Cold Mopar

2011-2012 Dodge Caliber vehicles equipped with a 2.0L engine may experience long crank times when temperatures are between 0 and 50 degrees Fahrenheit after an eight-hour soak time. In order to correct this condition, PCM calibration has been changed to add cranking spark and reduce the start fueling.

Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, verify that all engine systems are functioning as designed. If DTCs are present, record and correct before proceeding further.

Install a battery charger to ensure that battery voltage does not drop below 13.2 volts or rise above 13.5 volts during the flash process.

Reprogram the PCM with the latest software Follow the procedures available in DealerCONNECT/TechCONNECT. Refer to Group 8 – Electrical > Electronic Control Modules – Service Information > Module – Powertrain Control > Standard Procedures > PCM/ECM Programming.

After reprogramming, clear any DTCs that may have set in other modules. Type the necessary information on an authorized modifications label and attach it near the VECI label.
