Flash: Powertrain Diagnostic and System Improvements
This bulletin involves reprogramming of the Powertrain Control Module (PCM) with the latest software.
Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find that the following DTCs: P000B - Bank 1 Camshaft 2 Position Slow Response.
P0016 - Crankshaft/Camshaft Timing Misalignment - Bank 1 Sensor 1.
P0335 - Crankshaft Position Sensor Circuit.
P0339 - Crankshaft Position Sensor Intermittent.
P0441 - EVAP Purge System Performance.
P0455 - EVAP System Large Leak.
P2610 - PCM Internal Engine Off Timer Performance.
P0456 - EVAP System Small Leak.
P2299 - Brake Pedal Position/Accelerator Pedal Position Incompatible.
Customers may also notice the following condition(s): Brief engine idle fluctuation while in hot ambient temperatures.
A slight hesitation during light pedal application after engine cold start.
Driveline noises.
Engine stumble/hesitation on a very hard pedal acceleration from a dead stop.
Transmission enhancements during low-speed braking turning maneuvers.
False detonation (spark knock) detected during a wide-open throttle (LA Challenger Sales Codes ESH with DEC only).
In addition, the following software enhancements are available: Reduce bumps felt on light to medium decal braking and coming to a stop.
Launch spark improvement change from 35 MPH to 10 MPH.
Reverse lock out speed change from 10 MPH to 3 MPH (Sales Code DEC only).
Torque security calibration changes to desensitize brake throttle override entry conditions.
Calibration changes to address engine speed undershoot/overshoot during clutch disengagement when coming to a stop (Sales Code
DEC only).
Start fuel and transient fuel calibration change for improved drivability robustness.
Purge calibration changes for a more robust purge volume result at altitude.
Individual Cylinder Fuel Control (ICFC) calibration changes for improved fueling offset accuracy.
