2001 Dodge and Ram Intrepid BaseFACTORY OEM SERVICE PROCEDURE

Bus +/- Signals Open From Body Control Module

NOTE: After making any repairs, perform BODY CONTROL MODULES SYSTEM VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition off. Disconnect junction block connector C2. See Figure . Measure resistance between ground and junction block connector C2 terminal No. 8, ground circuit (Black/Orange wire). See Fig 1 . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black/Orange wire.
  2. Disconnect junction block connector C3. Measure resistance between ground and junction block connector C3 terminal No. 4, ground circuit (Black/Light Green wire). See Fig 2 . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black/Light Green wire.
  3. Ensure ignition is off. Remove Body Control Module (BCM) from back of junction block. Using a 12-volt test light connected to ground, probe terminal No. 7, fused B+ circuit at BCM connector on back of junction block. If test light illuminates, leave BCM removed, and go to next step. If test light does not illuminate, replace junction block.
  4. Connect junction block connector C2. Measure resistance between ground and terminal No. 1, ground circuit at BCM connector on back of junction block. If resistance is less than 5 ohms, leave BCM removed, and go to next step. If resistance is 5 ohms or more, replace junction block.
  5. Connect junction block connector C3. Measure resistance between ground and terminal No. 20, ground circuit at BCM connector on back of junction block. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, replace junction block.
  6. Disconnect BCM connector C1. Measure resistance between ground and Data Link Connector (DLC) terminal No. 2, PCI bus circuit (Violet/Yellow wire). See Fig 3 . If resistance is more than 100 ohms, go to next step. If resistance is 100 ohms or less, repair short to ground in Violet/Yellow wire.
  7. Turn ignition on. Measure voltage on DLC terminal No. 2, PCI bus circuit (Violet/Yellow wire). If voltage does not exist, go to next step. If voltage exists, repair short to voltage in Violet/Yellow wire.
  8. Measure resistance in PCI bus circuit (Violet/Yellow wire) between DLC terminal No. 2 and BCM connector C1 terminal No. 14. See Figure and Fig 3 . If resistance is less than 5 ohms, replace BCM. If resistance is 5 ohms or more, repair open in Violet/Yellow wire.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
