Subaru Outback ABS, traction control, and parking brake lights on with ER 55, suspected ABS motor issue after brake job on Subaru Outback

Some Subaru Outback owners report experiencing issues indicated by the ABS, traction control, and parking brake lights being illuminated alongside the ER 55 code, which may suggest a malfunction in the ABS system, particularly the ABS motor, after a brake job. These owners note that the ABS light signifies a failure in the self-diagnostic cycle, pointing to potential problems within the Anti-Lock braking system. Additionally, they mention that the warning lights can be triggered by factors such as temporary traction loss, faulty sensors, ABS malfunctions, or broken modules. Inaccurate information from wheel hub sensors can also lead to the ABS light activation. Furthermore, some owners have reported the traction control light being on along with other warning indicators, necessitating diagnostic testing to uncover issues like a faulty valve body or sensor. It is recommended that affected owners have their vehicles inspected by a qualified mechanic for proper diagnosis and resolution of these issues.
