Initial Inspection and Diagnostic Overview

IGNITION E.C.U EZ 115 K





The EZ 115 K ignition E.C.U. (H75) incorporates an "AUTODIAGNOSTIC" feature which enables it to identify some of the eventual faults which may occur in the system during operation.

This is done through the indicator in the lower left corner of the instrument cluster (orange LED) (L32)

The number of flashes of this indicator will determine which component within the system is at fault.

Operation of the LED

Normal operation
- Ignition key "ON" --> LED ON
- Engine started --> LED OFF

If the LED remains ON or OFF : check its power supply and its ground

- An occasional blink of the LED --> Normal Operation
- A constant flashing of the LED --> Malfunction in the ignition system

If the LED emits continous flashes, it indicates a maximum retard, or a possible overheat, poor gasoline, incorrect cartographic mapping.
