- CHECK DOOR ELECTRICAL KEY OSCILLATOR (OPERATION)
- Replace the door electrical key oscillator with a new one or normally functioning one. Refer to COMPONENTS [09/2012 - ] .
- Check that the entry function operates normally.
OK
Operates normally
NG → See step 9
OK → END (DOOR ELECTRICAL KEY OSCILLATOR IS DEFECTIVE)
- CHECK FRONT DOOR OUTSIDE HANDLE RH (OPERATION)
- Replace the front door outside handle RH with a new one or normally functioning one. Refer to REMOVAL [09/2012 - ] .
- Check that the entry function operates normally.
OK
Operates normally
NG → See step 19
OK → END (FRONT DOOR OUTSIDE HANDLE RH IS DEFECTIVE)
- CHECK WAVE ENVIRONMENT
- Bring the electrical key transmitter near the front passenger door outside handle, and perform a front passenger door entry lock and unlock operation check.NOTE:
If the key is brought within 0.2 m (0.6 ft.) of the door handle, communication is not possible.
HINT:
- When the electrical key transmitter is brought near the front passenger door outside handle, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
- If the inspection result is that the operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
RESULTResult Proceed to Operation check fails A Operation check is normal B
B → AFFECTED BY WAVE INTERFERENCE
A: Go to next step
- Bring the electrical key transmitter near the front passenger door outside handle, and perform a front passenger door entry lock and unlock operation check.
