Measure the resistance between the speed control actuator C122-5, circuit VES10 (WH), harness side and the speed control actuator C122-6, circuit RES08 (GN/BN), harness side while pressing the speed control switches as follows:

Switch Position	Resistance Value (in Ohms)
OFF	Less than 5
ACCEL/SET	646-704
COAST	114-126
RESUME	2,090-2,310
No switch pressed	Greater than 10,000

Are the speed control switch resistance values OK?

YES : INSTALL a new speed control actuator. REFER to Speed Control Actuator . TEST the system for normal operation.
NO : INSTALL a new speed control switch. REFER to Speed Control Switch . TEST the system for normal operation.
