| Power Back Door cannot be Operated Using Kick Sensor |
DESCRIPTION
Signals from the kick door control sensor are sent to the multiplex network door ECU. If the power back door system does not operate, there may be a malfunction in the kick door control sensor circuit.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Before troubleshooting, make sure that the "Kick Sensor Function" customize setting is set to "ON".
Before troubleshooting, be sure to read Precautions for Touchless Power Back Door.
If the multiplex network door ECU has been removed and installed or replaced, or if any of the connectors has been disconnected, initialize the power back door system.
After performing work, using the GTS, read the Data List item "Kick Sensor Connection" and check that the kick door control sensor is connected.
