Front Passenger Side Door Entry Unlock Function Does Not Operate

DOOR LOCK: SMART KEY SYSTEM: Front Passenger Side Door Entry Unlock Function does not Operate

Front Passenger Side Door Entry Unlock Function does not Operate

DESCRIPTION

When an ID code from the door electrical key oscillator RH matches an ID code from the key, the certification ECU outputs a SEL2 signal (Lo when output) to the door electrical key oscillator RH, activates the touch sensor inside the outside door handle, and enters unlock standby condition. When the touch sensor is touched, the door electrical key oscillator sends a SENS signal (Lo when output) to the certification ECU and the certification ECU sends an unlock signal to each door lock.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK MANUAL DOOR UNLOCK OPERATION
(a) Check that the manual door lock and unlock function operates normally.
OK:
Manual door lock and unlock function operates normally.
NG -- GO TO POWER DOOR LOCK CONTROL SYSTEM
OK -- Continue to next step.

2. CHECK DOOR ELECTRICAL KEY OSCILLATOR RH (SEL VOLTAGE)




(a) Measure the voltage between the terminals of the connector when the key is operated.
Standard voltage:






NG -- CHECK WIRE HARNESS (DOOR ELECTRICAL KEY OSCILLATOR RH - CERTIFICATION ECU)
OK -- Continue to next step.

3. CHECK DOOR ELECTRICAL KEY OSCILLATOR RH (SENS VOLTAGE)




(a) Measure the voltage between the terminals of the connector when the outside door handle is touched.
Standard voltage:






OK -- CHECK OPERATION OF DOOR ELECTRICAL KEY OSCILLATOR RH
NG -- Continue to next step.

4. CHECK WIRE HARNESS (DOOR ELECTRICAL KEY OSCILLATOR RH - CERTIFICATION ECU)




(a) Disconnect the D17 oscillator connector.
(b) Disconnect the S11 ECU connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

5. CHECK OPERATION OF DOOR ELECTRICAL KEY OSCILLATOR RH
(a) After replacing the door electrical key oscillator on the front passenger's side with a new one, check that the entry unlock function operates normally.
OK:
Entry unlock function operates normally.
OK -- REPLACE DOOR ELECTRICAL KEY OSCILLATOR RH
NG -- Continue to next step.

6. CHECK WIRE HARNESS (DOOR ELECTRICAL KEY OSCILLATOR RH - ELECTRICAL
KEY ANTENNA)




(a) Disconnect the D17 oscillator connector.
(b) Disconnect the E9 antenna connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE ELECTRICAL KEY ANTENNA RH
7. CHECK WIRE HARNESS (DOOR ELECTRICAL KEY OSCILLATOR RH - CERTIFICATION ECU)




(a) Disconnect the D17 oscillator connector.
(b) Disconnect the S11 ECU connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE CERTIFICATION ECU
