M2 Repeatability Drive Test (Low Output)

NOTE: Recording the speeds for later plotting will eliminate the necessity of monitoring the New Generation Star (NGS) tester while driving.

- Use the New Generation Star (NGS) tester to monitor all three wheel speeds. Accelerate smoothly and gradually until 20 mph speed is reached. Hold vehicle at 20 mph for at least 15 seconds and then decelerate.

- Does the speed signal from the right front brake antilock sensor remain at zero while the signals from the left front brake antilock sensor and the vehicle speed sensor indicate acceleration above 4 mph?
YES -- Concern is repeatable. Go to M4.

NO -- signal from the right front brake antilock sensor follows closely with the signals from the left front brake antilock sensor and vehicle speed sensor. Go to M3.
