ENTRY AND START SYSTEM - 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.
WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.INSPECT ELECTRICAL KEY OSCILLATOR |
Disconnect the oscillator connectors.
Measure the voltage according to the value(s) in the table below.
- Standard voltage:
- Front LH side:
| Tester Connection (Symbols) | Condition | Specified Condition |
| o2-1 (+B) - o2-7 (GND) | Always | 10 to 14 V |
- Front RH side:
| Tester Connection (Symbols) | Condition | Specified Condition |
| n2-1 (+B) - n2-7 (GND) | Always | 10 to 14 V |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 2.CHECK HARNESS AND CONNECTOR (ELECTRICAL KEY OSCILLATOR - CERTIFICATION ECU) |
Disconnect the P33 ECU connector.
- Standard resistance:
| Tester Connection (Symbols) | Condition | Specified Condition |
| P33-33 (CLG1) - o2-10 (CLG) | Always | Below 1 Ω |
| P33-34 (CG1B) - o2-5 (CLGB) | Always | Below 1 Ω |
| P33-35 (CLG2) - n2-10 (CLG) | Always | Below 1 Ω |
| P33-36 (CG2B) - n2-5 (CLGB) | Always | Below 1 Ω |
| P33-33 (CLG1) - Body ground | Always | 10 kΩ or higher |
| P33-34 (CG1B) - Body ground | Always | 10 kΩ or higher |
| P33-35 (CLG2) - Body ground | Always | 10 kΩ or higher |
| P33-36 (CG2B) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 3.CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR (CHECK OPERATION OF OSCILLATOR) |
Replace the door oscillator.
Check that the entry LOCK / UNLOCK function operates normally.
- OK:
- Entry LOCK / UNLOCK function operates normally.
| | END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE) |
|
|
| 4.PERFORM ACTIVE TEST BY INTELLIGENT TESTER (CERTIFICATION ECU OUTPUT SIGNAL) |
Reconnect the ECU and the oscillator connectors.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Following the display on the tester, select the "ACTIVE TEST".
SMART KEY (Certification ECU):| Item | Vehicle Condition/Test Details |
| D Transmitter | Door Oscillator ON / OFF |
| P Transmitter | Door Oscillator ON / OFF |
Measure the frequency according to the value(s) in the table below.
- Standard:
| Tester Connection (Symbols) | Condition | Specified condition |
| P33-33 (CLG1) - P33-34 (CG1B) | During ACTIVE TEST | Frequency is generated (higher than 0 Hz) |
| P33-35 (CLG2) - P33-36 (CG2B) | During ACTIVE TEST | Frequency is generated (higher than 0 Hz) |
| | REPLACE CERTIFICATION ECU |
|
|
| OK | |
| |
| PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE |
