Is the voltage greater than 10 volts?

Yes

GO to B3.

If the stoplamps operate, REPAIR circuit 15-PG6 (GN/YE). TEST the system for normal operation If the stoplamps do not operate, REFER to EXTERIOR LIGHTING .

B3 CHECK CIRCUIT 15S-PG16 (GN/YE) FOR OPEN

Key in OFF position.
Disconnect: Speed Control Actuator C122.
Measure the resistance between the BPP switch C278, pin 1, circuit 15S-PG16 (GN/YE), and the speed control C122 pin 9, circuit 15S-PG16 (GN/YE), harness side.
