Diagnostic Trouble
Code Description
Repair Information
1
YRS Signal Out of
Range
The YRS signal is incorrect. Verify the proper installation of the YRS. Verify proper
wiring between the Electronic Control Unit (ECU) and the YRS. Check the YRS output.
Perform the YRS calibration procedure.
2
YRS Sensor
Reversed Signal
The YRS signal is reversed. Verify the proper installation of the YRS. Verify the wiring
between the ECU and the YRS. Check the YRS output.
3
YRS Invalid Signal
The YRS signal is invalid. Verify the proper installation of the YRS. Verify proper
wiring between the ECU and the YRS. Check the YRS output. Verify that correct
YRS is being used.
4
YRS Gradient Error
5
YRS CAN Time‑out Loss of CAN communications between the ECU and the YRS. Verify proper wiring
between the ECU and the YRS. Check the YRS output.
6
YRS Static BITE
Error
The YRS signal fails static self‑test. Verify the proper installation of the YRS. Verify
proper wiring between the ECU and the YRS. Check the YRS output. Verify that
correct YRS is being used. Verify proper ECU programming. Perform the YRS
calibration procedure.
7
YRS Dynamic BITE
Error
The YRS signal fails self‑test conducted while vehicle is in motion. Verify the proper
installation of the YRS. Verify proper wiring between the ECU and the YRS. Check the
YRS output. Verify that correct YRS is being used. Verify proper ECU programming.
Perform the YRS calibration procedure.
8
YRS Fast Calibration
Error
There is a YRS calibration error. Verify the proper installation of the YRS. Verify proper
wiring between the ECU and the YRS. Check the YRS output. Verify that correct YRS is
being used. Verify proper ECU programming. Perform the YRS calibration procedure..
9
YRS Static
Calibration Error
10
YRS Normal
Calibration Error
There is a YRS calibration error. Verify the proper installation of the YRS. Verify proper
wiring between the ECU and the YRS. Check the YRS output. Verify that correct YRS
is being used. Verify proper ECU programming. Perform the YRS calibration procedure.
12
YRS Plausibility
Check (Ref Yaw
Rate)
The ECU has detected an incorrect YRS signal. Verify the proper installation of the
YRS. Verify proper wiring between the ECU and the YRS. Check the YRS output.
Verify that correct YRS is being used. Verify proper ECU programming. Perform the
YRS calibration procedure.
13
YRS Plausibility Error
(Inside Model Based
Limits)
14
YRS Plausibility
Error (Outside Model
Based Limits)
15
YRS ‑ SAS Signal
Cross‑check
Incomplete
The ECU (if congured) must conrm that YRS and SAS signals match. The vehicle
must be exposed to an S‑shaped driving maneuver for this DTC to automatically clear.
If the DTC does not clear even after the S‑shaped driving maneuver, check and correct
the orientation of the YRS and then repeat the maneuver.
16
YRS ‑ Vibration
Detected
Inspect the YRS mounting and verify it is securely mounted. Note that the YRS may
not be relocated from the OEM‑installed position on vehicle without written Bendix
Engineering approval.
17
YRS Detected But
Not Congured
Verify that the ECU is congured for ESP.
