CONSULT-II Functions

CAUTION:
- Do not use the "function test" for diagnosis.
- When the CONSULT-II is connected and communicating, the ABS warning lamp, SLIP indicator lamp, and VDC OFF indicator lamp turn on, and when the communication is interrupted, the lamps will turn off after approximately 2 to 3 second.
- When the self-diagnosis, data monitor, or active test functions are being executed, EBD, ABS, TCS, and VDC control is not conducted.
- When using CONSULT-II to conduct VDC/TCS/ABS control unit self-diagnosis, active test, work support, etc., first stop engine, connect the CONSULT-II, and select "ABS".
- CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some cases later ones (timing value is small) appear on the next screen.
- When an error is shown by the CONSULT-II SELF - DIAG RESULTS and CONSULT-II is used to conduct an active test, an engine system malfunction may be shown, but restarting the engine will return the status to normal.





CONSULT-II FUNCTION APPLICATION TABLE (MAIN ITEMS)

CONSULT-II BASIC OPERATION PROCEDURE
1. Turn ignition switch OFF.





2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

CAUTION: If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.

3. Turn ignition switch ON.





4. Touch "START (NISSAN BASED VHCL)".





5. Touch "ABS" in the "Diagnosis System Selection" screen.
If "ABS" is not indicated, go to "CONSULT-II Data Link Connector (DLC) Circuit".





6. Select the required diagnostic location from the "Diagnosis Mode Selection" screen. For further information, see the CONSULT-II Operation Manual.

SELF-DIAGNOSIS
Description
If an error is detected in the system, ABS warning lamp on the combination meter turn on. In this case, perform self-diagnosis as follows:

Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

CAUTION: If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.

3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.
5. After stopping the vehicle, with the engine running, touch "START (NISSAN BASED VHCL)", "ABS", "SELF-DIAG RESULTS" in order on the CONSULT-II screen.

CAUTION: If "START (NISSAN BASED VHCL)" is touched immediately after starting the engine or turning on the ignition switch, "ABS" might not be displayed in the System Selection screen. In this case, repeat the operation from step 1.

6. The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by touching "PRINT".)
- When "NO FAILURE" is displayed, check the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp.

7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning component.
8. Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.

CAUTION:
- When a wheel sensor "short-circuit" is detected, if the vehicle is not driven at 30 km/h (19 MPH) for at least 1 minute, the ABS warning lamp will not turn off even if everything is normal.

9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch "START (NISSAN BASED VHCL)", "ABS", "SELF-DIAG RESULTS", "ERASE MEMORY" in order on the CONSULT-II screen to erase the error memory.
If "ABS" is not indicated, go to "CONSULT-II Data Link Connector (DLC) Circuit".

CAUTION: If the error memory is not erased, re-conduct the operation from step 5.

11. For the final inspection, drive at approximately 30 km/h (19 MPH) for approximately 1 minute and confirm that the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp are off.

Note 1: After completing repairs of the shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Check that ABS warning lamp turns off while driving the vehicle at approximately 30 km/h (19 MPH) for approximately 1 minute according to self-diagnosis procedure. In addition, if wheel sensor 2 is displayed for the wheels, check the wheel sensor circuit and also check the control unit power voltage.
Note 2: When errors are detected in several systems, including the CAN communication system [U1000], troubleshoot the CAN communication system.
