TEST CONDITIONS
Check driver select switch input pins for valid input combination: (1) pin C4 ("Normal" input) grounded and pin C5 ("Firm" input) open, or (2) pin C4 open and pin C5 grounded.

FAULT CONDITIONS
If both switch inputs are open or both are closed to ground (active) for more than 3.0 seconds, set code.

ACTION TAKEN
Record driver select switch error.

DESCRIPTION
A driver select switch input error is detected when both switch inputs (connector pins C5 and C6) are asserted (grounded) or both are unasserted (open) for more than 3.0 seconds consecutively. If a driver select switch input error is detected, the system will default to the "Normal" switch setting and set code 33.
