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 
Perform 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.

On Board Diagnosis

ON BOARD DIAGNOSTIC RESULTS INDICATOR LAMP

●

Map lamps and step lamps (all seats) act as the indicators for the on board diagnosis.

DIAGNOSIS ITEM

COMMUNICATION DIAGNOSIS

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

How To Perform Communication Diagnosis

Description

In this mode, a malfunction code is indicated by the number of flashes from the map lamps and step lamps as
shown below:

After indicator lamp turns on for 2 seconds then off for 2 seconds, it flashes [cycling ON (0.5 sec.)/OFF (0.5
sec.)] to indicate a malfunction code of the first digit. Then, 1.5 second after indicator lamp turns off, it again
flashes [cycling ON (0.5 sec.)/OFF (0.5 sec.)] to indicate a malfunction code of the second digit.
For example, the indicator lamp goes on and off for 0.5 seconds twice and after 1.5 seconds, it goes on and off
for 0.5 seconds four times. This indicates malfunction code of driver door control unit communication.
