DTC P0245:00 [L3 Turbo]

id0102b7900000

DTC P0245:00

Wastegate control solenoid valve circuit low input
DETECTION CONDITION
•  When the PCM turns the wastegate control solenoid valve off but the wastegate control solenoid valve circuit voltage is low for 5 s, the PCM determines that the wastegate control solenoid valve control circuit voltage is low.
Diagnostic support note
•  This is a continuous monitor (other).
•  The MIL does not illuminate.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Wastegate control solenoid valve connector or terminals malfunction
•  Short to ground or open circuit in wastegate control solenoid valve power supply circuit
―  Short to ground in wiring harness between main relay and wastegate control solenoid valve terminal A
―  ENG BAR 1 15 A fuse malfunction
―  Open circuit in wiring harness between main relay and wastegate control solenoid valve terminal A
•  Short to ground in wiring harness between wastegate control solenoid valve terminal B and PCM terminal 2AA
•  Wastegate control solenoid valve malfunction
•  PCM connector or terminals malfunction
•  Open circuit in wiring harness between wastegate control solenoid valve terminal B and PCM terminal 2AA
•  PCM malfunction

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
INSPECT WASTEGATE CONTROL SOLENOID VALVE CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the wastegate control solenoid valve connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
3
INSPECT WASTEGATE CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT
•  Wastegate control solenoid valve connector is disconnected.
•  Switch the ignition to ON (engine off).
•  Measure the voltage between wastegate control solenoid valve terminal A (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Go to the next step.
No
Inspect the ENG BAR 1 15 A fuse.
•  If the fuse is melt:
―  Repair or replace the wiring harness for a possible short to ground.
―  Replace the fuse.
•  If the fuse is deterioration:
―  Replace the fuse.
•  If the fuse is normal:
―  Repair or replace the wiring harness for a possible open circuit.
Go to Step 8.
4
INSPECT WASTEGATE CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO GROUND
•  Wastegate control solenoid valve connector is disconnected.
•  Switch the ignition to off.
•  Inspect for continuity between wastegate control solenoid valve terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
If the short to ground circuit could be detected:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
•  Replace the PCM (short to ground in PCM internal circuit).
Go to Step 8.
No
Go to the next step.
5
INSPECT WASTEGATE CONTROL SOLENOID VALVE
•  Inspect the wastegate control solenoid valve.
•  Is there any malfunction?
Yes
Replace the wastegate control solenoid valve, then go to Step 8.
(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)
No
Go to the next step.
6
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
•  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 WASTEGATE CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT
•  Wastegate control solenoid valve and PCM connectors are disconnected.
•  Inspect for continuity between wastegate control solenoid valve terminal B (wiring harness-side) and PCM terminal 2AA (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOEO or KOER self test.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [L3 Turbo].)
No
DTC troubleshooting completed.
