Even though this is just one of the many Step-By-Step Procedures covered in the TECH2PATHS Document listed in my “GYMKO” Bench Top Test Harness Thread, having recently viewed THIS IPC Repair Video and observed the VOP (Video Original Poster) performing an
IPC “Sweep Test” numerous times on his
Bosch Vetronix Tech 2… I thought I’d post the specific Keypad Steps needed to get to it and make it work for our Tech 2 Owners:
How to Perform an Instrument Panel Cluster Sweep Test with a “GYMKO” Tech 2:
(1) Follow all correct Tech 2 Set Up Procedures, including ensuring that the Battery B+ Power is well above 12 Volts DC prior to performing this Test inside of the Vehicle.
(2) Connect the Tech 2 to the DLC and insert the Power Cord into the DLC Cable Port… NOT by using the Cigarette Lighter Feature and use the remote B+ and Ground cables attached directly to the Battery Terminals for the Tech 2 instead.
(3) Power Up the Tech 2 from the Keypad Button, Then Navigate to the Sweep Features by following THIS Touch Pattern:
BODY→INSTRUMENT PANEL CLUSTER → SPECIAL FUNCTIONS → IPC GAUGES →DISPLAY(S) TESTS
These Actions should reveal any of the Dash Panel IPC Gauges that are either
Sticking, are Stuck, or Completely Inoperative.
Please observe the Actions of the VOP as he Presses the Buttons of the Tech 2 Keypad during the latter portion of the above shown Video.
NOTE:
For any Owners of
2003-2005 Full Size Trucks and SUVs, the attached PDF covers a Warranty Extension
that has probably expired since THIS Document was published back in 2009 and later based upon the 06-10-2014 identification of this Document.
However in this instance, it serves to show us this very same procedure being instructed for dealership staff to follow and use just prior to the IPC being updated using the GM ACDelco TIS2WEB Features of the Tech 2 for re-calibration updating:

Please note that I’ve penned an extensive Thread on the subject of creating various Bench-Top Test Harnesses for use with the “GYMKO” Tech 2 that can be followed for creating your own since these are NOT readily available. Focus on the Information provided in
Post #42 for All of the Dope on The IPC Harness:
