Diagnostic Procedure

2000 Dodge and Ram Intrepid R/TSECTION Diagnostic Procedure
  1. Using scan tool, check STARTS SINCE SET counter. If counter is set at 3 or less, go to next step. If counter is not set at 3 or less, go to step  10.
  2. Turn ignition off. Disconnect Autostick switch harness connector located under gearshift lever. Turn ignition on. Measure voltage between ground and Autostick downshift switch sense circuit (terminal No. 1) and between ground and upshift switch sense circuit (terminal No. 2) at Autostick switch harness connector. See WIRING DIAGRAMS . If voltage is greater than 10 volts on both circuits, replace Autostick switch. If voltage is 10 volts or less, go to next step.
  3. Measure voltage between ground and fused ignition switch output circuit at Autostick switch harness connector terminal No. 4. If voltage is greater than 10 volts, go to next step. If voltage is 10 volts or less, repair open in fused ignition switch output circuit.
  4. Turn ignition off. Measure resistance between ground and ground circuit at Autostick switch harness connector terminal No. 3. If resistance is greater than 5 ohms, repair open ground circuit. If resistance is 5 ohms or less, go to next step.
  5. Disconnect TCM harness connector. See Figure. Measure resistance of Autostick downshift switch sense circuit between Autostick switch harness connector terminal No. 1 and TCM harness connector terminal No. 44. See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open in Autostick downshift switch sense circuit. If resistance is 5 ohms or less, go to next step.
  6. Measure resistance between ground and Autostick downshift switch sense circuit at TCM harness connector terminal No. 44. If resistance is less than 5 ohms, repair Autostick downshift sense circuit for a short to ground. If resistance is 5 ohms or greater, go to next step.
  7. Measure resistance of Autostick upshift switch sense circuit between Autostick switch harness connector terminal No. 2 and TCM harness connector terminal No. 5. See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open in Autostick upshift switch sense circuit. If resistance 5 ohms or less, go to next step.
  8. Measure resistance between ground and Autostick upshift switch sense circuit at TCM harness connector terminal No. 5. If resistance is less than 5 ohms, repair Autostick upshift sense circuit for a short to ground. If resistance is 5 ohms or greater, go to next step.
  9. Turn ignition on. Using scan tool, activate Autostick switch status. Shift into Autostick. Pull gearshift lever to the left several times to actuate downshift switch, then push gearshift lever to the right several times to actuate upshift switch. If upshift and downshift switch status on scan tool display toggles, test is complete. If switch status on scan tool display does not toggle, replace TCM.
  10. Check for low battery voltage or charging system problems. Check TCM power and ground circuits for intermittent shorts or high resistance. Conditions necessary to set DTC are not present at this time. Using appropriate wiring diagram as a guide, inspect wiring and connectors associated with circuits in question. See WIRING DIAGRAMS . Wiggle wires while checking for shorted and open circuits. Repair as necessary. If circuits are okay, testing is complete.

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.
