Using SST (NGS Tester)

NOTE:
- PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
- ECT sensor (Water temperature sender unit).
- Camshaft position sensor.
- Main relay.

1. Connect the NGS tester to the DLC-2.
2. Turn the ignition switch to ON.
3. Select the PID/DATA MONITOR AND RECORD" function on the NGS display and press TRIGGER.
4. Select the appropriate PID on the NGS display and press START.

5. Measure the PID value.
- If PID value is not within the specification, follow the instructions in ACTION column.

NOTE:
- When measuring the following PID value, perform the following:
- FTP V PID.
- BARO V PID.
- TP V PID.
- Perform the SIMULATION TEST for the output device after PID/DATA measurement is completed.

FTP V PID inspection procedure
1. Confirm the ignition switch is turned to ON.
2. Confirm that the following PIDs are within the specifications:

BARO: 101.3 kPa {760 mmHg, 29.9 inHg} (Absolute pressure)

IAT: 30 - 100 °C {86 - 212 °F}




3. Disconnect the fuel tank pressure sensor connector and measure the voltage at fuel tank pressure sensor connector terminal C.

Voltage: 5.0 V

4. Reconnect the connector.
5. Disconnect the vacuum hose from the fuel tank pressure sensor.
6. Connect the vacuum pump to the fuel tank pressure sensor.
7. Select FTP V PID on the NGS tester and press START.
8. Apply the vacuum and verify that the FTP V is as specified on the table.

BARO V PID inspection procedure
1. Confirm the ignition switch is turned to ON.
2. Confirm that the following PIDs are within the specifications:

BARO: 101.3 kPa {760 mmHg, 29.9 inHg} (Absolute pressure)

IAT: 10 - 50 °C {50 - 122 °F}




3. Disconnect the EGR boost sensor connector and measure the voltage at EGR boost sensor connector terminal C.

Voltage: 4.5 - 5.5 V

4. Reconnect the connector.
5. Disconnect the vacuum hose from the EGR boost sensor.
6. Connect the vacuum pump to the EGR boost sensor.
7. Select BARO V PID on the NGS tester and press START.
8. Apply the vacuum and verify that the BARO V is as specified on the table.

Vref Terminal circuit inspection
1. Turn the ignition switch to ON.

2. Measure the voltage between the TP sensor connector (vehicle side) terminal A and body ground using a voltmeter.
1. Measurement voltage is 0 V.
1. Turn the ignition switch to LOCK.
2. Disconnect the TP sensor connector, EGR boost sensor connector, and fuel tank pressure sensor connector (to which Vref is applied).




3. Verify there is no continuity between the TP sensor connector (vehicle side) terminal A and body ground using an ohmmeter.
- If there is continuity, repair the related harness for short to circuit.




4. Inspect for continuity between the PCM connector (vehicle side) terminal 21 and each sensor connector (vehicle side) terminals to which Vref is applied using an ohmmeter.
- If there is continuity, repair the related harnesses.

2. Measurement voltage is B+.
1. Turn the ignition switch to LOCK.
2. Disconnect the battery positive harness and battery negative harness.




3. Verify there is no continuity between the TP sensor connector (vehicle side) terminal A and battery positive harness using an ohmmeter.
- If there is continuity, repair the related harnesses for short to B+ circuit.

3. Measurement voltage is approx. 5 V.
- Vref terminal of PCM is okay.

Ground circuit Inspection
1. Turn the ignition switch to LOCK.
2. Disconnect the PCM connectors.




3. Inspect for continuity between the PCM ground terminals and body ground using an ohmmeter.
- If not as specified, repair the related harnesses for open circuit.

Power supply circuit Inspection
1. Turn the ignition switch to LOCK.
2. Disconnect the PCM connectors.
3. Measure the voltage between the PCM battery power terminal and body ground using a voltmeter.
- If not as specified, repair the related harnesses and fuses.




Power supply terminal voltage
B+

Serial communication terminal Inspection
1. Turn the ignition switch to LOCK.
2. Disconnect PCM connectors.




3. Verify there is continuity between PCM connector terminal 1D and DLC-2 KLN terminal.
- If not as specified, repair the related harnesses.
