On Board Diagnosis

ON BOARD DIAGNOSTIC RESULTS INDICATOR LAMP
Front 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.
