DIAGNOSTICS - ABS WITH EBD & BA & TRAC & VSC SYSTEM
DI6BD-04
DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
When removing the part, turn the ignition switch OFF.
HINT:
S Using SST 09843-18020, connect terminals Tc and E1 of DLC1.
S If any abnormality is not found when parts are inspected, inspect the ECU.
S If a malfunction code is displayed during the DTC check, check the circuit listed that code. For details
of each code, turn to the page in the "See page" for respective "DTC No." in the DTC chart.
S EBD shall be checked according to the ABS trouble code chart.
