• After repairing the trouble, turn OFF the ignition switch and
turn ON again.
• Click the DTC inspection button 1.
• Check the DTC.
• The previous malfunction history code (Past DTC) still
remains stored in the ECM. Therefore, erase the history code
memorized in the ECM using SDS tool.

wire coupler of any sensor is disconnected. Therefore, when a
wire coupler has been disconnected at the time of diagnosis,
erase the stored malfunction history code using SDS.
• Click “Clear” 2 to delete history code (Past DTC).
• Follow the displayed instructions.
• Check that both “Current DTC” 3 and “Past DTC” 4 are
