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).
AFFECTED VEHICLES <
REQUIRED OPERATIONS
The following equipment is needed to reprogram the ECM.
^ VCI (Vehicle Communication Interface) - MB991824
^ Laptop computer with A/C power adaptor - 520924, 528535, or 547708
^ MUT-III main harness 'A' (blue connector at the DLC end) - MB991910
^ USB 2.0 cable - MB991827

^ MEDIC-II Download at M210 or higher.
If an affected vehicle has a Service Engine Soon (SES) lamp illuminated and DTCs listed in the ECM memory (before reprogramming), follow diagnostic instructions for the applicable DTCs per the service manual information. Do not reprogram the ECM until the reason for DTCs being set is corrected.
IMPORTANT!!!
PRIOR TO BEGINNING REPROGRAMMING, ENSURE THAT THE TRANSMISSION CONTROL MODULE (TCM) IS AT THE LATEST REPROGRAMMING LEVEL. REFER TO THE TCM REPROGRAMMING INFORMATION THAT FOLLOWS.
IF THE TCM IS NOT TO THE LATEST REPROGRAMMING LEVEL, FOLLOW THE INSTRUCTIONS IN THIS TSB TO REPROGRAM THE ECM, THEN REFER TO TSB-07-23-006 TO REPROGRAM THE TCM. WHEN APPLICABLE ALWAYS REPROGRAM THE ECM PRIOR TO REPROGRAMMING THE TCM.
Determining Current TCM Programming Level
From the main menu, click System Select, and ensure "From 2006MY" is selected at the right side of the screen. Click the car icon and input the correct VIN for your vehicle.
