3.
(N117) INTAKE SWIRL SERVO MOTOR CONTROL CIRCUIT OPEN OR HIGH RESISTANCE
Measure the resistance of the (N117) Intake Swirl Servo Motor Control
circuit between the Intake Swirl Servo Motor connector and the Engine
Control Module (ECM) connector.
Is the resistance below 10.0 ohms?
Yes
>> Go to 4
No
>> Repair the (N117) Intake Swirl Servo Motor Control circuit
for an open circuit or high resistance.
Perform the ECM Verification Test Ver. 1. (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING)
4.
INTAKE SWIRL SERVO MOTOR
Connect the Engine Control Module (ECM) connector.
Turn the ignition on.
With the scan tool, actuate the Intake Swirl Servo Motor (Swirl Actuator)
to 100%.
Using a 12 volt test light connected to 12 volts, check the (N117) Intake
Swirl Servo Motor Control circuit in the Swirl Solenoid harness connec-
tor.
NOTE: The test light should be illuminated and bright. Compare
the brightness to that of a direct connection to the battery.
NOTE: The circuit will remain actuated by the controller for 30 sec-
onds. Be certain the actuation is active when checking the circuit.
With the scan tool, actuate the Intake Swirl Servo Motor (Swirl Actuator)
to 0%.
Using a 12 volt test light connected to 12 volts, check the (N117) Intake
Swirl Servo Motor Control circuit in the Swirl Solenoid harness connec-
tor.
NOTE: The test light should not be illuminated.
NOTE: The circuit will remain actuated by the controller for 30 seconds. Be certain the actuation is active
when checking the circuit.
Is the test light illuminated and bright with the actuation at 100% and not illuminated with the actuation
at 0%?
Yes
>> Replace the Intake Swirl Servo Motor in accordance with the Service Information.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).
No

ENGINE CONTROL MODULE (ECM)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Intake Swirl Servo
Motor and the Engine Control Module (ECM).
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Refer to any Technical Service Bulletins that may apply.
Were any problems found?
Yes
>> Repair as necessary.
Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
No
>> Replace the Engine Control Module (ECM) in accordance with the Service Information.

•
When Monitored:
With the ignition on and the Intake Swirl Servo Motor command on.
•
Set Condition:
The ECM detects excessive current on the (N117) Intake Swirl Servo Motor Control circuit for 2.0 seconds.
Possible Causes
INTERMITTENT DTC
(N117) INTAKE SWIRL SERVO MOTOR CONTROL CIRCUIT SHORTED TO VOLTAGE
(N117) INTAKE SWIRL SERVO MOTOR CONTROL CIRCUIT SHORTED TO THE (K343) FUSED ASD RELAY
OUTPUT 2 CIRCUIT
(N117) INTAKE SWIRL SERVO MOTOR CONTROL CIRCUIT OPEN OR HIGH RESISTANCE
INTAKE SWIRL SERVO MOTOR
ENGINE CONTROL MODULE (ECM)
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.
DTC IS ACTIVE
Ignition on, engine not running.
With the scan tool, Clear DTCs in the Engine Control Module (ECM).
With the scan tool, actuate the Intake Swirl Servo Motor.
Monitor the scan tool for at least two minutes.
With the scan tool, select View DTCs.
Is the status Active for this DTC?
Yes
>> Go To 2
No
>> Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
2.
(N117) INTAKE SWIRL SERVO MOTOR CONTROL CIRCUIT SHORTED TO VOLTAGE
Turn the ignition off.
Disconnect the Intake Swirl Servo Motor connector.
Disconnect the Engine Control Module (ECM) connector.
Remove the ASD Relay from the IPM.
Connect a jumper wire between cavity 30 and cavity 87 of the ASD
Relay Connector.
Turn the ignition on.
Measure the voltage of the (N117) Intake Swirl Servo Motor Control cir-
cuit in the Intake Swirl Servo Motor connector.
Is there any voltage present?
Yes
>> Repair the (N117) Intake Swirl Servo Motor Control circuit
for a short to voltage.
Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
No
