- Install a 3A fused jumper wire between the 5-volt reference terminal A and 5 volts. Install a jumper wire between the low reference terminal C and ground.
- Sweep the suspension position sensor through the entire range while monitoring the voltage between the signal terminal B and the low reference terminal C. The range should vary between 0.35-4.75 volts without any spikes or dropouts.
- If not within the specified range or if it is erratic, replace the suspension position sensor.
