YRS Signal Out of
Range
YRS signal incorrect. Verify proper installation of the YRS. Verify proper wiring between
the ECU and the YRS. Check YRS output. Perform YRS calibration procedure.
2
YRS Sensor
Reversed Signal
YRS signal is reversed. Verify proper installation of the YRS. Verify proper wiring
between the ECU and the YRS. Check YRS output.
3
YRS Invalid Signal
YRS signal is invalid. Verify proper installation of the YRS. Verify proper wiring between
the ECU and the YRS. Check YRS output. Verify that correct YRS is being used.
4

the ECU and the YRS. Check YRS output. Verify that correct YRS is being used.
5
YRS CAN Timeout
Loss of CAN communications between the ECU and the YRS. Verify proper wiring
between the ECU and the YRS. Check YRS output.
6
YRS Static BITE
Error
YRS signal fails static self-test. Verify proper installation of the YRS. Verify proper
wiring between the ECU and the YRS. Check YRS output. Verify that correct YRS
is being used. Verify proper ECU programming. Perform YRS calibration procedure.
7
YRS Dynamic BITE
Error
YRS signal fails self-test conducted while vehicle is in motion. Verify proper installation
of the YRS. Verify proper wiring between the ECU and the YRS. Check YRS output.
Verify that correct YRS is being used. Verify proper ECU programming. Perform YRS
calibration procedure.
8
YRS Fast Calibration
Error

the ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify
proper ECU programming. Perform YRS calibration procedure.
9
YRS Static
Calibration Error
YRS calibration error. Verify proper installation of the YRS. Verify proper wiring between
the ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify
proper ECU programming. Perform YRS calibration procedure.
10
YRS Normal
Calibration Error
YRS calibration error. Verify proper installation of the YRS. Verify proper wiring between
the ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify
proper ECU programming. Perform YRS calibration procedure.
11
YRS Sensitivity
Calibration Error
YRS calibration error. Verify proper installation of the YRS. Verify proper wiring between
the ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify
proper ECU programming. Perform YRS calibration procedure.
12
YRS Plausibility
Check (Ref Yaw
Rate)
ECU has detected an incorrect YRS signal. Verify proper installation of the YRS. Verify
proper wiring between the ECU and the YRS. Check YRS output. Verify that correct YRS
is being used. Verify proper ECU programming. Perform YRS calibration procedure.
13
YRS Plausibility Error
(Inside Model Based
Limits)
ECU has detected an incorrect YRS signal. Verify proper installation of the YRS. Verify
proper wiring between the ECU and the YRS. Check YRS output. Verify that correct YRS
is being used. Verify proper ECU programming. Perform YRS calibration procedure.
14
YRS Plausibility
Error (Outside Model
Based Limits)
ECU has detected an incorrect YRS signal. Verify proper installation of the YRS. Verify
proper wiring between the ECU and the YRS. Check YRS output. Verify that correct YRS
is being used. Verify proper ECU programming. Perform YRS calibration procedure.
15
YRS - SAS Signal
Cross-check
Incomplete
ECU (if configured) must confirm 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 repeat maneuver.
16
YRS - Vibration
Detected
Inspect YRS mounting and verify it is securely mounted. Note that YRS may not be
relocated from OEM-installed position on vehicle without written Bendix Engineering
approval.
