RAM 2500 Truck 4WD V8-5.7L VIN D (2005)
Q: Is the resistance below 30.0 ohms on any of the circuits?
YES: Go To 13
NO: Go To 14
13. CHECK THE DOOR DRIVER CIRCUITS WHOSE RESISTANCE WAS BELOW 30.0 OHMS IN THE PREVIOUS STEP FOR A
SHORT TO THE (C34) COMMON DOOR DRIVER CIRCUIT
Disconnect all door actuator harness connectors whose circuit resistance was below 30.0 ohms.
Measure the resistance between the (C34) Common Door Driver circuit and each applicable door driver circuit in the A/C Heater Control C1
harness connector.
Q: Is the resistance below 10k ohms on any of the circuits?
YES: Repair the door driver circuits with a resistance below 10k ohms for a short to the (C34) Common Door Driver circuit. Perform BODY
VERIFICATION TEST - VER 1. See: Testing and Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Body
Verification Test
NO: Replace all door actuators with a resistance below 30.0 ohms. Perform BODY VERIFICATION TEST - VER 1. See: Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Body Verification Test
14. RUN THE ACTUATOR CIRCUIT TEST
Reconnect the A/C Heater Control C1 harness connector.
Turn the ignition on.
With the DRBIII(R) in HVAC, select System Tests and then select Actuator Circuit Test.
Allow the test to run to completion before proceeding.
Q: What message does the DRBIII(R) display?
Same message as from start of test
Replace the A/C Heater Control. Perform BODY VERIFICATION TEST - VER 1. See: Testing and Inspection/Diagnostic Trouble Code
Tests and Associated Procedures/Verification Tests/Body Verification Test
Different message than from start of test
Using the wiring diagram as a guide, inspect the wiring and connectors for conditions causing an intermittent short that set the original test
message. Repair as necessary. If the DRBIII(R) displays a message for a different door driver circuit, return to Test 1 of this diagnostic
procedure. Perform BODY VERIFICATION TEST - VER 1. See: Testing and Inspection/Diagnostic Trouble Code Tests and Associated
Procedures/Verification Tests/Body Verification Test
