MPV LX V6-2.5L DOHC (2000)
Variable Induction Control Module: Testing and Inspection
INTAKE MANIFOLD RUNNER CONTROL (IMRC) ACTUATOR INSPECTION
Note: Perform the following test only when directed.
IMRC Actuator Simulation Test
1. Carry out the "IMRC Inspection". See: Powertrain Management/Computers and Control Systems
-
If the Simulation Test is failed, carry out the "Circuit Open/Short Inspection".
Circuit Open/Short Inspection
1. Disconnect the negative battery cable.
2. Disconnect the PCM connector.
3. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
4. Tighten the connector bolt.
Tightening torque: 7.9 - 10.7 Nm (80 - 110 kgf-cm, 69.5 - 95.4 inch lbs.)
5. Check the following wiring harness for open or short (continuity check).
Open circuit
-
If there is no continuity, the circuit is open. Repair or replace the harness.
-
IMRC actuator terminal 1 (harness-side) and 104 pin breakout box terminal 42
-
IMRC actuator terminal 3 (harness-side) and body ground
-
IMRC actuator terminal 5 (harness-side) and 104 pin breakout box terminal 3
-
IMRC actuator terminal 6 (harness-side) and 104 pin breakout box terminal 91
-
IMRC actuator terminal 2 (harness-side) and main relay terminal D (harness-side)
Short circuit
-
If there is continuity, the circuit is short. Repair or replace the harness.
-
IMRC actuator terminal 2 (harness-side) and body ground
-
IMRC actuator terminal 1 (harness-side) and body ground
-
IMRC actuator terminal 1 (harness-side) and power supply
-
IMRC actuator terminal 5 (harness-side) and body ground
-
IMRC actuator terminal 5 (harness-side) and power supply
-
IMRC actuator terminal 6 (harness-side) and power supply
