The 186 portable PDF clearly maps and E5-16 (CAN L) . Many aftermarket scanners fail because a previous mechanic tapped the wrong pins. Use the PDF to back-probe the ECU connector – correct CAN voltage is 60 ohms resistance between H and L with key off. Tachometer output signal for your dashboard RPM gauge
To systematically diagnose or wire a 2NZ-FE engine control system, technicians must measure physical voltages under varying ignition states. Below is an operational voltage mapping chart constructed from official factory wire documentation: Pin Designation Circuit System / Wire Identity Testing Environment Expected Reference Target System Ground Reference All Conditions Exactly 0 Volts A2 Idle Air Control (IAC) Valve Ignition ON / Connector C Open 0 to 3 Volts A3 Ignition Coil Feedback (IGF) Engine Idling Oscillating Pulse (4.5–5.5V static) A5 Transmission Neutral/Drive Switch Selector Placed in "D" Full Battery Voltage A6 Brake Lamp Switch Circuit Brake Pedal Depressed Full Battery Voltage ( B1 to B4 Electronic Fuel Injector Control Engine Crank / Warm Idle Grounding Square Wave Pulse B12 Data Link Connector (DLC3) Comms OBD2 Scanning Cycle Active 5V Serial Data Pulse C6 Ignition Switched Live (IG3) Key Position set to ON Full Battery Voltage C12 Heated Oxygen Sensor (OX1) Closed Loop Engine Operation Rapid Cycle between 0.1V to 0.9V Core Wire Systems and Actuator Operation 1.
