Clearing Trouble Codes

CONSULT-II Functions
CONSULT-II MAIN FUNCTION





In a diagnosis function (main function), there are "WORK SUPPORT", "SELF-DIAGNOSTIC RESULTS", "DATA MONITOR", "CAN DIAG SUPPORT MNTR", "ACTIVE TEST", "FUNCTION TEST", "ECU PART NUMBER".

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 performs 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 GI-40. "CONSULT-II Data Link Connector (DLC) Circuit". Data Link Connector Schematic






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 perform CAN communication.

3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping 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 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 can not 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) or more 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) or more 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 GI-40. "CONSULT-II Data Link Connector (DLC) Circuit". Data Link Connector Schematic


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

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











Display Item List
Note 1: After completing repairs of shorted sensor circuit, when turning ignition switch ON, ABS warning lamp
turned on. Make that ABS warning lamp turned off while driving vehicle at approximately 30 km/h (19 MPH) or
more for approximately 1 minute according to self-diagnosis procedure. In addition, if wheel sensor 2 is displayed for wheels, check wheel sensor circuit and also check ABS actuator and electric unit (control unit) power voltage.

Note 2: If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line first.
Note 3: "ACTUATOR RELAY on the CONSULT-II self-diagnostic results indicates the malfunction of actuator relay or circuit. Actuator relay is imbedded in ABS actuator and electric unit (control unit).

DATA MONITOR
Operation Procedure
1. After turning ignition switch OFF, connect CONSULT-II and 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 performs CAN communication.

2. Turn ignition switch ON.
3. Touch "START (NISSAN BASED VHCL)", "ABS", "DATA MONITOR" in order on the CONSULT-II screen.
If "ABS" is not indicated, go to GI-40. "CONSULT-II Data Link Connector (DLC) Circuit". Data Link Connector Schematic


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

4. Return to the Monitor Item Selection screen, and touch "ECU INPUT SIGNALS", "MAIN SIGNALS" or "SELECTION FROM MENU". Refer to the following information.
5. When "START" is touched, the data monitor screen is displayed.

ACTIVE TEST

CAUTION:
^ Do not perform active test while driving.
^ Make sure to completely bleed air from the brake system.
^ Active test can not be performed when EBD, ABS, TCS or VDC operation is malfunction.
^ ABS and brake warning lamps turn on during the active test.

Operation Procedure
1. Connect CONSULT-II and CONVERTER to data link connector and start engine.

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 performs CAN communication.

2. Touch "START (NISSAN BASED VHCL) " on the display screen.
3. Touch"ABS".
If "ABS" is not indicated, go to, "CONSULT-II Data Link Connector (DLC) Circuit".





4. Touch "ACTIVE TEST."
5. The test item selection screen is displayed.
6. Touch necessary test item.
7. With the "MAIN SIGNALS" display shown in reverse, touch "START".
8. The "ACTIVE TEST" screen will be displayed, so perform the following test.
