HINT

1. The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine does not crank, proceed to the problem symptoms table. Refer to «REMOVAL»(ref-396649-S41403644072011050900000) .
2. Read freeze frame data using Techstream. The TCM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction. Refer to «FREEZE FRAME DATA»(ref-396630-S23203956252011050900000) .

HINT

Using 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.

1. READ DATA LIST Turn the engine switch off. Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn on the tester. Select the item "Powertrain / ECT / Data List". According to the display on the tester, 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 position is; P and N: ON Except P and N: OFF When the shift lever position displayed on Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect. Shift SW Status (R Range) PNP switch status / ON or OFF Shift lever position is; R: ON Except R: OFF When the shift lever position displayed on Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect. Shift SW Status (D Range) PNP switch status / ON or OFF Shift lever position is; D and S: ON Except D and S: OFF When the shift lever position displayed on Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.

1. ACTIVE TEST HINT: Using Techstream to perform Active Test allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Test early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Test. Warm up the engine. Turn the engine switch off. Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn on the tester. Enter the following items: "Powertrain / ECT / Active Test". According to the display on the tester, perform "Active Test".
