DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E7, F121
• Harness for open or short between EVAP canister purge volume control solenoid valve and IPDM E/R
• Harness for open or short between EVAP canister purge volume control solenoid valve and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.
CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT
FOR OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check the continuity between EVAP canister purge volume control solenoid valve harness connector and
ECM harness connector.
4.
Also check harness for short to ground and short to power.
Is the inspection result normal?
YES-1 >> With CONSULT-III: GO TO 4.
YES-2 >> Without CONSULT-III: GO TO 5.
NO
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT-III
1.
Reconnect all harness connectors disconnected.
2.

3.
Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode with CONSULT-III. Check that engine speed var-
ies according to the valve opening.
Does engine speed vary according to the valve opening?
YES
>> GO TO 6.
NO
>> GO TO 5.
5.
CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
EC-207, "Component Inspection"

Description
INFOID:0000000001056360
The vehicle speed signal is sent to the combination meter from the “ABS actuator and electric unit (control
unit)” by CAN communication line. The combination meter then sends a signal to the ECM by CAN communi-
cation line.

DTC DETECTION LOGIC
NOTE:
• If DTC P0500 is displayed with DTC U1001, first perform the trouble diagnosis for DTC U1001.Refer
.
• If DTC P0500 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
.
DTC CONFIRMATION PROCEDURE
1.
INSPECTION START
Do you have CONSULT-III?
Do you have CONSULT-III?
YES
>> GO TO 2.
NO
>> GO TO 5.
2.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
>> GO TO 3.
3.
CHECK VEHICLE SPEED SENSOR FUNCTION
NOTE:
This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
With CONSULT-III
1.
Start engine.
2.
Read “VHCL SPEED SE” in “DATA MONITOR” mode with CONSULT-III. The vehicle speed on CON-
SULT-III should exceed 10 km/h (6 mph) when rotating wheels with suitable gear position.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Go to
4.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Select “DATA MONITOR” mode with CONSULT-III.
2.
Warm engine up to normal operating temperature.
3.
Maintain the following conditions for at least 50 consecutive seconds.
CAUTION:
Always drive vehicle at a safe speed.
DTC No.
