AR46.10-P-0300-01I Activate steering angle sensor - 203 - 209 up to 31.5.04 - 215 - 220 - 230 up to 14.1.04 - 463.246 up to 30.5.04 - 463.249 up to 30.5.04 If the battery was disconnected or the voltage supply to the steering angle sensor was interrupted, the E and BAS control unit (with model 203, 209 and 463) or the ESP, SPS [PML] and BAS control unit (with model 215, 220 and 230) switches to malfunction mode. The message "EL. STAB. PROGRAM GO TO GARAGE" appears on the multifunction display. The steering-angle sensor must be re-activated to clear the malfunction.

ABS/ESP Indicator Lamp Illuminated / Fault Code C1140 and/or C1540 If you receive customer reports in the above model vehicles that the ABS/ESP indicator lamp is illuminated with fault code C1140 and/or C1504 (steering angle sensor not initialized), perform the below steps to resolve. Under no circumstance should the steering angle sensor or ESP control unit be replaced in an attempt to address this condition. Note: These fault codes may be the result of temporary voltage dips after start-up. Since the steering angle sensor is extremely sensitive to voltage changes, it is absolutely essential to use an oscilloscope (STAR Diagnosis system) with the smallest possible time graduation to collect data at a high frequency in order to obtain the most accurate measurement. 1. Check the on-board power supply voltage at the steering angle sensor during vehicle start-up. 2. Inspect the steering angle sensor connectors and harness for any loose contact and/or corrosion and correct as necessary.
