DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION




The control module counts the number of teeth when engine speed (RPM) exceeds 1000 rpm. The higher the engine speed (RPM), the more the number of teeth that are allowed to be missed. Diagnostic trouble code (DTC) ECM-310A is stored if control module registers a deviation in the number of teeth.

Condition

- contact resistance in terminals
- damage to carrier plate/flywheel
- defective engine speed (RPM) sensor.
