AXM & AXL Series Trouble Shooting

What does ER1 mean?

Possible Cause: Invalid calibration. Caused by “LO” and “HI” set at the same time either empty or full.

Solution: Recalibrate “LO” value at unladen/empty weight and “HI” value at laden/full weight.

What does ER2 mean?

Possible Causes: The calibrated weight of the “LO” value is too close to the calibrated weight of the “HI” value.Solution: Recalibrate the “LO” value at minimum/empty weight and “HI” at maximum weight.

My truck scales are displaying inaccurate readings

Probable cause:The gauge wasn’t calibrated or was set with incorrect weight on the weighbridge.

Solution:Keep the engine running to provide air to the suspension system. Park the trailer on the level ground. Release trailer brakes. Exhaust the air from the suspension and inflate to correct ride height.

Probable cause: The gauge is not connected to the air-bag suspension.

Solution:Check the air-line connection.

My truck scale display is always on

Probable Cause: Display Auto OFF timer mode not set.

Solution: Set display auto OFF timer.

My truck scale display turns off too quickly

Probable Cause: The time value set for the display auto OFF timer mode is too low.

Solution: Adjust or increase display timer mode

My truck scale display isn't turning on

Probable Cause: Check if unit is connected to power.

Solution: Check the power circuit. If the voltage is below 8 DC the unit will not function correctly. Test the power source with a voltmeter. The gauge must be connected to a switched source to allow occasional software reboot.

Probable cause: Check if the polarity is correct

Solution: The red/brown wire must be connected to positive, and the black to negative.

My truck scales are displaying unstable readings

Probable Cause: The height control valve (HCV) is malfunctioning or broken.

Solution: The HCV is not functioning correctly, the air pressure applied to the suspension system could be inconsistent.

Probable Cause: The height control valve (HCV) cannot supply air to the suspension system.

Solution: Set unit into Pressure Gauge Mode to display actual air pressure). Then, check and replace ride height control valve.
