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
