The database shows that A-13 is fed by the EFI relay #2. He checks the relay—it’s fine. The database shows the wire from the relay goes to pin A-13 via a specific connector (EA1). He finds corrosion on that connector. Clean it. Now A-13 has 12V.
The database lists the crankshaft position sensor on Connector C, Pin 17 (NE+) and Pin 18 (NE-). He back-probes while cranking. Expected signal: an AC sine wave of 0.5V to 5V. He sees 0V. The sensor is dead.
❌ – Denso often places main relay power on BATT pin, but not always pin 1. ✅ Look for +B, +B1, BATT on 12V pins; E, E1, E01, E02 for grounds.
While there are commercial databases available, you can also find some publicly accessible resources:
A proper pinout database note will state: "Pin 15 (LIN) – Communicates with Immobilizer. If swapping ECU, you must re-sync using Techstream or send to a decoder."
