Displaying & Reading Trouble Codes

Control Unit Input/Output Signal Standard








REFERENCE VALUE FROM CONSULT-II

CAUTION: The display shows the control unit calculation data, so a normal value might be displayed even in the event the output circuit (harness) is open or short circuited.

Note 1: Confirm tire pressure is normal.

Note 2: ON/OFF timing of ABS warning lamp

ON: For approximately 1.8 seconds after ignition switch is turned ON, or when a malfunction is detected.

OFF: Approximately 1.8 seconds after ignition switch is turned ON (when system is in normal operation) and TCS/VDC function is not activated.

Note 3: ON/OFF timing of VDC OFF indicator lamp

ON: For approximately 1.8 seconds after ignition switch is turned ON, or when a malfunction is detected and VDC OFF switch is ON.

OFF: Approximately 1.8 seconds after ignition switch is turned ON (when system is in normal operation.) And when VDC OFF switch is OFF.

Note 4: SLIP indicator lamp ON/OFF timing

ON: For approximately 1.8 seconds after ignition switch is turned ON, or when a malfunction is detected and TCS/VDC function is activated while driving.

OFF: Approximately 1.8 seconds after ignition switch is turned ON (when system is in normal operation) and TCS/VDC function is not activated.

Flashing: TCS/VDC function is active during driving

CONSULT-II Function (ABS)





CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.

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 carries 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 GI-36, "CONSULT-II Data Link Connector (DLC) Circuit". CONSULT-II Checking System





6. Select the required diagnostic location from the "SELECT DIAG MODE" screen.

SELF-DIAGNOSIS

Description
If an error is detected in the system, the ABS warning lamp will 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 carries 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 "COPY".)
- When "NO FAILURE" is displayed, check the ABS warning lamp, SLIP indicator lamp and VDC OFF 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 the malfunction is repaired.

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 GI-36, "CONSULT-II Data Link Connector (DLC) Circuit". CONSULT-II Checking System

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, SLIP indicator lamp, and VDC OFF indicator lamp are off.











Display Item List

Note 1. If wheel sensor 2 for each wheel is indicated, check ABS actuator and electric unit (control unit) power supply voltage in addition to wheel sensor circuit check.

Note 2. If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line first.

Note 3: "ACTUATOR RLY" on the CONSULT-II self-diagnosis results indicates the malfunction of the actuator motor relay or circuit.

DATA MONITOR

Operation Procedure
1. After turning OFF the ignition switch, 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 carries out CAN communication.

2. Touch "START (NISSAN BASED VHCL)", "ABS", "DATA MONITOR" in order on the CONSULT-II screen. If "ABS" is not indicated, go to GI-36, "CONSULT-II Data Link Connector (DLC) Circuit". CONSULT-II Checking System

CAUTION: When "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 2.

3. Return to the Monitor Item Selection screen, and touch "C/U INPUT ITEM", "MAIN ITEM" or "ITEM MENU SELECTION". Refer to the following information.
4. 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.
- The ABS and brake (EBD) warning lamps turn on during the active test.

Operation Procedure
1. Connect the CONSULT-II and CONSULT-II CONVERTER to the data link connector and start the 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 carries out CAN communication.

2. Touch "START (NISSAN BASED VHCL)" on the display screen.
3. Touch"ABS".
If "ABS" is not indicated, go to GI-36, "CONSULT-II Data Link Connector (DLC) Circuit". CONSULT-II Checking System
4. Touch "ACTIVE TEST".





5. The test item selection screen is displayed.
