Diagnostic Procedure

STEP

INSPECTION

ACTION
1
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.
2
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition off, then ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Is the PENDING CODE/DTC P0850:00 also present?
Yes
Go to the applicable PENDING CODE or DTC inspection.
(See DTC P0850:00 [SKYACTIV-D 2.2].)
No
Go to the next step.
3
INSPECT NEUTRAL SWITCH NO.2 CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the neutral switch No.2 connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 9.
No
Go to the next step.
4
INSPECT NEUTRAL SWITCH NO.2
•  Inspect the neutral switch No.2.
•  Is there any malfunction?
Yes
Replace the back-up light switch, then go to Step 9.
(See BACK-UP LIGHT SWITCH REMOVAL/INSTALLATION [D66M-R].)
No
Go to the next step.
5
INSPECT NEUTRAL SWITCH NO.2 GROUND CIRCUIT FOR OPEN CIRCUIT
•  Verify that the neutral switch No.2 connector is disconnected.
•  Inspect for continuity between neutral switch No.2 terminal C (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between neutral switch No.2 terminal C and body ground.
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:
•  Inspect for the following:
―  Open circuit between neutral switch No.2 and body ground
―  Loose or lifting ground point
•  Repair or replace the malfunctioning part.
Go to Step 9.
6
INSPECT NEUTRAL SWITCH NO.2 SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Verify that the neutral switch No.2 connector is disconnected.
•  Inspect for continuity between neutral switch No.2 terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
If the short to ground circuit could be detected in the wiring harness:
•  Refer to the wiring diagram and verify whether or not there is a common connector between neutral switch No.2 terminal B and PCM terminal 1EJ.
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.
If the short to ground circuit could not be detected in the wiring harness:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 9.
No
Go to the next step.
7
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 9.
No
Go to the next step.
8
INSPECT NEUTRAL SWITCH NO.2 SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  Verify that the neutral switch No.2 and PCM connectors are disconnected.
•  Inspect for continuity between neutral switch No.2 terminal B (wiring harness-side) and PCM terminal 1EJ (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between neutral switch No.2 terminal B and PCM terminal 1EJ.
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.
9
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
