remote jump posts under the hood (if equipped).
3. VERIFY TECHSTREAM SETUP
a. Verify that the Techstream meets the following conditions:
• The latest version of software is loaded.
• The Techstream battery is fully charged. If not, connect the Techstream to a 120v
source.
• The DLCIII cable is in good condition.
The Techstream’s battery voltage must be maintained during the
update procedure. If necessary, plug the Techstream into a 120v
outlet during this procedure.
Note: If the Techstream’s communication with the vehicle fails during the update
procedure, the Engine ECU will be damaged.
