DTC Confirmation Procedure
1)Set ignition “ON”.
2)Close all doors.
3)Open a door for more than 4 seconds.
DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Antenna circuit check
1)Check that ignition is “OFF”.
2)Disconnect related antenna and “L21” connectors.
3)Check for proper terminal connection to antenna and “L21” connectors.
4)If connections are OK, check the following points.
•Resistance of “A1” and “A2”, “B1” and “B2”, “C1” and “C2”, “D1” and “D2” or “E1” and “E2” circuits: less than 1 Ω
•Resistance between each of “A1” and “A2”, “B1” and “B2”, “C1” and “C2”, “D1” and “D2” or “E1” and “E2” circuits and ground: infinity •Resistance between “A1” and “A2” circuit terminals at mid inside antenna connector: infinity •Resistance between “B1” and “B2” circuit terminals at rear inside antenna connector: infinity •Resistance between “C1” and “C2” circuit terminals at driver side outside antenna connector: infinity •Resistance between “D1” and “D2” circuit terminals at passenger side outside antenna connector: infinity •Resistance between “E1” and “E2” circuit terminals at rear outside antenna connector: infinity •Voltage of “A1” and “A2”, “B1” and “B2”, “C1” and “C2”, “D1” and “D2” or “E1” and “E2” circuits: approx. 0 V (when ignition is “ON”) Is check result OK?
|
Go to Step 2.
|
Repair or replace defective wire harness.

Antenna check
1)Check antenna related to DTC.
Is check result OK?
|
Replace keyless start control module and recheck DTC.
|
Replace defective antenna.
