DATA LIST / ACTIVE TEST [07/2013 - 12/2013]

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 following table, 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. Connect the Techstream to the DLC3. Turn the ignition switch ON. Turn the Techstream on. Enter the following menus: Body Electrical / Main Body / Data List. Read the Data List according to the display on the Techstream. MAIN BODY Tester Display Measurement Item/Range Normal Condition Diagnostic Note D Door Courtesy SW Driver side door courtesy light switch signal/ON or OFF ON: Driver side door closed OFF: Driver side door open - P Door Courtesy SW Passenger side door courtesy light switch signal/ON or OFF ON: Passenger side door closed OFF: Passenger side door open - Luggage Courtesy SW Luggage compartment door courtesy switch signal/ON or OFF ON: Luggage compartment door open OFF: Luggage compartment door closed - IG SW Ignition switch ON signal/ON or OFF ON: Ignition switch ON OFF: Ignition switch off - ACC SW Ignition switch ACC signal/ON or OFF ON: Ignition switch ACC OFF: Ignition switch off - Room Light Output Map light assembly output signal/ON or OFF ON: Map light assembly on OFF: Map light assembly off - Key Illumination Output Ignition key cylinder light output signal/ON or OFF ON: Ignition key cylinder light on OFF: Ignition key cylinder light off - Lighting Time Lighting time of the delay control function (illuminated entry system)/15s, 7.5s or 30s 15s: 15 seconds 7.5s: 7.5 seconds 30s: 30 seconds Customized value is displayed I/L when ACC OFF Function that lights up the interior lights when the ignition switch is turned from on (ACC or IG) to off/OFF or ON OFF: Function disabled ON: Function enabled Customized value is displayed I/L ON W/Door Key Unlock Function that lights up the interior lights when the doors are unlocked/OFF or ON OFF: Function disabled ON: Function enabled Customized value is displayed Interior Light Control Operation of the illuminated entry system/OFF or ON OFF: System not operated ON: System operated Customized value is displayed
2. ACTIVE TEST HINT: Using the Techstream to perform Active Tests 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 Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Connect the Techstream to the DLC3. Turn the ignition switch ON. Turn the Techstream on. Enter the following menus: Body Electrical / Main Body / Active Test. Perform the Active Test according to the display on the Techstream.
