First, locate your ECU part number. It's under the passenger kick panel or behind the glove box. Common in the L910S series

Often associated with specialized sensor signals like the speed sensor. Troubleshooting and Resources Often associated with specialized sensor signals like the

: Ensure the ECU casing and the E1/E01 pins have solid continuity to the chassis, as poor grounding is a common cause of erratic idling.

This is a tricky request because refers to the Daihatsu Mira / Cuore L700 series (late 1990s–early 2000s), and ECU pinouts vary significantly by:

| Symptom | Likely Cause | Pin to Check | | :--- | :--- | :--- | | Cranks, no start | No power to EFI relay | A4 (should read 12V with key ON) | | Rich idle, black smoke | Oxygen sensor heater ground fault | B10 signal stuck at 0V or 1V constant | | Intermittent stalling | Loose crankshaft position sensor plug | B2 (wiggle test while monitoring signal) | | Cooling fans run constantly | Shorted fan relay control wire | C6 or C7 shorted to ground | | No boost (turbo models) | Wastegate solenoid wiring broken | C9 (check for 10-15 ohms across solenoid) |
