Diagnostic Test

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

ACTIVE DTC
NOTE: Diagnose any Misfire DTCs before continuing.
1. Ignition on, engine not running.
2. With a scan tool, read DTCs.
  NOTE: Diagnose any Deactivation or Oil Pressure DTCs before continuing with this test.
  
  Is the DTC active at this time?
  
  Yes
  - Go to step 2
  No
  - Perform the CHECKING FOR AN INTERMITTENT DTC. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
MDS SOLENOID 4
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. Remove the Intake Manifold per Service Information.
3. Turn the ignition on.
4. With the scan tool actuate the MDS Solenoid 4.
  Can you feel and hear the Solenoid Actuating?
  
  Yes
  - Go to step 3
  No
  - Remove the Solenoid and check for any debris that may be blocking the oil passages to the Solenoid. If the passages are clogged, clean the passages and replace the MDS Solenoid 4. If the passages are not clogged with debris, replace the MDS Solenoid 4.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
MDS SOLENOID 6
NOTE: The DTC must not be active for the actuator test to operate properly, clear all DTC before continuing.
1. With the scan tool actuate the MDS Solenoid 6.
  Can you feel and hear the Solenoid Actuating?
  
  Yes
  - Go to step 4
  No
  - Remove the Solenoid and check for any debris that may be blocking the oil passages to the Solenoid. If the passages are restricted, clean the passages and replace the MDS Solenoid 6. If the passages are unable to be cleaned out, replacing the engine block may be necessary. If the passages are not clogged with debris, replace the MDS Solenoid 6.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
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 per Service Information.
4. Remove the each pair of lifters for Cylinders 4 and 6.
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.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Replace both sets of lifters if no other possible causes remain.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
