Diagnostic Procedure

STEP

INSPECTION

ACTION

1

INSPECT COIL ANTENNA CONNECTOR AND TERMINALS

•  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 there any malfunction?

Yes

Repair or replace the connector or terminals, then go to Step 5.

No

Go to the next step.

2

INSPECT KEYLESS CONTROL MODULE CONNECTOR AND TERMINALS

•  Disconnect the keyless control module connector.

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

•  Is there any malfunction?

Yes

Repair or replace the connector or terminals, then go to Step 5.

No

Go to the next step.

3

INSPECT COIL ANTENNA POWER SUPPLY CIRCUIT FOR SHORT TO GROUND

•  Coil antenna and keyless control module connectors are disconnected.

•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:

―  Coil antenna terminal A

―  Coil antenna terminal B

•  Is there continuity?

Yes

Repair or replace the wiring harness for a possible short to ground, then go to Step 5.

No

Go to the next step.

4

VERIFY COIL ANTENNA MALFUNCTION

•  Make sure to reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

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

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

•  Is the same DTC present?

Yes

Replace the coil antenna, then go to the next step.

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

No

Go to Step 6.

5

VERIFY TROUBLESHOOTING COMPLETED

•  Make sure to reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

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

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

•  Is the same DTC present?

Yes

Replace the keyless control module and program the immobilizer system-related parts.

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

(See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [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 any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].)

No

DTC troubleshooting completed.
