PROBLEM SYMPTOMS TABLE
Perform troubleshooting of the circuit for the applicable problem symptom in the order given in the chart be-
low. Proceed to the page located for each circuit.
HINT:

Troubleshooting of the wireless door lock control system is based on the premise that the door lock
control system and theft deterrent system are operating normally. Accordingly, before troubleshooting
the wireless door lock control system, first make certain that the door lock control system and theft de-
terrent system are operating normally.

If the instruction ºProceed to next circuit inspection shown on matrix chartº is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue the check.

If the trouble still reappears even through there are no abnormalities in any of the other circuits, check
and replace the Wireless Door Lock ECU as the last step.
