•  TCM connector or terminals malfunction
•  TCM power supply circuit malfunction
?  Short to ground in wiring harness between AT 15 A fuse and TCM terminal A
?  AT 15 A fuse malfunction
?  Open circuit in wiring harness between battery positive terminal and TCM terminal A
?  Open circuit in wiring harness between TCM terminal B and body ground

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture of the PC function.
•  Record the freeze frame data/snap shot data.
—
Go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY PCM DTC
•  Perform the PCM DTC inspection using the M-MDS.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-G 2.5T)].)
No
Go to the next step.
4
INSPECT BATTERY
•  Inspect the battery terminals for looseness.
•  Inspect the battery.
•  Is there any malfunction?
Yes
Connect the battery terminals securely, and recharge or replace the battery, then go to Step 8.
(See BATTERY RECHARGING.)
(See BATTERY REMOVAL/INSTALLATION.)
No
Go to the next step.
5
INSPECT GENERATOR
•  Inspect the generator.
•  Is there any malfunction?
Yes
Replace the generator, then go to Step 8.
(See GENERATOR REMOVAL/INSTALLATION [WITHOUT i-ELOOP (SKYACTIV-G 2.5T)].)
(See GENERATOR REMOVAL/INSTALLATION [WITH i-ELOOP (SKYACTIV-G 2.5T)].)
No
Go to the next step.
6
INSPECT TCM CONNECTOR AND TERMINALS
•  Switch the ignition off.
•  Disconnect the TCM connector.
•  Visually inspect the TCM connector and terminals.
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
7
INSPECT TCM POWER SUPPLY CIRCUIT
•  Always reconnect all disconnected connectors.
•  Access the PID VPWR using the M-MDS.
•  Is the PID value B+?
Yes
Go to the next step.
No
Inspect the AT 15 A fuse.
•  If the fuse is blown:
?  Refer to the wiring diagram and verify whether or not there is a common connector between AT 15 A fuse and TCM terminal A.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to ground.
•  Replace the fuse.
•  If the fuse is deteriorated:
?  Replace the malfunctioning fuse.
•  If the fuse is normal:
?  Refer to the wiring diagram and verify whether or not there is a common connector between battery positive terminal and TCM terminal A.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to the next step.
8
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC using the M-MDS.
•  Perform the following procedure to ensure that the DTC has been resolved:
1.  Drive the vehicle for 5 s or more under the following condition:
•  Selector lever position: D or R position
•  Perform the DTC inspection using the M-MDS.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (GW6A-EL, GW6AX-EL)].)
No
