CONSULT-II Functions

CAUTION:
^ Do not use the "function test" for diagnosis. For more information, refer to the separate volume "CONSULT-II OPERATION MANUAL (Function Test)".
^ When CONSULT-II is connected and communicating, 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 seconds.
^ When the self-diagnosis, data monitor, or active test functions are being executed, EBD, ABS, TCS, and VDC control is not performed.
^ When using CONSULT-II to perform ABS actuator and electric unit (control unit) self-diagnosis, active test, work support, etc., first stop engine, connect CONSULT-II, and select "ABS".
^ When an error is shown by the CONSULT-II SELF-DIAG RESULTS and CONSULT-II is used to perform an active test, an engine system malfunction may be shown, but restarting engine will return the status to normal.
^ When data monitoring is executed by using CONSULT-II, a malfunction code may be indicated as the result of the real time diagnosis. In such a case, execute data monitoring in manual mode. Refer to CONSULT-II Operation Manual.





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 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 "SELECT SYSTEM" screen. If "ABS" is not indicated, go to "CONSULT-II Data Link Connector (DLC) Circuit".





6. Select the required diagnostic location from the "SELECT DIAG MODE" screen.
For further information, see CONSULT-II Operation Manual.

SELF-DIAGNOSIS
Description
^ If an error is detected in the system, ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp on the combination meter turn on. In this case, perform self-diagnosis as follows:
^ While CONSULT-II is used, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp may be turned on in a case of no malfunctioning.

Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to 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 vehicle, with the engine running, touch "START (NISSAN BASED VHCL)", "ABS", "SELFDIAG RESULTS" in order on the CONSULT-II screen.

CAUTION: If "START (NISSAN BASED VHCL)" is touched immediately after starting 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. If it cannot be shown after several attempts, ABS actuator and electric unit (control unit) may have malfunctioned.

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 ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp.

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

CAUTION:
^ In a case that a wheel sensor is malfunctioning, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp will turn on. If vehicle is not driven at approximately 30 km/h (19 MPH) for at least approximately 1 minute after repair of the wheel sensor system, ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may not turn off even if everything is normal. Check again to make sure that there is no malfunction on other parts.

9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start 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-perform 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 ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp are OFF.
