STEPCHECKYESNO

1.CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from ECM.

3) Disconnect the connectors from electronic throttle control.

4) Measure the resistance between ECM connector and chassis ground.

Connector & terminal

(B134) No. 19 — Chassis ground:

(B134) No. 18 — Chassis ground:

(B134) No. 18 — (B136) No. 4:

Is the resistance 1 M? or more?
