Note on Intermittents
If an intermittent Code B667 is being set, manipulate related wiring while observing BI76 and BI77 displays. If failure is induced, reading will jump from LO to HI with the switch in the OFF position (not depressed). This code can also be set by vehicle operator if cruise ON/OFF switch is turned to the ON position, or the ON/OFF switch was left in the ON position when ignition is turned on and vehicle operator was depressing either the SET/COAST or RESUME/ACCEL switches.
