After repair procedure, go to Step 9.
2
INSPECT COMBINED SENSOR
•  Inspect the combined sensor.
•  Is the combined sensor normal?
Yes
Go to the next step.
No
Replace the combined sensor.
(See COMBINED SENSOR REMOVAL/INSTALLATION.)After replacement, go to Step 9.
3
INSPECT DSC HU/CM CONNECTOR CONDITION
•  Disconnect the DSC HU/CM 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 9.
4
INSPECT BCM CONNECTOR CONDITION
•  Disconnect the BCM 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 9.
5
INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION
•  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 9.
6
INSPECT ABS DRIVER CIRCUIT FOR SHORT CIRCUIT TO GROUND
•  Inspect for continuity between the following terminals and body ground.
―  Combined sensor connector terminal D
―  DSC HU/CM connector terminal AF
•  Is there continuity?
Yes
Repair/replace the malfunctioning vehicle wiring harness.After repair procedure, go to Step 9.
No
Go to the next step.
7
INSPECT DSC HU/CM
•  Reconnect the DSC HU/CM connector.
•  Reconnect the negative battery cable.
•  Switch the ignition to ON.
•  Measure the voltage at DSC HU/CM connector terminal AF.
•  Is the voltage normal?
Yes
Go to the next step.
No
Replace the DSC HU/CM.
(See DSC HU/CM REMOVAL/INSTALLATION.)
After replacement, go to Step 9.
8
INSPECT BCM
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Reconnect the BCM connector.
•  Reconnect the negative battery cable.
•  Switch the ignition to ON.
•  Measure the voltage at BCM connector terminal 1E and 6K.
•  Is the voltage normal?
Yes
Go to the next step.
No
Replace the BCM.
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
After replacement, go to the next step.
9
VERIFY DTC
•  Reconnect the disconnected connectors and the negative battery cable.
•  Clear DTC using the M-MDS.
•  Verify DTC 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.
(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.
10
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are there other DTCs output?
Yes
Perform the corresponding DTC inspection.
No
DTC troubleshooting completed.
