If you are investigating a car that keeps bouncing after a bump, save every stored and pending code before clearing anything. Scan tools generally do not measure damper condition on ordinary cars. Record the engine temperature and load alongside the reading; the same value can mean different things in different conditions.
A basic reader may not access every module. Inspect tire wear and visible fluid on dampers; do not perform unsafe bouncing or lifting tests. Use the exact vehicle’s service information to interpret the result.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
