01487 - System Function Test
01487 - System Function Test
Possible Symptoms
- Malfunction Indicator Light (MIL) ON
Possible Causes
- When found in Brake Electronics Control Module (J104)
- Brake Electronics Function Test Timed Out
Possible Solutions
- When found in Brake Electronics Control Module (J104)
- Perform Brake Electronics Function Test
Special Notes
- When found in Brake Electronics Control Module (J104)

01487 - System Function Test: Implausible Signal
Possible Symptoms
- Malfunction Indicator Light (MIL) ON
Possible Causes
- When found in Control Module for Level Control (J197)
- Internal Error in Control Module for Level Control (J197)
- Control Module for Level Control (J197) faulty
Special Notes
- When found in Audi A8 (4E) or Bentley Continental (3W): Level Control (J197), this Fault Code can have several different Causes but by clearing Fault Codes most of those will be reset. Switch OFF the Ignition for 5 Seconds and then switch it back ON again, now clear Fault Codes and re-check for Fault Codes. If no Fault Code remains you are done. If the fault code remains, switch OFF the Ignition for 5 Seconds again and then switch it back ON. Now wait 5 Minutes before re-checking for Fault Codes! If after these 5 Minutes the Fault Code remains you may need to replace the Control Module for Level Control (J197).
