CONSULT-III Function (ABS)INFOID:0000000005147962
FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
SELF DIAGNOSTIC RESULT MODE
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-diagnosis Results
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,
VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the
system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approxi-
mately 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 “ON” position.

For details, refer to CCS-56, "Diagnostic Trouble Code (DTC) Chart".
NOTE:
“DTC RESULTS” and “TIME” are indicated on “Self Diagnostic Result”. “TIME” is used as a reference data of
diagnosis. It shows when malfunction is detected.
“TIME” shows the following.
• 0: malfunction is detected at present (from malfunction detection to ignition switch OFF).
CAN communication ([U1000], [U1010])
• 1 ~ 39: Displays when it is normal at present and finds malfunction in the past. It increases like
0→ 1→ 2...38→ 39 after returning to the normal condition whenever IGN OFF→ ON. If it is over 39, it is fixed to
39 until the self-diagnostic results are erased. It retu rns to 0 when malfunction is detected again in the pro-
cess.
Other than CAN communication (other than [U1000], [U1010])
• 1 ~ 49: Displays when it is normal at present and finds malfunction in the past. It increases like 0→ 1→ 2...48→ 49 after returning to the normal condition whenever IGN OFF→ ON. If it is over 49, it is fixed to

ERASE SELF-DIAGNOSIS
• In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
• However, this information is erased by turning igni tion switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-III.

Operation Procedure
1. Connect CONSULT-III.
2. Touch DATA MONITOR.
3. Select from SELECT MONITOR ITEM, screen of data monitor mode is displayed.

Refer to EC-72, "Generic Scan Tool (GST) Function".
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-55, "Malfunction Indicator Lamp (MIL)".
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
When the ignition switch is switched “ON”, the A/T CHECK indicator lamp lights up for 2 seconds. As a method
for locating the suspect circuit, when the self-diagnosti cs start signal is input, the memory for the malfunction
location is output and the A/T CHECK indicator lamp flashes to display the corresponding DTC.
Diagnostic Procedure
1.CHECK A/T CHECK INDICATOR LAMP
1. Start the engine with selector lever in “P” pos ition. Warm engine to normal operating temperature.
2. Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.
3. Wait 10 seconds.
4. Turn ignition switch ON. (Do not start engine.)
