Inspection Procedure

PERFORM ACTIVE TEST BY INTELLIGENT TESTER (CERTIFICATION ECU - OUTPUT SIGNAL)

Connect the intelligent tester to the DLC3.
Engine switch ON (IG).

Following the display on the tester, select the "ACTIVE TEST".

Certification ECU:

ECU CERTIFICATION REFERENCE

Item	Vehicle Condition / Test Details
IN-BDR TRNSMTTR	Luggage compartment oscillator (Inner) ON / OFF
BDOOR TRNSMTTR	Luggage compartment oscillator (Outer) ON / OFF

Measure the frequency according to the value(s) in the table below.

3. Measure the resistance between the oscillator and the certification ECU to check for an open circuit in the wire harness.
  Resistance:
  
  Below 1 Ω
4. Measure the resistance between the oscillator and the certification ECU to check for an short circuit in the wire harness.
  Resistance:
  
  10 kΩ or higher
  
  HINT:
  
  Refer to the wiring diagram for connection of each terminal.
