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.

CHECK FOR AN ACTIVE DTC
1. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
2. With the scan tool, read DTCs and record on the repair order.
  Is the DTC active or pending?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION . .
FUEL INJECTOR 5 WIRING AND CONNECTOR INSPECTION
1. Turn the ignition off.
2. Verify that the connector is properly connected to the injector.
3. Disconnect the Fuel Injector harness connector and inspect the wiring and terminals for any condition that would result in a poor connection.
4. Look for any chafed, pierced, pinched, or partially broken wires.
5. Look for broken, bent, pushed out or corroded terminals.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  No
  - Go To 3
CHECK THE (F342) FUSED ASD RELAY OUTPUT CIRCUIT FOR AN OPEN/HIGH RESISTANCE
1. Using a 12-volt test light connected to ground, probe the (F342) Fused ASD Relay Output circuit in the Fuel Injector 5 harness connector.
2. Turn the ignition on.
  NOTE:
  The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright?
  
  Yes
  - Go To 4
  No
  - Repair the (F342) Fused ASD Relay Output circuit for an open or high resistance. If the fuse is found to be blown, check the (F342) Fused ASD Relay Output circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
CHECK THE (K38) INJECTOR 5 CONTROL CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
3. Check for continuity between ground and the (K38) Injector 5 Control circuit at the Fuel Injector harness connector.
  Is there continuity between ground and the (K38) Injector 5 Control circuit?
  
  Yes
  - Repair the (K38) Injector 5 Control circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  No
  - Go To 5
CHECK THE (K38) INJECTOR 5 CONTROL CIRCUIT FOR AN OPEN/HIGH RESISTANCE
CAUTION:
Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the GPEC Diagnostic Adaptor to perform the diagnosis.
1. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
2. Measure the resistance of the (K38) Injector 5 Control circuit between the Fuel Injector harness connector and the GPEC Adaptor.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 6
  No
  - Repair the (K38) Injector 5 Control circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .

CHECK THE FUEL INJECTOR 5 CIRCUIT RESISTANCE

Measure the resistance of Fuel Injector 5.

NOTE:

The resistance of the Fuel Injector will vary according to the temperature of the injector coil. Use the table below to determine the resistance range of the injector.

Fuel Injector Coil Resistance Based on Engine Temperature
Temperature	Resistance
-20°C (-4°F)	10 Ohms (+/- 0.6 Ohms)
20°C (68°F)	12 Ohms (+/- 0.6 Ohms)
60°C (140°F)	14 Ohms (+/- 0.6 Ohms)
100°C (212°F)	16 Ohms (+/- 0.6 Ohms)

Is the resistance of the Fuel Injector within the specified range?

Yes

Go To 7

Replace the Fuel Injector in accordance with the Service Information. Refer to INJECTOR(S), FUEL, REMOVAL .
Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .

CHECK RELATED PCM AND COMPONENT CONNECTIONS
1. Perform any Service Bulletins that apply.
2. Disconnect all PCM harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.
5. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
9. With the scan tool, erase DTCs.
10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
11. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Replace the Powertrain Control Module in accordance with the Service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  No
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  - Test complete.
