DETECTION CONDITION
•  Coil antenna power supply circuit voltage is lower than the specification when the circuit is active.
POSSIBLE CAUSE
•  Coil antenna connector or terminals malfunction
•  Keyless control module connector or terminals malfunction
•  Short to ground in wiring harness between the following terminals:
―  Coil antenna terminal D—Keyless control module terminal 3M
•  Coil antenna malfunction
•  Keyless control module malfunction

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 terminal (wiring harness-side) and body ground:
―  Coil antenna terminal D
•  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 the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the keyless control module and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Replace the coil antenna, then go to the next step.
(See COIL ANTENNA REMOVAL/INSTALLATION.)
No
Go to Step 6.
5
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the keyless control module and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION.)
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.
