SUBJECT:
ENGINE CONTROL MODULE REPROGRAMMING FOR POOR HEATER PERFORMANCE
This TSB supercedes TSB-08-55-002, issued February, 2008, for revised information relating to vehicle specifications plus other clarifications. Revised
information is indicated by <.
PURPOSE
To improve heater performance during extremely cold weather, (at or below approximately +5°F, -15°C), a new software program is being made
available for those affected vehicles where there has been a complaint of insufficient heating of the interior. The condition is mostly noticed when the
vehicle is stationary with the engine at idle or travelling at very slow speeds (e.g. stop and go traffic).
This Technical Service Bulletin advises the steps to reprogram the ECM with new parameters which will allow the engine idle to be increased when
temperatures are below approximately +5°F (-15°C).
