Error (Outside ECU
–specific Limits)
ECU has detected an incorrect LAS signal. Verify 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 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.).
