Gain Adjustment P92

Check the gain jumper to determine which setting it is on. The gain jumper is set at the factory at the number one setting. This setting is the second set of pins from the left. If after setting the RV2, a slight surge is felt at 34 km/h (55 mph), the gain can be increased by moving the jumper to a higher setting. If the jumper is set higher than number one, another technician may have moved it. If the cruise control system is operating correctly, do not move the jumper.
