DTC Confirmation Test
WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If DTC confirmation test has been previously performed, always turn ignition off and wait at least 10 seconds before performing next DTC confirmation test.
With CONSULT-II
- Turn ignition on. Select P/N POSI SW in DATA MONITOR mode with CONSULT-II.
- Check P/N POSI SW signal under the following conditions.
- With transmission in Park or Neutral, ON should be displayed.
- With transmission not in Park or Neutral, OFF should be displayed.
If operation is as specified, go to next step. If operation is not as specified, go to appropriate DIAGNOSTIC PROCEDURE.
- Select DATA MONITOR mode with CONSULT-II. Start engine and warm to normal operating temperature.
- Maintain the following conditions for at least 60 consecutive seconds:
- ENG SPEED: 1550-3450 RPM (A/T) or 1850-4100 RPM (M/T).
- COOLAN TEMP/S: more than 158°F (70°C).
- B/FUEL SCHDL: 3.0-12.5 msec (A/T) or 2.8-10.0 msec (M/T).
- VHCL SPEED SE: more than 40 MPH.
If 1st trip DTC is detected, go to appropriate DIAGNOSTIC PROCEDURE. If 1st trip DTC is not detected, system is okay at this time.
NOTE:
Use the following test to check overall function of PNP switch circuit. During this test, DTC may not be confirmed.
CAUTION:
DO NOT use ECM ground terminals when measuring voltage.
With Generic Scan Tool (Overall Function Check)
- Turn ignition on. Measure voltage between body ground and ECM terminal No. 22 (PNP switch signal) by backprobing. See Figure and Figure .
- When transmission is in Park or Neutral, voltage should be about zero volts. When transmission is not in Park or Neutral, battery voltage should exist.
- If voltage is as specified, system is okay at this time. If voltage is not as specified, go to appropriate DIAGNOSTIC PROCEDURE.
