Power Back Door System
TERMINALS OF ECU1. CHECK POWER BACK DOOR ECU
a. Disconnect the P13 and P14 connectors from the power back door ECU.
b. Measure the resistance according to the value(s) in the table.
HINT: If the result is not as specified, there may be a malfunction on the wire harness side.
c. Measure the voltage according to the value(s) in the table.
HINT: If the result is not as specified, there may be a malfunction on the wire harness side.
d. Reconnect the P13 and P14 connectors to the back door ECU.
e. Measure the voltage according to the value(s) in the table.
HINT:
- Use an oscilloscope to check the output voltages of the power back door main switch, buzzer and pulse sensor.
- If the result is not as specified, the ECU may have a malfunction.
