Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
NOTE:
Diagnose any Misfire DTCs before continuing.
1. Ignition on, engine not running.
2. With a scan tool, read the DTCs.
  Is the DTC active at this time?
  
  Yes
  - Go To 2.
  No
  - Refer to STANDARD PROCEDURE and perform the INTERMITTENT CONDITION diagnostic procedure.

1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
3. Disconnect the C101 inline harness connector. The connector is located behind the left cylinder head.
4. Turn the ignition on.
5. Measure the voltage on (K453) MDS Solenoid No. 6 Control circuit in the C101 inline harness connector.
  Is voltage present?
  
  Yes
  - Repair the short to voltage in the (K453) MDS Solenoid No. 6 Control circuit.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
  No
  - Go To 3.

MDS SOLENOID RESISTANCE

Turn the ignition off.

Measure the resistance between the Ground circuit and the (K453) MDS Solenoid No. 6 Control circuit in the C101 harness connector (MDS Side).

NOTE:

It is important to follow the below temp/resistance values to ensure an accurate reading.

MDS SOLENOID RESISTANCE
TEMPERATURE VALUE	RESISTANCE - MINIMUM	RESISTANCE - MAXIMUM
-18° C (0° F)	7.22 ?	8.12 ?
0° C (32° F)	7.92 ?	8.82 ?
20° C (68° F)	8.72 ?	9.62 ?
38° C (100° F)	9.42 ?	10.32 ?
66° C (150° F)	10.62 ?	11.52 ?
93° C (200° F)	11.82 ?	12.72 ?
121° C (250° F)	12.82 ?	13.72 ?
149° C (300° F)	14.02 ?	14.92 ?

Is the resistance within an acceptable range?

Yes

Go To 4.

Visually and Physically inspect the wiring harness between the C101 connector and the MDS Solenoid connector. Repair as necessary. If OK, replace the MDS Solenoid in accordance with the Service Information. Refer to SOLENOID, MULTIPLE DISPLACEMENT [ESG], REMOVAL .
Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.

NOTE:
The DTC must not be active for the actuator test to operate properly, clear all DTC before continuing.
1. Turn the ignition off.
2. Reconnect the PCM C2 harness connector.
3. Disconnect the C101 harness connector.
4. Ignition on, engine not running.
5. Using a 12-volt test light connected to the Ground circuit, probe the (K453) MDS Solenoid No. 6 Control circuit in the C101 harness connector (PCM side).
6. With a scan tool, actuate the MDS Solenoid.
  Does the 12-volt test light flash on and off?
  
  Yes
  - Go To 5.
  No
  - Replace and program the Powertrain Control Module in accordance with the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
MDS SOLENOID 6

1. Turn the ignition off.
2. Remove the Intake Manifold in accordance with the service information. Refer to MANIFOLD, INTAKE, REMOVAL .
3. Turn the ignition on.
4. With the scan tool actuate the MDS Solenoid 6.
  Can you feel and hear the Solenoid Actuating?
  
  Yes
  - Go To 6.
  No
  - Remove the Solenoid (1) and check for any debris that may be blocking the oil passages (3) to the Solenoid. If the passages are clogged, clean the passages and replace the MDS Solenoid 6. If the passages are not clogged with debris, replace the MDS Solenoid 6.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
OIL PASSAGES RESTRICTED
1. Turn the ignition off.
2. Remove both Solenoids on Bank 2 of the engine block.
3. Remove the Bank 2 Cylinder Head in accordance with the service information. Refer to CYLINDER HEAD, REMOVAL .
4. Remove the Lifters from the right engine bank.
5. Inspect the oil passages to the Solenoids and from the Solenoids to the lifters.
  Are the passages blocked?
  
  Yes
  - Clean the oil passages as necessary. If the entire engine is restricted disassembly of the entire engine block may be necessary.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
  No
  - Replace both sets of lifters if no other possible causes remain. Refer to LIFTER(S), HYDRAULIC, ROLLER, REMOVAL .
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
