DTC P245D:00 [MZR-CD 2.2]

id0102f3877800

DTC P245D:00

EGR cooler bypass valve control solenoid control circuit high input
DETECTION CONDITION
•  The PCM monitors the EGR cooler bypass valve control solenoid valve control signal voltage. If the EGR cooler bypass valve control solenoid valve control signal voltage is more than 3.0 V for 5 s while it is turned to on, the PCM determines that the EGR cooler bypass valve control solenoid valve control circuit has malfunction.
Monitoring condition
•  Battery voltage:8—20 V
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (mode2) and snapshot data are available.
•  DTCs are stored in the PCM memory.
POSSIBLE CAUSE
•  EGR cooler bypass valve control solenoid valve connector or terminal malfunction
•  EGR cooler bypass valve control solenoid valve malfunction
•  PCM connector or terminal malfunction
•  Short to power supply in wiring harness between EGR cooler bypass valve control solenoid valve terminal B and PCM terminal 1CJ
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED
•  Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (mode2) and snapshot data on the repair order, then 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
INSPECT POOR CONNECTION OF EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE CONNECTOR
•  Switch the ignition to off.
•  Disconnect the EGR cooler bypass valve control solenoid valve connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal and/or connector, then go to Step 7.
No
Go to the next step.
4
INSPECT EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE
•  Inspect the EGR cooler bypass valve control solenoid valve.
•  Is the EGR cooler bypass valve control solenoid valve normal?
Yes
Go to the next step.
No
Replace the EGR cooler bypass valve control solenoid valve, then go to Step 7.
(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD 2.2].)
5
INSPECT POOR CONNECTION OF PCM CONNECTOR
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal and/or connector, then go to Step 7.
No
Go to the next step.
6
INSPECT EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE CONTROL CIRCUIT SHORT TO POWER SUPPLY
•  EGR cooler bypass valve control solenoid valve and PCM connectors are disconnected.
•  Switch the ignition to ON (Engine off).
•  Measure the voltage between EGR cooler bypass valve control solenoid valve terminal B (wiring harness-side) and body ground.
•  Is the voltage above 3.0 V?
Yes
Repair or replace the wiring harness for short to power supply, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING OF DTC P245D:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Switch the ignition to ON.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this 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.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD 2.2].)
No
DTC troubleshooting completed.
