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 seconds 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 control unit communication.

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.)
●
