How to Erase Self-diagnostic Results
1. Perform applicably inspection of malfunctioning item and then repair or replace.
2. Start engine and drive at 30 km/h (19 MPH) or more for approx. 1 minute.
3. Make sure that ABS warning lamp turns OFF.
NOTE:
Make sure that ABS warning lamp turns OFF by driving for a minute at vehicle speed of 30 km/h
(19 MPH) or more after turning ignition switch "OFF" if 4WD warning lamp turns ON with system
malfunction of “ABS SYSTEM [C1203]”. 4WD warning lamp may not turn OFF if it is normal unless
ignition switch turns OFF at once and engine restarts after that.
4. Turn ignition switch “OFF” to erase memory.
5. Start engine and select “SELF-DIAG RESULTS” mode for “ALL MODE AWD/4WD” with CONSULT-II.
6. Touch “ERASE” on CONSULT-II screen to erase DTC memory.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.
7. Drive at 30 km/h (19 MPH) or more for approx. 1 minute. Be sure 4WD warning lamp is OFF.
DATA MONITOR MODE
Operation Procedure
1. Perform “CONSULT-II SETTING PROCEDURE”. Refer to TF-29, "CONSULT-II SETTING PROCEDURE"
.
2. Touch “DATA MONITOR”.
3. Select from “SELECT MONITOR ITEM”, screen of data monitor mode is displayed.
