Summary

A WIRE FROM THE STOP LAMP SWITCH TO THE SPEED CONTROL AMPLIFIER IS MISSING. THIS WIRE SENDS A SIGNAL TO THE CRUISE CONTROL TO DISENGAGE WHEN THE BRAKES ARE APPLIED. CONSEQUENCE OF DEFECT: WHEN THE CRUISE CONTROL IS ON AND THE BRAKES ARE APPLIED, THE CRUISE CONTROL WILL NOT DISENGAGE. THIS CAUSES THE AMBULANCE SPEED TO REMAIN CONSTANT, CAUSING POOR BRAKE PERFORMANCE AND LOSS OF SPEED CONTROL WHICH CAN RESULT IN AN ACCIDENT.

Remedy
