In November of 2006, ABS control module fault messages were detected a routine yard
audit of 2007 model year product at DCC's Belvidere Assembly Plant.
Affected vehicles were equipped with the Continental Teves Mark 25E ABS electronic
DEFECT INFORMATION REPORT FOR DAIMLERCHRYSLER RECALL F50
control unit (ECU) and electronic stability program (ESP).
On November 17, 2006, a yard hold was implemented for all corporate vehicles equipped
with the Mark 25E ECU and ABS/ESP.
Investigation determined the Mark 25E ECU flash loader software was incompatible with the
full manufactured specification range of a processing chip used in the ECU. If this
incompatibility were to occur, a loss of communication with the ECU would take place,
followed by warning lamp illumination and a loss of electronic brake distribution, traction
control, ABS and speedometer function.
Analysis of processing chip data showed a shift in data beginning in September of 2006 that
could result in this incompatibility for a small number of ECUs.
Revised ECU flash loader software was developed and validated to eliminate the potential
for this condition in late November of 2006. A reprogramming of all held vehicles was
In early December of 2006, a 2007 model year Chrysler Sebring without ESP at DCC's
Sterling Heights Assembly Plant was observed with similar warning lamp illumination and
stored faults for loss of communication. The ECU was returned to Continental Teves for
Continental Teves duplicated the loss of communication failure mode in cold chamber
testing and confirmed that Sebring vehicles equipped with ABS were also suspect for
incompatibility with the full manufactured specification range of the processing chip.
On December 12, 2006, a yard hold was implemented for 2007 Sebring ABS equipped
vehicles with Continental Teves Mark 25E ECU.
Revised ECU flash loader software was developed and validated to eliminate the poten.tial
for this condition and a reprogramming of all held vehicles was initiated.
There are no reports of accidents, injuries or property damage related to this condition.
This data was presented on December 19, 2006 to the Vehicle Regulations Committee who
decided to conduct a safety recall to reprogram the ABS control module software on the
affected vehicle population.
Statement of measures to be taken to correct defect:
DCC will reprogram the ABS electronic control unit on the affected vehicle population with new
software that prevents this condition. Due to the need for certain specific braking conditions to
induce the wheel lock condition and the lack of any known accidents, injuries, or property damage,
DCC has concluded that the three day dealer notification rule does not apply. DCC expects to
initiate national notification to both dealers and to owners in February of 2007.
