What does it mean?
B2368 is a Body (airbags, seat belts, body electronics) fault code. It indicates: Window Washer Motor 1 Control Circuit Low .
Symptoms
- Indicator, wiper, headlamp or cruise control functions from the stalks work erratically or not at all
- The wrong function operates, for example wipers running when the lighting stalk is moved
- Stalk functions cut out over bumps or when the steering wheel is turned
- Some stalk positions work perfectly while others are completely dead
- A warning lamp on the cluster for whichever system the stalk controls
Likely causes
- Worn or contaminated contacts inside the multifunction column switch, giving a value between two defined steps
- Damaged clockspring or column loom after steering wheel, airbag or column work
- High resistance in the column connector caused by fretting corrosion
- Water running down the column from a leaking windscreen seal or a soaked footwell
- Signal wire partly shorted to another circuit in the same loom, shifting the measured value
- Incorrect or non matching column switch fitted during a previous repair
- Faulty reference or input stage inside the body control module
How to fix it
- Identify from the freeze frame and the manufacturer data which stalk function the module is complaining about
- Watch the column switch value in live data while stepping each stalk through every position and note where the value leaves its range
- Unplug the switch and measure resistance across the signal and return pins in each position, comparing with the specified table
- Check the connector and the clockspring pigtail for corrosion, distorted pins and chafing under the column shrouds
- Look for water tracking down the steering column, which is a frequent cause on this circuit
- Replace the multifunction switch with the correct part number when its resistance steps are out of specification
- Verify module power and ground quality before considering a body control module replacement
