•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT STARTER RELAY
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Remove the starter relay.
•  Inspect the starter relay.
•  Is there any malfunction?
Yes
Replace the starter relay, then go to Step 6.
No
Install the starter relay, then go to the next step.
2
INSPECT TR SWITCH
•  Inspect the TR switch.
•  Is there any malfunction?
Yes
Replace the TR switch, then go to Step 6.
(See TRANSAXLE RANGE (TR) SWITCH REMOVAL [FS5A-EL].)
(See TRANSAXLE RANGE (TR) SWITCH INSTALLATION [FS5A-EL].)
No
Go to the next step.
3
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 Step 6.
No
Go to the next step.
4
INSPECT STARTER RELAY CIRCUIT FOR OPEN CIRCUIT
•  Keyless control module connector is disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Starter relay terminal A—Keyless control module terminal 4B
―  TR switch terminal A—Keyless control module terminal 4AA
―  TR switch terminal F—Keyless control module terminal 4K
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
5
INSPECT KEYLESS CONTROL MODULE
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Bring the valid key into the vehicle.
•  Measure the voltage at the following terminals (wiring harness-side) with the selector lever in P position:
―  Keyless control module terminal 4B
―  Keyless control module terminal 4AA
•  Is the voltage more than 4 V?
Yes
Go to the next step.
No
Replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
6
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the keyless control module using the M-MDS.
•  Switch the ignition to off.
•  Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs, replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
Go to the next step.
7
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
DTC troubleshooting completed.
