1.CHECK ELECTRONIC THROTTLE CONTROL RELAY.

1) Turn the ignition switch to OFF.

2) Remove the electronic throttle control relay.

3) Measure the resistance between electronic throttle control relay terminals.

Terminals

No. 14 — No. 15:

Is the resistance 1 M? or more?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2103 THROTTLE ACTUATOR "A" CONTROL MOTOR CIRCUIT HIGH">Go to Step 2.

Replace the electronic throttle control relay. Electronic Throttle Control Relay">

2.CHECK SHORT CIRCUIT OF ELECTRONIC THROTTLE CONTROL RELAY POWER SUPPLY.

1) Turn the ignition switch to ON.

2) Measure the voltage between electronic throttle control relay connector and chassis ground.

Connector & terminal

(B225) No. 14 (+) — Chassis ground (−):

Is the voltage 10 V or more?

Repair the short circuit to power in the harness between ECM connector and electronic throttle control relay connector.

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2103 THROTTLE ACTUATOR "A" CONTROL MOTOR CIRCUIT HIGH">Go to Step 3.

3.CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL RELAY CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from ECM.

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

Connector & terminal

(B135) No. 17 — Chassis ground:

Is the resistance 1 M? or more?

Repair the poor contact of ECM connector.

Repair the short circuit to ground in harness between ECM connector and electronic throttle control relay connector.
