For 1990-2009 cars

### Conditions for Setting the DTC

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, activate both position L.E.D.s, and set code 33.

### Action Taken When the DTC Sets

1. Record driver select switch error.
2. Turn on both L.E.D.s.
3. Default to Touring setting until a valid switch input combination is detected.
