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 problem, check both the inner and outer luggage compartment oscillator circuits.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU - ELECTRICAL KEY OSCILLATOR)




(a) Disconnect the E13 ECU connector.
(b) Disconnect the oscillator connectors.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
Inside Luggage Compartment





Outside Luggage Compartment





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR
(a) Replace the electrical key oscillator.
(b) Check that the luggage compartment door entry LOCK/UNLOCK function operates normally.
OK:
Luggage compartment door entry LOCK/UNLOCK function operates normally.
OK -- END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE)
NG -- Continue to next step.
3. PERFORM ACTIVE TEST USING TECHSTREAM (CERTIFICATION ECU OUTPUT SIGNAL)
(a) Reconnect the oscillator and the ECU connectors.
(b) Connect Techstream to the DLC3.
(c) Turn the engine switch on (IG).
(d) Turn the tester on.
(e) Enter the following menus: Body Electrical / Smart Access / Active Test.
(f) Perform the Active Test according to the display on the tester.

Smart Access:








(g) Measure the frequency according to the value(s) in the table below.
Standard:
Inside Luggage Compartment





Outside Luggage Compartment





NG -- REPLACE CERTIFICATION ECU
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
