TERMINALS OF ECU

CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

(a) Disconnect the A10, K10 and G40 certification ECU (smart key ECU assembly) connectors.

(b) Measure the voltage and resistance according to the value(s) in the table below.

HINT:

Measure the values on the wire harness side with the connector disconnected.

A10-16 (NE) - Body ground	B - Body ground	Input	Engine speed signal	Always	10 kΩ or higher	Engine Condition
K10-25 (STP1) - Body ground	BE - Body ground	Input	Stop light switch signal	Brake pedal depressed → Brake pedal released	9 V or higher → 1 V or less	Stop Light Switch1

G40-21 (SSW2) - Body ground	L - Body ground	Input	SSW2 contact signal HINT: Backup for SSW1. Behaves the same way as SSW1.	Engine switch pushed → Engine switch not pushed	Below 15 Ω → 10 kΩ or higher	Start Switch2
G40-23 (SSW1) - Body ground	GR - Body ground	Input	SSW1 contact signal	Engine switch pushed → Engine switch not pushed	Below 15 Ω → 10 kΩ or higher	Start Switch1

*: In order to prevent the vehicle battery from being depleted when the vehicle is shipped long distances, a fuse that cuts unnecessary electrical load while the vehicle is being shipped is installed in the circuit. If the fuse is removed, the circuit becomes open. If the fuse that is between the vehicle battery and terminal CUTB is removed and the circuit is open, the certification ECU (smart key ECU assembly) changes to a certain control mode (example: the transmission of radio waves every 0.25 seconds, which form the detection area, stops).

(d) Measure the voltage and resistance, and check for pulses according to the value(s) in the table below.
