-
Using a Multimeter, check the Intake Manifold Runner Control (IMRC) Valve N316 electrical harness connector terminal 1 to ground (GND) for
voltage.
Specified value: battery voltage.
-
Switch the ignition off.
If the specified value was not obtained:
-
Check the wiring from the Intake Manifold Runner Control (IMRC) Valve N316 electrical harness connector terminal 1 to the Power Supply
Relay (terminal 30, B+) J317 terminal 87 for a short circuit to Ground (GND), or an open circuit.
-
Check the electrical harness connector for damage, corrosion, lose or broken terminals.
-
If necessary, repair the wiring connection.
If no malfunctions are found in the wiring:
Checking wiring
If the manufacturers test box is being used. Perform the following step.
-
Install the Test Box 105 Pin VAG1598/31.
If the manufacturers test box is not being used. Perform the following step.
-
Remove the Motronic Engine Control Module (ECM) J623.
-
Using a multimeter, check the Intake Manifold Runner Control (IMRC) Valve N316 electrical harness connector terminal 2 to the Engine Control
Module (ECM) J623 electrical harness connector T121 terminal 121 for an open circuit.

If the specification was not obtained:
-
Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).
-
Check the electrical harness connector for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If no malfunction is detected in the wiring:
-
Erase the DTC memory.
-
Perform a road test to verify repair.
If the DTC does not return:
Repair complete, Generate readiness code. See: Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness
Codes
-
End diagnosis.
If the DTC does return and no malfunction is detected in the wiring and the voltage supply was OK:
-
Replace the Engine Control Module (ECM) J623.
-
Assembly is performed in the reverse of the removal.
