INTAKE MANIFOLD COMMUNICATION CONTROL (IMCC) ACTUATOR INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513)

BME011320130203

  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 28
  - 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
