Modes of Operation

WARNING: This page is about a different car, the 2004 Suzuki Swift + and 2004 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

There is one normal mode of operation, with the spark under the engine control module (ECM) control. If the crankshaft position (CKP) sensor pulses are lost the engine will not run. The loss of the camshaft position (CMP) signal may result in a longer crank time since the ECM cannot determine which stroke the pistons are on. Diagnostic trouble codes are available to accurately diagnose the ignition system with a scan tool.
