Reversing, function - GF54.65-P-4001A

MODELS 140,163,168, 202, 208, 210, 215, 220 with CODE (220a) Parktronic System (PTS) 

Function requirements 

• Circuit 15 ON,
• Selector lever position in "R" or "N"(with code (420) automatic transmission, center shifter console),
• The lower speed limit is dropped below,
• No trailer operation (with code (550) trailer hitch),
• The Parktronic system (PTS) is not deactivated manually via the PTS ON/OFF switch (S95).

Detection of vehicle movement: 

Reversing is detected

in vehicles with manual transmission:

• via the backup lamp switch (S16/2),

in vehicles with automatic transmission:

• starter lock-out and back-up lamp switch (S16/1),
• starter lock-out and back-up lamp switch/detection of selector lever position (S16/3),
• gear recognition switch (S16/10).

The rear sensors and warning indicators are only active when reversing without trailer.

The front sensors and warning indicators are active irrespective of the trailer so that obstacles in the front swivel range of the vehicle are also detected when reversing.

When reversing with a trailer, the rear sensors and warning indicators are not active because otherwise the trailer would always be identified as an obstruction.

The trailer is detected by a trailer recognition microswitch (X58s1) in the power outlet for the trailer hitch with code (550) trailer hitch.

If an adapter (7/13 pin) is used for trailer operation, it must be removed after operating the trailer, because otherwise the system continues to detect a trailer and allows the rear sensors and warning indicators to be switched off.

Trailer recognition by the trailer recognition microswitch (X58s1) is not applicable on models 215 and 220 as of 1.5.99. Here the trailer is recognized by the trailer recognition control unit (N28/1). Trailer recognition is conveyed to the Parktronic control unit (<>) via the Controller Area Network bus class B (interior) (CAN-B) (N62).

Monitoring area (vehicle rear): 

Vehicle center: approx. 120 cm

Outside of vehicle: approx. 80 cm

An obstacle is no longer detected at a distance below approx. 20 cm.

The detection range is divided into a left-hand and a right-hand sector, each with two sensors and one visual warning display. The acoustic signal is combined for the two rear warning indicators.

Variant coding can be carried out for the Parktronic control unit (N62) using STAR DIAGNOSIS. On vehicles without a detachable trailer hitch (models 163, 168) or with a spare wheel on the vehicle rear (model 163), this makes possible an extension of the warning range of the sensors.

Variant coding makes it possible to adjust the warning range of the sensors to changes in the overall length of the vehicle.
