Door Oscillator Circuit
DOOR LOCK: SMART ACCESS SYSTEM WITH PUSH-BUTTON START: Door Oscillator Circuit
- Door Oscillator Circuit
DESCRIPTION
Door oscillators are built into each door. Each of them forms its own action area around its door and detects the presence of the electrical key.

INSPECTION PROCEDURE
PROCEDURE
1. INSPECT ELECTRICAL KEY OSCILLATOR
(a) Disconnect the oscillator connectors.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
Front LH side
Front RH side
Rear LH side
Rear RH side
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (ELECTRICAL KEY OSCILLATOR - CERTIFICATION ECU)
(a) Disconnect the E13 and E14 ECU connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
Front LH side
Front RH side
Rear LH side
Rear RH side
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR (CHECK OPERATION OF OSCILLATOR)
(a) Replace the door oscillator.
(b) Check that the entry LOCK/UNLOCK function operates normally.
OK:
Entry LOCK/UNLOCK function operates normally.
OK -- END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE)
NG -- Continue to next step.
4. PERFORM ACTIVE TEST USING TECHSTREAM (CERTIFICATION ECU OUTPUT SIGNAL)
(a) Reconnect the ECU and the oscillator 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:
Front LH side
Front RH side
Rear LH side
Rear RH side
NG -- REPLACE CERTIFICATION ECU
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
