DI_a200 — Vdc Model Based Plausibility
Full alert identifier: DI_a200_vdcModelBasedPlausibility
Alert description
The drive interface (DI) electronic control unit (ECU) detects implausible input signals for traction and stability control.
Potential impact
Traction control and stability control may not be available, requiring greater manual input from the driver.
Set condition
The drive inverter detects implausible values from one or more inputs. Alert log signal data provides information on the specific signal(s) identified as implausible. Causes may include improper wheel alignment causing large steering angle offsets, incorrectly mounted restraint control module (RCM) causing RCM signals to be implausible, or intermittent wheel speed connections causing irrational signal values.
Clear condition
This alert will clear on the next drive cycle. It will continue to set sometime into the next drive cycle if the suspected signal is still providing implausible values. Drive vehicle for several miles after correcting the issue to ensure this alert does not return.
