wo befindet sich der RSC Sensor?

[Mario.P]

Hab gestern ein Fehler ganz übersehen: c1280 yaw rate sensor fault. Das ist wohl das eigentliche Problem. Weiß jemand welcher Sensor das ist ?

[Driver]

YRS = Yaw Rate Sensor = Gierratensensor, wird bei ESP benötigt; (Drehratensensor), Bosch

ESP
Elektronisches Stabilitäts Programm

engl. Electronic Stability Programm
von Bosch, erkennt Schlupf in Längs- und Querrichtung (z.B. seitliches Wegrutschen in Kurven); Korrektur durch gezieltes Abbremsen von einzelnen Rädern; einzelne Systeme: ABS, ABV, ASR, GMR;

Hallo Tom

Wenn du mir jetzt noch sagen kannst wo sich genau der Sensor befindet dann bin ich glücklich . Irgendwo im innenraum stimmt das ?!

Dies ist die TSB dazu...?

08-14-2 • STABILITY/TRACTION CONTROL INDICATOR - SLIDING-CAR ICON - ON OR FLASHING - DTC C1996 OR SENSITIVE ESC/RSC ACTIVATION NO CODES
Publication Date: June 26, 2008

FORD: 2007-2008 Expedition
LINCOLN: 2007-2008 Navigator
ISSUE:
Some 2007-2008 Expedition and Navigator vehicles equipped with electronic stability control (ESC)/roll stability control (RSC) may exhibit the stability/traction control indicator "sliding-car icon" on or flashing with diagnostic trouble code (DTC) C1996 or sensitive ESC/RSC activation with no codes.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE EVALUATION PROCEDURE
Determine if this procedure applies by answering the following questions:
1. Was the customer pulling a trailer when the concern occurred?
1. No, go to question 2.
2. Yes, do not proceed with this procedure. Vehicles pulling heavy trailers have the possibility to have a sensitive activation or DTC C1996. This is a normal characteristic and no corrective action needed.
2. Was the stability/traction control indicator "sliding-car icon" on or flashing during the concern?
1. No, do not proceed with this procedure and refer to normal workshop manual diagnostics.
2. Yes, proceed to question 3.
3. Did the concern occur during acceleration?
1. Yes, proceed to question 4.
2. If no, go to question 5.
4. Test drive the vehicle on curves and/or bumpy roads. Monitor all four wheel speed sensors.
o Left Front Wheel Speed Sensor (LF_WSPD).
o Right Front Wheel Speed Sensor (RF_WSPD).
o Left Rear Wheel Speed Sensor (LR_WSPD).
o Right Rear Wheel Speed Sensor (RR_WSPD).
o Are the values similar, ± 6 MPH (10 Km/h)?
6. No, they vary, proceed to Diagnostic Service Procedure Step 5.
7. Yes, go to question 5.
5. Has this concern occurred more than once?
0. Yes, go to question 6.
1. No, go to Diagnostic Service Procedure Step 1.
6. Has the Stability Control Sensor Cluster been previously replaced?
0. Yes, go to Diagnostic Service Procedure Step 6.
1. No, go to question 7.
7. Did the activation occur in less than 2 minutes after starting and driving the vehicle?
0. Yes, go to Diagnostic Service Procedure Step 6.
1. If no, go to Diagnostic Service Procedure Step 1.
DIAGNOSTIC SERVICE PROCEDURE
1. Are after market accessories installed?
1. Yes, repair sources of vibration (sub-woofer, modified center console). Proceed to Step 2.
2. No, proceed to Step 2.
2. Steering wheel angle (SWA) sensor inspection.
1. Visually inspect the optical tone ring for contamination or debris.
1. Clean as necessary.
2. Inspect the SWA connector for looseness. Reconnect as necessary.
1. Push, click, and pull to verify a good connection.
3. Visually inspect around the area of the steering column/tone ring for signs of light entering the cabin, shining through the windshield between the defroster grill and instrument panel (IP). Defroster grill variation may allow for slight gaps, enough to leak light.
1. Use IP colored foam to block any gaps (tape not recommended as it may loosen and fall off).
2. If no problems found with the SWA system, proceed to Step 3.
3. Inspect mounting/torque of the bolts holding the stability control sensor cluster in position.
1. Look for looseness of bolts or distortion of the sheet metal.
2. Check the connector (pin push outs) and wiring (chafe) to the stability control sensor cluster.
3. If no problems found with the stability control sensor cluster proceed to Step 4.
4. Start engine and keep vehicle at a stand still. Monitor the YAW rate PID value for the Stability Control Sensor Cluster. Expected values: ± 2.0 d/s YAW.
1. If not within specification, replace the Stability Control Sensor Cluster per the Workshop Manual (WSM), Section 206-09: Vehicle Dynamic Systems.
2. If within specification, go to Step 5.
5. Refer to Symptom Chart in the WSM, Section 206-09: Vehicle Dynamic Systems: Unintended ABS activation, ABS too sensitive, ABS activates on a normal stop.
1. If no problem found with the base brakes or wheel speed sensors, proceed to Step 6.
6. If all steps above have no concern or are repaired and concern still exhibited, or you have been previosly directed to this step, replace the ABS module per the WSM, Section 206-09: Vehicle Dynamic Systems.

Hallo dani

Vielen dank für die Hilfe, wenn ich das richtig verstanden habe sitzt der Sensor in der Mittelkonsole. Schau heut gleich mal nach

[Mario.P]

Hallo Leute

Also in der Mittelkonsole ist der yaw rate Sensor definitiv nicht. Habe was neben dem Gaspedal gefunden, bin mir nur nicht ganz sicher ob das auch tatsächlich der gesuchte Sensor ist:

[Dani]

Stability Control Sensor Cluster, befindet sich unter dem Mittelteil der Instrumeneinheit

Stability control sensor cluster — located under the center portion of the instrument panel and contains several sensors (yaw rate, roll rate, lateral
accelerometer and longitudinal accelerometer).
