CONSULT Function (ABS)INFOID:0000000009463758
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
FUNCTION
CONSULT can display each diagnostic item us ing the following direct diagnostic modes.
ECU IDENTIFICATION
ABS actuator and electric unit (control unit) part number is displayed.
SELF DIAGNOSTIC RESULT
Operation Procedure
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
How To Erase Self Diagnostic Result
1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure t hat the ABS warning lamp, VDC OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal, unless
the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
• Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay in ON position.
Display Item List
Refer to BRC-45, "DTC Index".

DIAGNOSIS SYSTEM [
ABS ACTUATOR AND ELECTRIC UNIT (CONTROL
UNIT)]
ACTIVE TEST
The active test is used to determine and identify details of a malfunction, based on self-diagnosis test results
and data obtained in the DATA MONITOR. In response to instructions from CONSULT, instead of those from
ABS actuator and electric unit (control unit) on the vehicle, a drive signal is sent to the actuator to check its
operation.
CAUTION:
• Never perform ACTIVE TEST while driving the vehicle.
• Always bleed air from brake system before active test.
• Never perform active test when system is malfunctioning.
NOTE:
• When active test is performed while depressing the pedal, the pedal depressing stroke may change. This is not a malfunction.
• “TEST IS STOPPED” is displayed approx. 10 seconds after operation start.
• When performing active test again after “TEST IS STOPPED” is displayed, select “BACK”.
• ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON during active test. This is not a malfunction.
ABS IN Valve and ABS OUT Valve
When “Up”, “Keep” or “Down” is selected on display sc reen, the following items are displayed when system is
normal.

NO >> GO TO 7.
3.VERIFYING TYPE ID (1)
CONSULT Configuration
Compare a “Type ID” displayed on the CONSULT screen with the one searched by using FAST (service parts
catalogue) to check that these “Type ID” agree with each other.
NOTE:
For the “Type ID” searched by using FA ST (service parts catalog), use the last five digits of the “Type ID”.
>> GO TO 4.
4.SAVING TYPE ID
