TAS_a164 — Damper Solenoid Mismatch

Full alert identifier: TAS_a164_damperSolenoidMismatch

Alert description

The damper valve solenoid type configuration value reported by the vehicle gateway (GTW) does not match the damper valve solenoid type supported by the firmware version running on the Tesla Air Suspension (TAS) electronic control unit (ECU).

Potential impact

Adaptive damping controls are unavailable. All dampers receive a fixed mid-level current instead.

Set condition

The TAS ECU detects a mismatch between the damper valve solenoid type supported by its firmware and the damper valve solenoid type reported by the GTW.

Clear condition

The damper valve solenoid type reported by the GTW matches the damper valve solenoid type supported by the TAS ECU firmware.
