Repair Information
1
LAS Signal Out of
Range
LAS signal incorrect. Verify the proper installation of the YRS/LAS. Verify
proper wiring between the Electronic Control Unit (ECU) and the YRS/LAS.
Check YRS/LAS output. Perform LAS calibration procedure.
2 LAS Calibration in
Progress
LAS calibration procedure is underway.
3 LAS Static
Calibration Error
LAS calibration error. Verify the proper installation of the YRS/LAS. Verify
proper wiring between the ECU and the YRS/LAS. Check YRS/LAS output.
Verify that correct YRS/LAS is being used. Verify proper ECU programming.
Perform LAS calibration procedure.
4 LAS Long Term
Calibration Error
LAS calibration error. Verify the proper installation of the YRS/LAS. Verify
proper wiring between the ECU and the YRS/LAS. Check YRS/LAS output.
Verify that correct YRS/LAS is being used. Verify proper ECU programming.
Perform LAS calibration procedure.
5 LAS Plausibility
Error (Inside ECU‑
specic Limits)
ECU has detected an incorrect LAS signal. Verify the proper installation of the
YRS/LAS. Verify proper wiring between the ECU and the YRS/LAS. Check
YRS/LAS output. Verify that correct YRS/LAS is being used. Verify proper
ECU programming. Perform LAS calibration procedure.
6 LAS Plausibility
Error (Outside ECU
–specic Limits)
ECU has detected an incorrect LAS signal. Verify the proper installation of the
YRS/LAS. Verify proper wiring between the ECU and the YRS/LAS. Check
YRS/LAS output. Verify that correct YRS/LAS is being used. Verify proper
ECU programming. Perform LAS calibration procedure.
7 Erratic ESP Sensor
Signal
ECU has detected an erratic signal. Verify the proper installation of the YRS/
LAS. Verify proper wiring between the ECU and the YRS/LAS. Check YRS/
LAS output. Verify that correct YRS/LAS is being used. Verify proper ECU
programming. Perform LAS calibration procedure.
(Note: When checking for voltage at YRS/LAS & SAS, the voltage will only be present momentarily at key ON.).
