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-diagnostics 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.
