Katool Wheel Balancer Error Code 006 Diagnostics

Step 1: Verify Circuit Board Voltage

1.Set your multimeter to measure 20V DC voltage.

2.Locate the circuit board test points labeled: 
GND (Ground) 
+5V 
-5V 

3.Check +5V Supply: 
Place the black (negative) probe on the GND point. 
Place the red (positive) probe on the +5V point. 
The multimeter should read approximately +5.00V DC. 

4.Check -5V Supply: 
Keep the black (negative) probe on the GND point. 
Move the red (positive) probe to the -5V point. 
The multimeter should read approximately -5.00V DC. 

5.Evaluate Results: 
If readings are close to +5V and -5V and not below or above (Example: +3V and -3V) the circuit board is receiving proper voltage and operates within normal limits. 
If readings are outside this range or missing, further diagnosis of the power supply or replacement of the circuit board is required.

6.Power supply:
Always make sure that the outlet you’re using is in good condition, and reading at an adequate 110v or greater for proper working conditions for your wheel balancer.

Step 2: Check circuit board main cable for damage.

1.Locate the main cable on the wheel balancer’s circuit board. 
The main cable should be a 20-pin adapter cable that hooks up to the circuit board and runs from circuit board up to the display board inside the balancer’s screen. 

Locate and inspect that cable for any rips/tears.

Damage to this cable has the potential to trigger error codes on the machine. Error 006 being the most common.
If damage is noticed to these cables and or voltage to your circuit board is not reading within normal limits upon receiving an error code 006, please contact our technical support team here: Katool Tech Support
