What does it mean?
B2335 is a Body (airbags, seat belts, body electronics) fault code. It indicates: Column Tilt Feedback Potentiometer Circuit Short to Ground .
Symptoms
- The column will not tilt upward, or moves only one way and strains against the stop.
- Memory recall no longer sets the tilt angle although the telescopic reach may still work.
- The tilt position value in live data stays at the bottom of the scale however the column moves.
- Easy entry and exit movement and storing new column memory positions no longer work.
- The fault often follows a spill into the column or work behind the column shrouds.
Likely causes
- Signal wire rubbed through against the column bracket, a metal edge or a fastener under the dash.
- Spilled drink running down the column and creating a path from the signal pin to ground.
- Terminal pushed back in the connector so it contacts the housing or an adjacent ground pin.
- Internal short between the tilt potentiometer track and the actuator body.
- Loss of the five volt reference from the column module, which the module can log the same way.
- Wiring crushed by the tilt mechanism or refitted incorrectly after column shroud removal.
- Column control module input stage failure.
How to fix it
- Check the tilt position value in live data; a value locked at or near zero while the column moves confirms a short to ground.
- Measure the five volt reference at the potentiometer connector first, since losing it produces the same reading.
- With the potentiometer unplugged, measure resistance between the feedback wire and ground on the harness side; a very low value proves the short.
- If the harness measures clean, check the potentiometer through its travel for a shorted or heavily worn track.
- Inspect the column loom at the tilt pivot and along the lower dash for chafing, crushing and trapped sections.
- Repair the wiring with sealed crimped joints, replace corroded terminals and dry out any spilled liquid.
- Replace the tilt potentiometer or actuator assembly once it is proven faulty, then relearn the column memory positions.
