This is a manufacturer-specific code. Its exact meaning can differ between makes; the definition below follows the most common usage.

What it means

B2152 is stored when the Seat Rear Vertical Motor Position Out of Range signal is electrically valid but does not make sense compared with other sensors or the expected operating range. The circuit is usually fine; the component or what it measures is out of specification.

This entry is compiled automatically from the standard definition and typical diagnostic practice for this type of fault. A detailed, reviewed article is in preparation.

Symptoms

  • The affected function (lighting, locking, windows, seats, climate or restraint) does not work or works intermittently
  • Warning light or message on the instrument cluster
  • Possible battery drain if a module stays awake

Common causes

  1. Seat Rear Vertical Motor Position Out of Range worn, contaminated or out of calibration
  2. Mechanical problem in the system the sensor measures
  3. Air, vacuum or exhaust leak influencing the reading
  4. Wrong or low-quality replacement part
  5. Wiring resistance causing a small voltage offset

How to diagnose

  1. Compare the live Seat Rear Vertical Motor Position Out of Range reading with a known-good value or a second sensor at idle and at 2500 rpm
  2. Check for air, vacuum or exhaust leaks that could skew the reading
  3. Inspect the component for contamination and clean it if the design allows
  4. Verify the part number is correct for the engine
  5. Replace the Seat Rear Vertical Motor Position Out of Range if the reading remains out of specification

Frequently asked questions

Can I keep driving with B2152?

Yes. The fault does not affect safety or driveability, but it will keep the warning light on and may fail an inspection.

Will clearing B2152 fix it?

No. Clearing only erases the stored code; it returns as soon as the monitor runs again unless the cause is repaired.
