INSPECTION PROCEDURE

Note. Perform the universal trip to clear permanent DTCs. Refer to DTC CHECK / CLEAR . Inspect the fuses for circuits related to this system before performing the following inspection procedure.

  1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not. Warm up the engine. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data. Follow the instructions on the Techstream and read the Data List. Tester Display Measurement Item/Range Normal Condition Diagnostic Note Neutral Position SW Signal PNP switch status/ ON or OFF Shift lever: In P or N: ON Not in P or N: OFF When shift lever position displayed on Techstream differs from actual position, adjustment of PNP switch or shift cable may be incorrect.
