A flashing Drive (D) indicator light on a Honda CR-V’s instrument panel signals a potential problem within the vehicle’s transmission system. This visual alert serves as a crucial diagnostic tool, often accompanied by noticeable changes in driving performance such as rough shifting, delayed engagement, or slippage. A flashing indicator differs from a consistently illuminated one, which can sometimes simply indicate the gear selector’s position. The flashing light specifically signifies a detected fault.
Prompt attention to this warning is vital for preventing further damage to the transmission. Ignoring the signal can lead to costly repairs or even complete transmission failure. Historically, vehicle diagnostics relied on less sophisticated methods. The evolution of onboard computer systems and indicator lights allows for early detection of potential issues, empowering drivers to address them proactively. This contributes to increased vehicle longevity and safety.
