C1170 Code - Steering Angle Sensor Zero Point Variation
Quick Answer
The Electronic Stability Program (ESP) is an active safety system which improves vehicle stability in all driving situations. Common causes include Re-Initialize Steering Angle Sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1170 Description
It operates by actuating the brakes individually on one or more wheels on the front or rear axle. ESP stabilizes the vehicle when cornering, when braking or when coasting without power and holds it reliably in track.
ESP complements the familiar functions of the anti-lock brake system (ABS), acceleration slip regulation (ASR) and engine braking regulation (EBR).
The stability regulation function is superordinate to the ABS and ASR control systems. As well as actively intervening with the brakes, ESP also has an influence on engine/transmission management.
The Electronic Stability Program (ESP) includes the following system interplay:
ABS prevents the wheels from locking up during braking and thus maintains the steerability and directional control of the vehicle during deceleration.
ASR prevents the drive wheels from spinning while driving. It also improves directional control with better traction across the entire speed range.
EBR reduces brake slip at the drive wheels during deceleration and ensures directional control.
ESP prevents the vehicle from breaking away when it is oversteered or understeered. In all situations, it ensures that the vehicle does not deviate from the course specified by the driver (within the bounds of physical limits). Brake forces are produced selectively at the individual wheels to correct this.
