WIRING DIAGRAM
INSPECTION PROCEDURE
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
HINT: During the ACTIVE TEST, the intelligent tester sends a signal to the power back door ECU to drive the warning buzzer. If the warning buzzer operates, the warning buzzer itself and the wire harness between the warning buzzer and power back ECU are considered to be functioning normally.
OK (Power slide door ECU):
2 CHECK WIRE HARNESS (POWER BACK DOOR WARNING BUZZER WIRE HARNESS SIDE)
NOTICE: Use an oscilloscope to check the output voltages of the buzzer.

NOTICE:
4 CHECK WIRE HARNESS (POWER BACK DOOR WARNING BUZZER - POWER BACK DOOR ECU)
Resistance (Check for open circuit)
REPLACE POWER BACK DOOR ECU

DESCRIPTION
A short to GND is suspected in the CAN bus wire when the resistance between
terminals 4 (CG) and 6
(CANH), or terminals 4 (CG) and 14 (CANL) of the DLC3 is below 200 Ω.
