Circuit/System Testing

NOTE: Do not connect an external voltage to any control solenoid (w/body and TCM) valve assembly terminal, and avoid the inadvertent shorting of terminals.
  1. Ignition OFF, remove the control valve body cover. Refer to CONTROL VALVE BODY COVER REPLACEMENT .
  2. Connect the TCM harness connector.
  3. Disconnect the IMS connector at the control solenoid (w/body and TCM) valve assembly.
  4. Ignition ON, verify the scan tool IMS A/B/C/P parameter displays HI for all four signal circuits.
    • If not the specified value, replace the control solenoid (w/body and TCM) valve assembly.
  5. Connect a 3-amp fused jumper wire between each transmission range signal circuit terminal listed below and the IMS ground circuit, terminal A. The appropriate scan tool IMS A/B/C/P parameter should display LOW when the terminal is connected to the IMS ground.
    • Switch Signal A terminal E
    • Switch Signal B terminal D
    • Switch Signal C terminal C
    • Switch Signal P terminal B
    • If not the specified value, replace the control solenoid (w/body and TCM) valve assembly.
  6. If all circuits test normal, test or replace the IMS.
