Component Testing
- Ignition OFF, disconnect the harness connector at the steering wheel switch assembly.
- Test for 0.5-O.L. ohms between the scroll wheel terminals listed below, while rotating each steering wheel scroll wheel several times through its full range of motion.
- right steering wheel scroll wheel terminal 1 and terminal 2.
- left steering wheel scroll wheel terminal 3 and terminal 4.
- If not within the specified range or is erratic, replace the steering wheel switch.
- Test the resistance between the signal terminal 6 and the low reference terminal 5 while depressing the appropriate steering wheel controls switch button listed below.
- If not the specified value, replace the steering wheel switch.
