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 a malfunctioning oscillator.

INSPECTION PROCEDURE

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

1. Disconnect the P33 ECU connector.

2. Disconnect the oscillator connectors.

Standard resistance:

Tester Connection (Symbols)	Condition	Specified Condition
P33-16 (CG7B) - Q48-3 (CLGB)	Always	Below 1 Ω
P33-15 (CLG7) - Q48-1 (CLG6)	Always	Below 1 Ω
P33-32 (CG8B) - P31-2 (CLGB)	Always	Below 1 Ω
P33-31 (CLG8) - P32-1 (CLG5)	Always	Below 1 Ω
P33-16 (CB7B) - Body ground	Always	10 kΩ or higher
P33-15 (CLG7) - Body ground	Always	10 kΩ or higher
P33-32 (CG8B) - Body ground	Always	10 kΩ or higher
P33-31 (CLG8) - Body ground	Always	10 kΩ or higher

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK

2. CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR

1. Replace the electrical key oscillator.

2. 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

3. PERFORM ACTIVE TEST BY INTELLIGENT TESTER

1. Reconnect the oscillator and the ECU connectors.

2. Connect the intelligent tester to the DLC3.

3. Turn the engine switch on (IG).

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

   SMART KEY (Certification ECU): 

   Item	Vehicle Condition/Test Details
   In Bdr Transmitter	Electrical key oscillator (Luggage compartment Inner) ON / OFF
   Bdoor Transmitter	Electrical key oscillator (Luggage compartment outer) ON / OFF

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

   Standard:

   Tester Connection (Symbols)	Condition	Specified Condition
   P33-16 (CG7B) - P33-15 (CLG7)	During ACTIVE TEST	Frequency is generated (higher than 0 Hz)
   P33-32 (CG8B) - P33-31 (CLG8)	During ACTIVE TEST	Frequency is generated (higher than 0 Hz)

NG	REPLACE CERTIFICATION ECU

OK
