RAM 2500 Truck 2WD L6-6.7L DSL Turbo (2010)
NOTE: The connector displayed in the graphics are only an example.
1. Turn the ignition off.
2. Disconnect the wire harness connector of the component that is being tested.
NOTE: Check connectors - Clean/repair as necessary.
3. At this time leave all in-line connectors connected.
4. Use a multimeter set to measure DC voltage.
5. Connect the ground lead of the meter to a known good ground circuit.
6. Use the positive lead of the multimeter and probe the circuit you are checking for voltage.
7. Ignition on, engine not running.
Is the voltage within specifications for this circuit?
Yes
-
The circuit is functioning properly or the condition that originally caused the open or short may not be present at this time. Continue to measure
the voltage and wiggle the wire harness and connectors while checking for an intermittent open or short.
-
Use the wiring application as a guide to trace the circuits and look for any in-line connectors where the short could occur intermittently.
-
Look for any chafed, pierced, pinched, or partially broken wires.
-
Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related wire harness connectors.
-
Perform any Technical Service Bulletins that may apply.
No
-
Repair the open or short to ground in the circuit. Use the wiring application as a guide to trace the circuits and look for any in-line connectors
where the short could occur.
-
One way to help isolate the open or short is to disconnect any in-line connectors that the circuit being checked runs through and check for the
voltage again. If the voltage is present, the open or short is on the other side of the in-line connector.
2. CHECKING FOR A SHORT TO BATTERY VOLTAGE USING A MULTIMETER
1. Turn the ignition off.
2. Disconnect the wire harness connectors of the components that contain the circuit that is suspected as having a short.
