Ignition Test

Overview

Image Image

The Ignition Test function allows each ignition output channel to be manually fired for installation, diagnostics and troubleshooting purposes.

This function can be used to:

  • Verify ignition coil wiring.
  • Confirm cylinder numbering and firing order.
  • Check ignition output operation.
  • Verify spark plug and ignition coil functionality.
  • Diagnose ignition system faults.

The Ignition Test Dwell setting specifies the coil charge time used during the test event and is expressed in units of milliseconds (ms). A test dwell value of 3.0 to 4.0 ms is suitable for most modern inductive ignition coils.

When an ignition channel test is activated, the ECU charges the selected ignition coil for the configured test dwell period before firing a spark event. The test rate runs at 10Hz

The ignition test function operates at a fixed test rate of 10 Hz (10 ignition events per second).

⚠️ Warning

The Ignition Channel Output must have a cylinder assigned for this function to operate. See See Ignition Channel Setup for help.

Ensure the ignition system is configured correctly before performing an ignition test.

High voltages are generated during ignition testing which may cause injury or damage to ignition components if used incorrectly.

Do not perform ignition tests in the presence of fuel vapour or near flammable materials.
