Luggage Oscillator Circuit

DOOR LOCK: SMART KEY SYSTEM: Luggage Oscillator Circuit
- Luggage Oscillator Circuit

DESCRIPTION

The certification ECU activates the inner and outer luggage compartment oscillators. The power is supplied from the certification ECU to both the inner and outer luggage compartment oscillators. The inner and outer luggage compartment oscillator circuits have the same wiring. If the entry luggage compartment function has a malfunction, check the circuit for the malfunctioning oscillator.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (CERTIFICATION ECU - OUTPUT SIGNAL)

(a) Connect Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the tester on.

(d) Enter the following menus: Body Electrical / Smart Key / Active Test.

(e) Perform the Active Test according to the display on the tester.

Smart Key:





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





OK:





NG -- REPLACE CERTIFICATION ECU
OK -- Continue to next step.

2. CHECK WIRE HARNESS (CERTIFICATION ECU - LUGGAGE COMPARTMENT OSCILLATOR)

(a) Disconnect the D39 ECU connector.





(b) Disconnect the oscillator connectors.





(c) Measure the resistance between the oscillator and the certification ECU to check for an open circuit in the wire harness.





Resistance:

Below 1 Ohms

(d) Measure the resistance between the oscillator and the certification ECU to check for an short circuit in the wire harness.

Resistance:

10 kOhms or higher

HINT
Refer to the wiring diagram for connection of each terminal.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
