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 there any malfunction?
Yes
Repair or replace the connector or terminals, then go to the next step.
No
Go to the next step.
2
INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION
•  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 the next step.
No
Go to the next step.
3
INSPECT PUSH BUTTON START CONNECTOR CONDITION
•  Disconnect the push button start 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 the next step.
No
Go to the next step.
4
INSPECT COIL ANTENNA POWER SUPPLY CIRCUIT FOR SHORT TO POWER SUPPLY
•  Reconnect the negative battery cable.
•  Measure the voltage between keyless control module terminal 4Q (wiring harness-side) and body ground.
•  Is the voltage more than 2.2 V?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to the next step.
No
Go to the next step.
5
INSPECT PUSH BUTTON START
•  Reconnect the push button start connector.
•  Measure the voltage between keyless control module terminal 4Q (wiring harness-side) and body ground.
•  Is the voltage more than 2.2 V?
Yes
Replace the push button start, then go to the next step.
(See PUSH BUTTON START REMOVAL/INSTALLATION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
Go to the next step.
6
INSPECT COIL ANTENNA
•  Reconnect the coil antenna connector.
•  Measure the voltage between keyless control module terminal 4Q (wiring harness-side) and body ground.
•  Is the voltage more than 2.2 V?
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 the next step.
7
PERFORM DTC INSPECTION
•  Reconnect the keyless control module connector.
•  Clear the DTC from the keyless control module and PCM memory using the M-MDS.
•  Disconnect the negative battery cable.
•  Reconnect the negative battery cable.
Note
•  The keyless control module performs on-board self-diagnostics while the negative battery cable is connected.
•  Perform the immobilizer system (advanced keyless entry and push button start system) DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Replace the keyless control module and program the immobilizer system-related parts, then go to the next step.
(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].)
No
Go to the next step.
8
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.
