This bulletin applies to 2012 Chrysler Grand Voyager models equipped with a 3.6L engine and built before June 25, 2012. The MIL may be on and DTC P0108 (manifold absolute pressure sensor circuit high) may be stored. This bulletin involves selectively erasing and reprogramming the PCM with new software.

Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, first verify that all engine systems are functioning as designed. If DTCs other than the one listed here are present, record and repair as needed before proceeding with the update.

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.

1. Reprogram the PCM with the latest software. In DealerCONNECT/TechCONNECT, refer to Group 8 – Electrical > Electronic Control Modules – Service Information > Module – Powertrain Control > Standard Procedures > PCM/ECM Programming.

2, After PCM reprogramming, clear any DTCs that may have set in other modules.

3. Type the necessary information on an authorized modification label and attach it near the VECI label.
