Variable Induction Control Actuator: Testing and Inspection
INTAKE MANIFOLD COMMUNICATION CONTROL (IMCC) ACTUATOR INSPECTIONNOTE: 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.)
4. Connect battery positive voltage to terminal A and ground to terminal B.
5. Verify that the IMCC actuator operates.
- If not specified, replace the IMCC actuator.
- If as specified, carry out the "Circuit Open/Short Inspection".
Circuit Open/Short Inspection
1. Disconnect the negative battery cable.
2. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION.)
3. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
4. Tighten the connector bolt.
Tightening torque: 3.0 - 5.4 N.m {30 - 56 kgf.cm, 27 - 48 in.lbf}
5. Check the 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 104 pin breakout box 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 A (harness-side) and body GND
- IMCC actuator terminal B (harness-side) and power supply
- IMCC actuator terminal B (harness-side) and body GND
