SYMPTOM/CONDITION:
A small number of customers may experience one or more of the following symptoms
and/or a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the
technician may find one or more of the following Diagnostic Trouble Codes (DTCs):
•
•
P1217 - Active Exhaust Valve 1 Performance.
P121B - Active Exhaust Valve 2 Performance.
In addition, customers may also comment on the following:
•
•
Unable to accurately increase or decrease the cruise control set speed using the
resume or set buttons while the instrument cluster is set on metric units. Instead of
changing vehicle speed by 1 KPH when pressing the buttons, the vehicle speed will
increase approximately 1.6 KPH.
Slight spark knock condition during aggressive high speed driving which may
prevent the vehicle from achieving maximum top speed.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTCs or
symptom conditions, other than the ones listed above are present, record the issues on the
repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above or if the technician finds the
DTCs, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the PCM with the latest software. Detailed instructions for flashing control
modules using the wiTECH Diagnostic Application are available by selecting the
application’s “HELP” tab.
2. Clear all DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow them
to be cleared.
