DTC Confirmation Procedure

NOTE:
- If both DTC P0120 (040(3) and DTC P0510 (020(3) are displayed, first perform "DTC P0510 CLOSED THROTTLE POSITION SWITCH".
- Perform "PROCEDURE FOR MALFUNCTION A" first. If the 1st trip DTC cannot be confirmed, perform "PROCEDURE FOR MALFUNCTION B". If there is no problem on "PROCEDURE FOR MALFUNCTION B", perform "PROCEDURE FOR MALFUNCTION C".
- If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.





PROCEDURE FOR MALFUNCTION A

CAUTION: Always drive vehicle at a safe speed.

TESTING CONDITION:
- Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
- This test 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
(1) Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT.
(2) Start engine and maintain the following conditions for at least 5 consecutive seconds.
Vehicle speed: More than 4 km/h (2 MPH)
Selector lever:
Suitable position except "P" or "N" position

With GST
(1) Start engine and maintain the following conditions for at least 5 consecutive seconds.
Vehicle speed: More than 4 km/h (2 MPH)
Selector lever:
Suitable position except "P" or "N" position
(2) Select "MODE 7" with GST.

No Tools
(1) Start engine and maintain the following conditions for at least 5 consecutive seconds.
Vehicle speed: More than 4 km/h (2 MPH)
Selector lever:
Suitable position except "P" or "N" position
(2) Turn ignition switch "OFF" and wait at least 5 seconds.
(3) Turn ignition switch "ON" and perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.





PROCEDURE FOR MALFUNCTION B

With CONSULT
(1) Turn ignition switch "ON".
(2) Select "DATA MONITOR" mode with CONSULT.
(3) Start engine and let it idle for at least 10 seconds.

With GST
(1) Start engine and let it idle for at least 10 seconds.
(2) Select "MODE 7" with GST.

No Tools
(1) Start engine and let it idle for at least 10 seconds.
(2) Turn ignition switch "OFF" and wait at least 5 seconds.
(3) Turn ignition switch "ON" and perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.

















PROCEDURE FOR MALFUNCTION C

CAUTION: Always drive vehicle at a safe speed.

With CONSULT
(1) Start engine and warm it up to normal operating temperature.
(2) Turn ignition switch "OFF" and wait at least 5 seconds.
(3) Turn ignition switch "ON".
(4) Select "MANU TRIG" and "HI SPEED" in "DATA MONITOR" mode with CONSULT.
(5) Select "THRTL POS SEN" and "ABSOL TH.P/S in "DATA MONITOR" mode with CONSULT.
(6) Press RECORD on CONSULT SCREEN at the same time accelerator pedal is depressed.
(7) Print out the recorded graph and check the following:
- The voltage rise is linear in response to accelerator pedal depression.
- The voltage when accelerator pedal is fully depressed is approximately 4 V.
If NG, go to "Diagnostic Procedure". If OK, go to following step.
(8)Select "AUTO TRIG" in "DATA MONITOR" mode with CONSULT.
(9) Maintain the following conditions for at least 10 consecutive seconds.
CMPS.RPM (REF): More than 2,000 rpm
MAS AIR/FL SE: More than 3 V
COOLAN TEMP/S: More than 70°C (158°F)
IACV-AAC/V: Less than 80%
Selector lever: Suitable position
Driving location:
Driving vehicle uphill (Increased engine load) will help maintain the driving conditions required for this test.

With GST
(1) Start engine and warm it up to normal operating temperature.
(2) Maintain the following conditions for at least 10 consecutive seconds.
Gear position: Suitable position
Engine speed: More than 2,000 rpm
Voltage between ECM terminal 54 (Mass air flow sensor signal) and ground:
More than 3 V
Voltage between ECM terminal 101 (IACV-AAC valve signal) and ground:
More than 4 V
(3) Select "MODE 7" with GST.

No Tools
(1) Start engine and warm it up to normal operating temperature.
(2) Maintain the following conditions for at least 10 consecutive seconds.
Gear position: Suitable position
Engine speed: More than 2,000 rpm
Voltage between ECM terminal 54 (Mass air flow sensor signal) and ground:
More than 3 V
Voltage between ECM terminal 101 (IACV-AAC valve signal) and ground:
More than 4 V
(3) Stop the vehicle, turn ignition switch "OFF", wait at least 5 seconds and then turn "ON".
(4) Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
