If the Check Engine warning light illuminates, first check the battery condition as detailed under Batteries in the General Information and Maintenance section.
If the battery is good, the EMM may have detected a fault within the electronic engine control system (and stored a diagnostic trouble code). If the EMM detects a fuel injection or electronic engine control fault, it will store a Service Code, sound the horn for 10 seconds and illuminate the gauge LED for a minimum of 30 seconds. The light will go out if the fault does not remain present, otherwise the LED will remain illuminated until the fault goes away or the key is turned off (whichever comes first). If the fault is still present the next time the engine is started, the LED will illuminate_once again to alert the operator that problem is still present.
If the Check Engine warning light illuminates, first check the battery condition as detailed under Batteries in the General Information and Maintenance section. If the battery Is good, the EMM may have detected a fault within the electronic engine control system (and stored a diagnostic trouble code). For more information, please refer to Reading Codes in the Self-Diagnostic System portion of the E-Tec Fuel Injection section.
