CONSULT-II FunctionsCONSULT-II FUNCTION APPLICATION TABLE
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 sec.
^ When the self-diagnosis, data monitor, or active test functions are being executed, ABS, TCS, and VDC control is not performed.
^ When using CONSULT-II to perform VDC/TCS/ABS 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.
SELF-DIAGNOSIS
Description
If a malfunction is detected in system, ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp on meter turn on. In this case, perform self-diagnostic as follows:
Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector (data link connector is on lower instrument cover).
3. Start engine and drive vehicle at approximately 30 km/h (19 MPH) for approximately 1 minute.
4. After stopping vehicle, with engine still idling, touch "START", "ABS", and "SELF-DIAG RESULTS" on CONSULT-II screen in this order.
CAUTION: Just after starting engine, or turning ignition switch ON, "ABS" may not be displayed on system selection screen even if "START" is touched. In this case, start self-diagnostic again from step 1. If it cannot be shown after several attempts, VDC/TCS/ABS control unit may have malfunctioned. Repair or replace control unit.
5. Self-diagnostic results is displayed. (If necessary, touch "PRINT" to print self-diagnostic results.)
^ When "NO FAILURE" is shown, check ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp. Refer to "For Fast and Accurate Diagnosis". Precautions For Diagnosis
^ CONSULT-II self-diagnostic results are displayed without regard to occurrence timing. In some cases later ones (timing value is small) appear on next screen.
6. Go to appropriate "Inspection" chart according to "Display Item List", and repair or replace as necessary.
7. Start engine and drive vehicle at approximately 30 km/h (19 MPH) for approximately 1 minute.
CAUTION: Check again to make sure that there is no malfunction on other parts.
8. Turn ignition switch OFF to prepare for erasing memory.
9. Start engine and touch "START", "ABS", "SELF-DIAG RESULTS", and "ERASE MEMORY" on CONSULT-II screen in this order to erase memory.
CAUTION: If memory cannot be erased, go to step 6.
10. Drive vehicle at approximately 30 km/h (19 MPH) and make sure ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp stay off.
CAUTION: VDC "OFF" switch should not stay in the "ON" position.
Display Item List
Note 1. If wheel sensor 2 for each wheel is indicated, check 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 diagnostic for CAN communication line first.
