Techstream ECU Flash Reprogramming Procedure

Operation Procedure (Continued)

NOTICE

Errors during the flash reprogramming process can permanently damage the vehicle ECU.
Minimize the risk by following the steps below.

* Battery voltage MUST NOT FALL BELOW 11.4 volts during reprogramming. Confirm
battery voltage is higher than 11.4 volts, but be sure voltage DOES NOT RISE ABOVE
16.0 volts during reprogramming.

¢ Turn OFF alt vehicle accessories (e.g. audio system, A/C, interior lights, DRL, etc.). Do
NOT add to or significantly change the vehicle's electrical load while reprogramming.

. Confirm the hood is open and ensure under hood temperature does NOT exceed 158°F
(70°C).

* Confirm cable connections between the vehicle and Techstream are secure.

* Do NOT disconnect or turn off Techstream or vehicle ignition during reprogramming.
* Set parking brake.

» Complete ALL flash calibration updates provided for each ECU.

+ If the battery’s state of charge or capacity are in question, test with SST. No.
00002-V8150-KIT “Digital Battery Analyzer,’ and follow Service Bulletin No. PG001-06,
“Battery Maintenance for In-Stock Vehicles & Pre-Delivery”, or the appropriate
“Maintenance for HV & Auxiliary Batteries” Service Bulletin.

* The GR8 Battery Diagnostic Station MUST be used in Power Supply Mode to maintain
battery voltage at 13.5 volts while flash reprogramming the vehicle. For details on how to
use the GR8 Battery Diagnostic Station, refer to the GR8 Instruction Manual located on
TIS, Diagnostics - Tools & Equipment — Battery Diagnostics.
