Design Limitations
Registration Security Warning
Vehicle: N/A
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Techstreams with Internet Explorer
version 8 will encounter a Security Warning pop-up
during the Software Registration process.
Work Around: Click "No" to proceed normally, clicking
"Yes" will take longer to complete.
DTC P1121 description misleading
Vehicle: 2004-2009 Toyota Prius
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Due to the Prius now sharing an ECU with
5LE equipped vehicles, the DTC now reads,
"Throttle/Pedal Position Sensor/Coolant Valve Position
Sensor Circuit Stuck", whereas it previously read,
"Coolant Flow Control Valve Position Sensor Circuit
Stuck".
Work Around: Refer to the TIS Repair Manual for the
relevant portion of the DTC.
Monitor for O2 sensor fails consistently
Vehicle:
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Monitor for O2 sensor consistently fails resulting in
a “complete/incomplete failâ€. This is a result of an ECU bug� inherent to this vehicle (410-041). In most cases, the O2 Sensors are functioning properly even if a “complete/incomplete fail†result� is seen. Verify O2 sensor operation by other processes to determine if further diagnosis is required.
Confusing PIDs Displayed in TPMS ECU
Vehicle: Vehicles NOT equipped with a factory optional
5th TPMS sensor, i.e. some 2013 RAV4s and 2014
Highlanders.
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: PIDs indicating the presence of a 5th
TPMS sensor are displayed in the Data List and Health
Check results on vehicles allegedly not equipped with a
5th sensor. These vehicles may come equipped with an
optional 5th sensor, and this can be physically verified
by inspecting the spare tire.
Monitor Function Unavailable
Vehicle: 2013 FR-S
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIM)
Description: Function not available for this vehicle.
The button is grayed out (810-007).
Powertrain DTCs with FFD Have No Designation
Vehicle: All
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: When viewing Trouble Codes or saved
Health Check data, Powertrain DTCs with FFD may have
no designation as to what type of FFD is saved.
Confusing Door Courtesy Light Values
Vehicle: 2008-2011 Sienna
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Parameters “FR and FL Door
Courtesy†in the Main Body ECU Datalist will display�
an “ON†value when those doors are closed.�
Siennas with a L/O date of November 2011 (2012MY)
and forward will display values logically; consistent
with the rear doors.
Fatal Errors with Tire Pressure Monitor System
Vehicle: 2012 Camry, 2013 GS350, and possibly other
vehicles
Device(s): Techstream Lite (Mongoose VIM)
Description: When using Techstream Lite with
firmware version v01.02.06 or lower, viewing the
Datalist and using other functions in the Tire Pressure
Monitor System ECU will cause fatal errors.
Work Around: If you are using firmware v01.02.06 or
lower, upgrade your firmware to v01.02.07 (choose
either 32-bit or 64-bit OS, depending on your specs) or
use Full Techstream.
Cannot Connect Using Generic OBDII
Vehicle: All, including other makes/brands of vehicle
Device(s): Techstream Lite (Mongoose and/or
Mongoose Pro VIMs)
Description: When using a Mongoose VIM to connect
Techstream to a vehicle via Generic OBDII, the result is
an error window that displays "Cannot establish
communication with the ECU."
HL AutoLeveling Active Test Inapplicability and Errors
Vehicle: 2010 Prius
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Due to an ECU bug, inapplicable Active
Tests may display. Furthermore, the Drive Leveling
Motor Active Tests may fail to execute, resulting in an
error.
EVAP System Check Failure
Vehicle: 2006 LS430
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Attempting to perform EVAP System
Check will result in error screen and the function will be
inoperable. Please refer to the repair manual for
instructions on manually inspecting the Evap System.
Single and Multi Freeze Frame Data Display is Erratic
Vehicle(s): All
Device(s): Techstream and Techstream Lite (Mongoose
and/or Mongoose Pro VIMs)
Description: Given the same DTC and same
year/make/model vehicle, FFD display can be very
erratic, sometimes displayed as Single Frame and
sometimes as Multi Frame.
Status: Under investigation. If you encounter this
issue, please press the F12 key to create an Error
Report.
Health Check DTC Clear All Failure
Vehicle: 2009-2010 Corolla, xD
Device(s): Techstream and Techstream Lite (Mongoose
VIM)
Description: When using the Clear All DTC function
from the Health Check Screen, with IG ON and engine
not running, the progress indicator will loop
continuously until the DTCs clear (after 5 or 6 minutes).
This also occurs when clearing DTCs of the EMPS
System. This issue can be avoided by having the
engine running while clearing DTCs.
Unable to Perform VIN Write Unless Exiting the
Application
Vehicle: 04MY Vehicles reprogrammed with a 05MY
Calibration
Device(s): Techstream and Techstream Lite (Mongoose
VIM)
Description: Unable to perform VIN Write on a 04MY
Vehicle, after reprogramming the Engine and ECT ECU
with a 05MY Calibration file. Since it is very difficult for
the software to identify a 04 Vehicle after updating with
a '05 Calibration file, you must exit out of the
application and reconnect to utilize the VIN write
function.
Immobilizer/Smart Key Reset Abnormal Operation
Vehicle: All
Device(s): Techstream and Techstream Lite (Mongoose
VIM)
Description: When performing an Immobilizer or
Smart Key Reset, errors or abnormal operation may
occur if Java software is not installed, has become
corrupt, or version is too old. Installing the latest
version of Java (v1.6 - Update 7, minimum) from
http://www.java.com will resolve this issue.
Vibration or Movement Causes Comm Errors
Vehicle(s): All
Device(s): Techstream (when using the VIM via USB -
no backpack) and Techstream Lite (Mongoose and/or
Mongoose Pro VIMs)
Description: Certain laptops with HDD vibration
protection software experience intermittent
communication loss when the laptop is jerked or
moved, which forces the user to restart Techstream.
Status: Issue is under investigation.
Work Around: Though each PC is different, at your
own risk, the HDD vibration protection software may be
adjusted to be less sensitive, which may increase the
risk of HDD damage during abrupt movement or if the
PC is dropped.
