Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

NO START PRE-TEST
NOTE:
Verify no codes are set in the Occupant Restraint Controller. If codes are present, they may be the cause of a No Start condition.

NOTE:
The following list of items must be checked before continuing with any no start tests.
1. The battery must be fully charged and in good condition. A low charged battery may produce invalid test results. If the battery is low, charge the battery and then attempt to start the vehicle by cranking the engine for 15 seconds, three consecutive times. This will allow any DTCs to set that may have been erased due to a dead battery.
2. Try to communicate with the PCM using a scan tool. If communication between the scan tool and PCM is not allowed, inspect fuses. If the fuses appear OK, for the No Response from PCM diagnostic procedure. Refer to DIAGNOSIS AND TESTING .
3. Read the PCM DTCs with the scan tool. If any DTCs are present, they must be repaired before continuing with any other No Start diagnostic tests. For the related P-code that is reported by the PCM, refer to appropriate Testing & Diagnostics article in Engine Performance .
4. Make sure that the Communication Bus is functional. Attempt to communicate with other modules on the CAN C bus. If you are unable to establish communication with any modules, for the Diagnostic CAN C diagnostic procedures. Refer to DIAGNOSIS AND TESTING .
5. The vehicles security module must be operating properly. Check for DTCs that may be stored in the vehicles security module. Repair the DTCs before continuing.
6. If no DTCs are found, using the scan tool, select Clear PCM (BATT Disconnect).
7. Crank the engine several times. Using the scan tool, View DTCs. If a DTC is present go to and perform the appropriate diagnostic procedure before continuing.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to appropriate Testing & Diagnostics article in Engine Performance .
  No
  - Go To Step 2
OPEN FUSE
1. Check for any open fuses that may be related to the No Start condition.
  Are any of the fuses open?
  
  Yes
  - Check the related circuit(s) for a short to ground and replace the open fuse.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to appropriate Testing & Diagnostics article in Engine Performance .
  No
  - Go To Step 3
FUEL DELIVERY
1. Verify that the Fuel tank is not empty before continuing.
2. Perform the CHECKING THE FUEL DELIVERY SYSTEM in DIAGNOSIS AND TESTING .
  Was the No Start condition solved after following the CHECKING THE FUEL DELIVERY SYSTEM diagnostic procedure?
  
  Yes
  - Test Complete.
  No
  - Go To Step 4
IGNITION SYSTEM
1. Perform the CHECKING THE IGNITION COIL OPERATION in DIAGNOSIS AND TESTING .
  Was the No Start condition solved after following the CHECKING THE IGNITION COIL OPERATION diagnostic procedure?
  
  Yes
  - Test Complete.
  No
  - Go To Step 5
ENGINE MECHANICAL
1. Check for any of the following conditions/mechanical problems:
  - ENGINE COMPRESSION - must be within specifications.
  - ENGINE EXHAUST SYSTEM - must be free of any restrictions or leaks.
  - ENGINE VALVE TIMING - must be within specifications, check for broken timing components
  Are there any engine mechanical problems?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to appropriate Testing & Diagnostics article in Engine Performance .
  No
  - Go To Step 6
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the related Sensors and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related Sensors and the Powertrain Control Module connectors.
4. Refer to any Technical Service Bulletins (TSBs) that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to appropriate Testing & Diagnostics article in Engine Performance .
  No
  - Replace and program the Powertrain Control Module in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to appropriate Testing & Diagnostics article in Engine Performance .
