SUBJECT:
Flash: DTC P21101 Electronic Throttle Control (ETC) Lamp Flashes at Speeds Greater Than 95 Miles Per Hour
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM).
NOTE:
Vehicles equipped with a CVT transmission must have the transmission control module (TCM) checked for the latest software level whenever the
PCM software is updated. If newer TCM software is available, it must be installed. Failure to maintain software coordination may result in MIL
illumination or driveability concerns.
MODELS:
**2007** - 2008
(MK74)
Patriot
NOTE:
This Bulletin applies to models equipped with a 2.4L engine & automatic CVT2L (Off Road) transmission (Sales Code ED3 with DAW) built prior
to April 2, 2008 (MDH 0402XX).
SYMPTOM/CONDITION:
Some customers may experience the electronic throttle control (ETC) lamp flashing in the instrument panel if the vehicle is driven over 95 miles per
hour. Vehicles equipped with a CVT2L (Off Road) transmission are not designed to be driven at excess speeds. To protect the transmission, vehicle
systems will "torque limit at speeds greater than 95 miles per hour and will prevent the vehicle from going faster. The ETC lamp flashing may cause
customer concern, especially when the vehicle torque limits and prevents the vehicle from going faster.
NOTE:
It is normal for vehicles equipped with a CVT2L transmission to torque limit and prevent vehicle speeds above 95 MPH.
Further investigation by the technician may find DTC 2110 - Electronic Throttle Control - Forced Limited RPM.
It is important that the customer understands the operating characteristics of the vehicle. The software available with this Service Bulletin will eliminate
ETC lamp flashing but will not change the torque limits associated with vehicle operation.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as
designed. If DTC's other than P2110 are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the above symptom/condition is experienced and the operating characteristics of the vehicle have been explained to the customer along with the
expectations of this flash update, perform the Repair Procedure.
