Check Engine Light (CALIFORNIA)

Malfunction indicator light will illuminate when key is turned to ON position. It remains on for several seconds after engine has started. Self-diagnostic system monitors all input signals from each sensor. If an abnormal input signal occurs, the malfunction indicator light will illuminate and a code will be stored in ECU memory. For additional information, see TESTS W/CODES article.

NOTE: ECU diagnostic memory is kept alive by direct power supply from the battery. Memory is not erased by turning ignition off. Memory will erase if battery or ECU is disconnected.
