"

 .

OK or NG

OK

>> Replace LCU.

NG

>> Repair the harness between the LCU and BCM.

COMMUNICATION SYSTEM B

1. 

CHECK HARNESS CONNECTOR

Check terminals (at the control unit and harness) on the malfunctioning LCU for disconnection, bend, poor
connection and other malfunctions.

OK or NG

OK

>> GO TO 2.

NG

>> Repair the terminals and connectors.
