Wiring Diagram:

TEST CONDITIONS
Check for vehicle speed signal during periods when vehicle movement is suspected.

FAULT CONDITIONS
If vehicle speed signal is not detected for 20 seconds, followed by 5 or more transitions in lateral accelerometer input, set code.

ACTION TAKEN
Record vehicle speed signal error. System will continue to default to zero speed damping level (firm).

DESCRIPTION
A vehicle speed signal error occurs when the Control Module detects 5 or more transitions in the lateral accelerometer input after 20 or more seconds without a vehicle speed input. If a fault is detected the system will set error code 34.

NOTES ON INTERMITTENTS
