Diagnostic Test

Read the HIGH-VOLTAGE SAFETY PROCEDURES. Refer to  HIGH VOLTAGE SAFETY PROCEDURES  . 

When the HIGH-VOLTAGE POWER-DOWN PROCEDURE is necessary. Refer to  VEHICLE HIGH VOLTAGE POWER DOWN  . 

1. With the scan tool, read Integrated Dual Charge Module (IDCM) DTCs and record on the repair order.
2. Record the Environmental Data, Snap-Shot Data and any DTCs.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data and Snap-Shot Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read IDCM DTCs.

   Did the DTC return?

   Yes 

   • Go To  2

   No 

   • Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .

1. Using the approved Mopar® Battery Tester/Charger Station, test the 12.0 Volt Battery.

   Did the 12.0 Volt Battery pass the load test?

   Yes 

   • Go To  3

   No 

   • Follow the repair on the tester and charge or replace the 12.0 Volt Battery in accordance with the Service Information. Refer to BATTERY [ELA], REMOVAL AND INSTALLATION .
   • Perform the INTEGRATED DUAL CHARGE MODULE (IDCM) VERIFICATION TEST. Refer to INTEGRATED DUAL CHARGE MODULE (IDCM) VERIFICATION TEST .

1. Disconnect the component harness connector to isolate the 12.0 volt supply circuit.
2. Connect the positive lead of the load test tool to the 12.0 volt supply circuit at the component harness connector (A). Note:  refer to the diagram below.
3. Connect the negative lead of the load test tool to the ground circuit of the Battery or a good chassis ground.
4. Make sure that the circuit being tested is being powered on. If the 12.0 volt circuit being tested is an ignition feed for example, the ignition must be on. If testing an output from a relay, verify that the relay is energized and on.
5. The bulb on the load test tool should be illuminated and bright if there is no resistance in the circuitry.
   NOTE:

   Why load test a circuit? A load test is used to determine if a circuit is capable of carrying the amperage needed to perform properly. The 3156 bulb in the load tool illustrated, is a simple but effective method of testing circuit functionality. A 3156 Bulb has approximately 6.0 Ohms of resistance when the bulb is powered and draws approximately 2.0 amps of current. Read the CIRCUIT LOAD TESTING PROCEDURE for information on building a simple load test tool and for additional load testing information and alternative methods of load testing or voltage drop testing a circuit. Refer to  CIRCUIT LOAD TESTING PROCEDURES  .
