ACTIVE TEST
Display Item List

On Board Diagnosis

AIS001HE

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

DIAGNOSIS ITEM

Test item

Description

Diagnosis item

Description

Communication diagnosis

It can check the communication line between BCM and each LCU, and also each LCU, 
for a communication error 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 positioner

Diagnoses 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.

GW-100

REVERSE INTERLOCK DOOR MIRROR SYSTEM

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 self–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.

Trouble Diagnosis Chart

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
irreproducible 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 diagnosis result indication start without no diagnosis cancel operation.
