PT Cruiser L4-2.4L (2008)
-
Park Brake Reminder - The CCN will generate one short chime to announce that the hard wired input from the park brake switch and a vehicle
speed message input received over the CAN data bus indicate that the park brake is applied and the vehicle is moving. This chime will repeat each
time the input conditions are met.
-
Sentry Key "Customer Learn" Mode Announcement - The CCN will generate one short chime to confirm that an electronic "Customer Learn"
mode message has been received over the CAN data bus to indicate that the Sentry Key Remote Entry Module (SKREEM) is prepared for
programming additional sentry key transponders. This chime feature is only active on vehicles equipped with the optional Sentry Key system, and
sold in a market where "Customer Learn" programming is an allowed feature.
-
Turn Signal/Hazard Warning Flasher Emulation - The CCN relay will generate repetitive clicks at a slow rate to emulate an electromechanical
flasher when the turn signal or hazard warning system are operating. The CCN relay will generate repetitive clicks at a fast rate to indicate that the
right or left turn signal are operating with one or more bulbs inoperative. In either case, the clicks will continue until the turn signal and hazard
warning systems are turned off.
-
Turn Signal On Warning - The CCN will generate repetitive chimes at a slow rate to indicate that a turn signal has been active continuously for
1.6 kilometers (1 mile) with the vehicle speed greater than 22 kilometers-per-hour (15 miles-per hour). Vehicles built for markets other than the
United States and Canada have a revised distance threshold of 4 kilometers for this feature. The chime will continue until the turn signal input
becomes inactive or until the vehicle speed message indicates that the speed is less than 22 kilometers-per-hour (15 miles-per-hour), whichever
occurs first. The hazard warning flashers will not activate this chime feature.
-
Warning Indicator Announcement - The CCN will generate one short chime each time the Malfunction Indicator or MIL lamp is illuminated by
the instrument cluster circuitry. The check gauges indicator may be illuminated when any critical engine or transmission systems are operating
outside of their normal parameters. The instrument cluster monitors electronic messages received over the CAN data bus to determine when to
illuminate the check gauges indicator.
The CCN provides chime service for all available features in the chime warning system. The CCN relies upon its internal programming, numerous hard
wired inputs, and electronic message inputs received from other modules over the CAN data bus network to provide the chime warning system features.
The internal programming of the CCN determines the priority of each chime request input that is received, as well as the rate and duration of each chime
that is to be generated.
The hard wired chime warning system inputs to the CCN may be diagnosed and tested using conventional diagnostic tools and procedures. However,
conventional diagnostic methods may not prove conclusive in the diagnosis of the CCN, the CAN data bus, or the electronic messages received by the
CCN from other modules. The most reliable, efficient and accurate means to diagnose the CCN, the CAN/LIN data bus, or the electronic message inputs
used for the chime warning system requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
