## HOWTO test brand new ECU design which was never fabricated before
|
|
|
|
If dealing with a brand new never before tested hardware design it's recommended to gradually add wires between vehicle connector breakout board and untested ECU.
|
|
|
|
## Prerequisites for each testing session
|
|
|
|
1. Charge battery
|
|
1. Disconnect battery charger
|
|
1. Warm up car on stock ECU
|
|
1. Charge laptop battery
|
|
1. Disconnect laptop from wall charger.
|
|
|
|
## Minimal ECU Power Test
|
|
|
|
1. Write down battery voltage measured at the battery, with charger and all ECUs physically disconnected.
|
|
1. Hook up Power GND
|
|
1. Hook up ECU power source
|
|
1. Test & Report, with USB physically disconnected: ECU status LED starts to blink if powered up, ECU status and all LED go off when powered off.
|
|
1. Test & Report, with USB physically disconnected: Attempt cranking. If equipped with on-board persistent storage, upload & link log to report.
|
|
1. Connect ECU to laptop via serial, report type of serial.
|
|
1. With laptop connected via serial, test & Report, with USB physically disconnected: ECU status LED blinks if powered up, ECU status LED blinks when ignition powered off.
