IDLE AIR CONTROL (IAC) VALVE INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513)

Note

• Perform the following test only when directed.

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [AJ].)

2. Inspect the following wiring harnesses for open or short (continuity check).

Open circuit

• If there is no continuity, the circuit is open. Repair or replace the harness.

- IAC valve terminal A (harness-side) and PCM terminal 54

- IAC valve terminal B (harness-side) and PCM terminal 83

Short circuit

• If there is continuity, the circuit is short. Repair or replace the harness.

- IAC valve terminal A (harness-side) and power supply

- IAC valve terminal A (harness-side) and GND

- IAC valve terminal B (harness-side) and power supply

- IAC valve terminal B (harness-side) and GND

Operation Test

1. Carry out the "Idle Air Control Inspection". (See Idle Air Control Inspection.)

• If not as specified, perform the further inspection for the IAC valve.

Resistance Inspection

1. Disconnect the negative battery cable.

2. Disconnect the IAC valve connector.

3. Measure the resistance between the IAC valve terminals using an ohmmeter.

• If not as specified, replace the IAC valve. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [AJ].)

• If as specified but the Operation Test is failed, carry out the "Circuit Open/Short Inspection".
