Pinout Values and Diagnostic Parameters

2GR-FE STARTING: SMART KEY SYSTEM: TERMINALS OF ECU

1. CHECK POWER SOURCE CONTROL ECU ASSEMBLY





(a) Disconnect the D44 ECU connector.

(b) Measure the resistance and voltage of the wire harness side connector.

Standard:





If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the D44 ECU connector.

(d) Measure the voltage of the connector.

Standard voltage:





*1: Voltage is output only when the engine is cranking.

*2: Voltage is output for 0.3 seconds after engine start.

If the result is not as specified, the ECU may have a malfunction.
