INTAKE MANIFOLD COMMUNICATION CONTROL (IMCC) ACTUATOR INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

Note

• Perform the following test only when directed.

IMCC Actuator Operation Test

1. Disconnect the negative battery cable.

2. Disconnect the IMCC actuator connector.

3. Remove the IMCC actuator. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [AJ].)

4. Connect battery positive voltage to terminal A and ground to terminal B as shown.

5. Verify that the IMCC actuator operates as shown.

• If not specified, replace the IMCC actuator.

• If as specified, carry out the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection

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

2. Check 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.

- IMCC actuator terminal B (harness-side) and PCM terminal 97

- IMCC actuator terminal A (harness-side) and main relay (harness-side) terminal D

Short circuit

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

- IMCC actuator terminal B (harness-side) and power supply

- IMCC actuator terminal B (harness-side) and body GND
