Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
  1. With the ignition ON, observe the transmission ISS/OSS supply voltage circuit status on the scan tool, the parameter should display OK.
    • If the circuit status does not display OK, disconnect the ISS/OSS connector from the control solenoid (w/body and TCM) valve assembly and recheck the scan tool display.
    • If the transmission ISS/OSS supply voltage circuit status still displays OK, visually inspect the ISS, harness, connector, the control solenoid (w/body and TCM) valve assembly pins for metallic debris and 1-2-3-4 and 3-5-R clutch housing machined teeth surface for damage or misalignment. Repair or replace any damaged components.
  2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test . The scan tool should display Transmission ISS between 100-400 RPM.
    • If 100-400 RPM ISS RPM is displayed, replace the ISS/OSS assembly.
    • If no ISS RPM is displayed or the RPM is out of range, replace the control solenoid (w/body and TCM) valve assembly.
