|
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 SUCTION CONTROL VALVE CONNECTOR CONDITION
• Switch the ignition off.
• Disconnect the suction control valve 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 10.
|
No
|
Go to the next step.
|
||
4
|
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO GROUND
• Verify that the suction control valve connector is disconnected.
• Inspect for continuity between the following terminals (wiring harness-side) and body ground:
• Is there continuity?
|
Yes
|
Disconnect the PCM connector and inspect the wiring harness for short to ground.
• If the short to ground circuit could be detected in the wiring harness:
• If the short to ground circuit could not be detected in the wiring harness:
Go to Step 10.
|
No
|
Go to the next step.
|
||
5
|
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 10.
|
No
|
Go to the next step.
|
||
6
|
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO POWER SUPPLY
• Verify that the suction control valve and PCM connectors are disconnected.
• Switch the ignition ON (engine off).
• Measure the voltage at the following terminals (wiring harness-side):
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• Suction control valve terminal A—PCM terminal 1CC
• Suction control valve terminal B—PCM terminal 1BY
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 power supply.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to power supply.
Go to Step 10.
|
||
7
|
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO EACH OTHER
• Verify that the suction control valve and PCM connectors are disconnected.
• Switch the ignition off.
• Inspect for continuity between suction control valve terminals A and B (wiring harness-side).
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• Suction control valve terminal A—PCM terminal 1CC
• Suction control valve terminal B—PCM terminal 1BY
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 each other.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to each other.
Go to Step 10.
|
No
|
Go to the next step.
|

8
|
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR OPEN CIRCUIT
• Verify that the suction control valve and PCM connectors are disconnected.
• Inspect for continuity between the following terminals (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 the following terminals:
• Suction control valve terminal A—PCM terminal 1CC
• Suction control valve terminal B—PCM terminal 1BY
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 Step 10.
|
||
9
|
INSPECT SUCTION CONTROL VALVE
• Inspect the suction control valve.
• Is there any malfunction?
|
Yes
|
Replace the suction control valve, then go to the next step.
|
No
|
Go to the next step.
|
||
10
|
VERIFY DTC TROUBLESHOOTING COMPLETED
• Always reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
