Diagnostic Procedure

Step

Inspection

Action

1

INSPECT COIL ANTENNA CONNECTOR CONDITION

•  Switch the ignition to off.

•  Disconnect the negative battery cable.

•  Disconnect the coil antenna connector.

•  Inspect the connector and terminals (corrosion, damage, pin disconnection).

•  Is the connector normal?

Yes

Go to the next step.

No

Repair/replace the connector or terminal.

After repair procedure, go to Step 5.

2

INSPECT COIL ANTENNA POWER SUPPLY CIRCUIT FOR SHORT CIRCUIT TO GROUND

•  Reconnect the negative battery cable.

•  Switch the ignition to ON.

•  Measure the voltage at coil antenna connector terminal B.

•  Is the voltage 2.2 V or less?

Yes

Go to the next step.

No

Replace the coil antenna.

(See COIL ANTENNA REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)

After replacement, go to Step 5.

3

INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION

•  Switch the ignition to off.

•  Disconnect the negative battery cable.

•  Disconnect the keyless control module connector.

•  Inspect the connector and terminals (corrosion, damage, pin disconnection).

•  Is the connector normal?

Yes

Go to the next step.

No

Repair/replace the connector or terminal.

After repair procedure, go to Step 5.

4

INSPECT COIL ANTENNA POWER SUPPLY CIRCUIT FOR SHORT CIRCUIT TO GROUND

•  Inspect for continuity between coil antenna connector terminal B and body ground.

•  Is there continuity?

Yes

Repair/replace the wiring harness.

After repair procedure, go to the next step.

No

Go to the next step.

5

VERIFY DTC

•  Reconnect the disconnected connectors and the negative battery cable.

•  Clear DTC using the M-MDS.
(See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].)

•  Verify DTC using the M-MDS.
(See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].)

•  Is the same DTC present?

Yes

If the malfunction recurs, replace the keyless control module.

(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)

Go to the next step.

No

Go to the next step.

6

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Are there other DTCs output?

Yes

Perform the corresponding DTC inspection.

No

DTC troubleshooting completed.
