NOTE
• Before performed troubleshooting, be sure to read the “Precautions of ECM Circuit Inspection: in
related manual”.
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits: ”.
• When A/C evaporator outlet air temp. is below 0 °C (32 °F) (for J20 engine) or 1.3 °C (34.3 °F) (for M16
engine), A/C remains OFF (“E23-49” terminal voltage becomes 10 – 14 V). This condition is not
abnormal.
