The engine block relies on a heavy-duty grounding strap to the chassis. If this strap is corroded or disconnected, the ECU will attempt to use its internal grounding circuits to complete high-amperage loops. This will quickly cook the internal board.
Injector outputs (INJ / Injectors) — driver outputs (switched to ground) daihatsu hijet efse ecu pinout hot
When searching for a “hot” pinout, you need to know which pins carry high current and which carry sensitive 5V signals. The engine block relies on a heavy-duty grounding
Check for a 5V output on the terminal pin using a digital multimeter. If 5V is present, your ECU has successfully booted up and is running. 4. Troubleshooting Common EFI Electrical Failures Injector outputs (INJ / Injectors) — driver outputs
This pin is "always hot" and provides constant battery voltage to maintain the ECU's internal memory (DTC storage) even when the ignition is off.
For those performing deep electrical work, sourcing the specific for your S200 or S210 series Hijet is highly recommended, as many diagrams are rare and specific to the Japanese domestic market.
