Diagnostic Procedure

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using scan tool, perform SHIFT LEVER POSITION test. If test passes, go to next step. If test fails with an error DTC, go to step  3. If test fails without an error DTC, go to step  22.
  2. Conditions necessary to set DTC are not present at this time. Using 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.
    3. NOTE: Failure to remove starter relay can cause a NO RESPONSE FROM PCM condition.
  3. Remove starter relay from power distribution center. See Figure. This prevents vehicle from starting in gear. Install Transmission Simulator (8333). Turn ignition on. Perform SHIFT LEVER POSITION test. When scan tool instructs to place gearshift lever in a particular position, do so using transmission simulator. The LED for gear position in question must be illuminated before selecting ENTER on scan tool. If test passes, disconnect transmission simulator, and go to next step. If test does not pass, go to step  5.
  4. Repair internal transaxle problem. See appropriate OVERHAUL article. Replace TR sensor. See REMOVAL & INSTALLATION in appropriate SERVICING article in AUTOMATIC TRANSMISSIONS.
  5. Using scan tool, monitor TRS sense circuits C1-C4 while moving gearshift lever from "P" position to "L" position, pausing momentarily in each gear position. If TRS T1 sense circuit (C4) does not change state, go to next step. If TRS T3 sense circuit (C3) does not change state, go to step  10. If TRS T41 sense circuit (C1) does not change state, go to step  14. If TRS T42 sense circuit (C2) does not change state, go to step  18.
  6. Turn ignition off. Disconnect PCM harness connector C4. See Figure. Disconnect TR sensor harness connector. Measure resistance of TRS T1 sense circuit between TR sensor harness connector terminal No. 7 and PCM harness connector C4 terminal No. 15 using Miller Special Tool (8815). See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open circuit. If resistance is 5 ohms or less, go to next step.
  7. Measure resistance between ground and TRS T1 sense circuit at PCM harness connector C4 terminal No. 15 using Miller Special Tool (8815). If resistance is less than 5 ohms, repair circuit for short to ground. If resistance is 5 ohms or greater, go to next step.
  8. Remove transmission control relay from power distribution center. See Figure. Using fused jumper wire, jumper fused B+ circuit and transmission control relay output circuit together at transmission control relay connector. See WIRING DIAGRAMS . Turn ignition on. Measure voltage between ground and TRS T1 sense circuit at PCM harness connector C4 terminal No. 15 using Miller Special Tool (8815). If voltage is greater than .5 volt, repair circuit for short to voltage. If voltage is not as specified, go to next step.
  9. If no other potential causes for DTC P0706 remain, PCM is assumed to be faulty. Repair or replace as necessary. See POWERTRAIN CONTROL MODULE  under REMOVAL & INSTALLATION.
  10. Turn ignition off. Disconnect PCM harness connector C4. See Figure. Disconnect TR sensor harness connector. Measure resistance of TRS T3 sense circuit between TR sensor harness connector terminal No. 8 and PCM harness connector C4 terminal No. 16 using Miller Special Tool (8815). See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open circuit. If resistance is 5 ohms or less, go to next step.
  11. Measure resistance between ground and TRS T3 sense circuit at PCM harness connector C4 terminal No. 16 using Miller Special Tool (8815). If resistance is less than 5 ohms, repair circuit for short to ground. If resistance is 5 ohms or greater, go to next step.
  12. Turn ignition off. Remove transmission control relay from power distribution center. See Figure. Connect jumper wire between fused B+ circuit and transmission control relay output circuit at transmission control relay connector. See WIRING DIAGRAMS . Turn ignition on. Measure voltage between ground and TRS T3 sense circuit at PCM harness connector C4 terminal No. 16 using Miller Special Tool (8815). If voltage is greater than .5 volt, repair circuit for short to voltage. If voltage is not as specified, go to next step.
  13. If no other potential causes for DTC P0706 remain, PCM is assumed to be faulty. Repair or replace as necessary. See POWERTRAIN CONTROL MODULE  under REMOVAL & INSTALLATION.
  14. Turn ignition off. Disconnect PCM harness connector C4. See Figure. Disconnect TR sensor harness connector. Measure resistance of TRS T41 sense circuit between TR sensor harness connector terminal No. 10 and PCM harness connector C4 terminal No. 27 using Miller Special Tool (8815). See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open circuit. If resistance is 5 ohms or less, go to next step.
  15. Measure resistance between ground and TRS T41 sense circuit at PCM harness connector C4 terminal No. 27 using Miller Special Tool (8815). If resistance is less than 5 ohms, repair circuit for short to ground. If resistance is 5 ohms or greater, go to next step.
  16. Turn ignition off. Remove transmission control relay from power distribution center. See Figure. Connect jumper wire between fused B+ circuit and transmission control relay output circuit at transmission control relay connector. See WIRING DIAGRAMS . Turn ignition on. Measure voltage between ground and TRS T41 sense circuit at PCM harness connector C4 terminal No. 27 using Miller Special Tool (8815). If voltage is greater than .5 volt, repair circuit for short to voltage. If voltage is not as specified, go to next step.
  17. If no other potential causes for DTC P0706 remain, PCM is assumed to be faulty. Repair or replace as necessary. See POWERTRAIN CONTROL MODULE  under REMOVAL & INSTALLATION.
  18. Turn ignition off. Disconnect PCM harness connector C4. See Figure. Disconnect TR sensor harness connector. Measure resistance of TRS T42 sense circuit between TR sensor harness connector terminal No. 9 and PCM harness connector C4 terminal No. 37 using Miller Special Tool (8815). See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open circuit. If resistance is 5 ohms or less, go to next step.
  19. Measure resistance between ground and TRS T42 sense circuit at PCM harness connector C4 terminal No. 37 using Miller Special Tool (8815). If resistance is less than 5 ohms, repair circuit for short to ground. If resistance is 5 ohms or greater, go to next step.
  20. Turn ignition off. Remove transmission control relay from power distribution center. See Figure. Connect jumper wire between fused B+ circuit and transmission control relay output circuit at transmission control relay connector. See WIRING DIAGRAMS . Turn ignition on. Measure voltage between ground and TRS T42 sense circuit at PCM harness connector C4 terminal No. 37 using Miller Special Tool (8815).

  21. If no other potential causes for DTC P0706 remain, PCM is assumed to be faulty. Repair or replace as necessary. See POWERTRAIN CONTROL MODULE  under REMOVAL & INSTALLATION.
  22. Check and adjust gearshift linkage. See ADJUSTMENTS in appropriate SERVICING article in AUTOMATIC TRANSMISSIONS.
