October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Test 1 - Power Supply Check
- Unplug ECU connectors at ECU. Turn ignition on, and check for battery voltage at ECU connector terminal No. 4 and 41. If battery voltage is present, go to step 2). If no voltage at terminals, check main relay, ignition switch, fuses, fusible links, and circuits.
- Check for continuity between ECU connector terminal No. 38, No. 39, and ground. If ohmmeter does not show continuity to ground, check ground connection, terminal ends, and wires.
