Here is the short summary of failures for the Holden Barina MR140 ECU:
• Hot Stalling: Cuts out completely once the engine reaches normal operating temperature and will not restart until it cools down.
• Dead Cylinder Misfire: Internal driver chips burn out, permanently cutting fuel or spark to a cylinder, causing severe engine shaking.
• Erratic Idle Stalling: Fails to control the idle air system properly, causing the engine to hunt for revs or stall when you stop at lights.
• No Communication: The internal motherboard dies completely, preventing diagnostic scan tools from connecting or reading any codes.
