Handset voltage too low

Voltage is too low for normal 

operation.

1. Check voltage of vehicle 

during ignition cranking.

2. Replace ECU.
3. Replace handset.

RF error

High levels of RF interference 

detected

1. Verify if client was using a 

mobile phone or in an area of 

high RF signal interference 

during use. If yes no action is 

required.

2. Replace handset.

Software incompatible

potentially blown.

1. Confirm that vehicle voltage 

reaching ECU is sufficient.

2. Replace ECU.

CALIbRATION pROCEdURES

It is recommended calibration be done indoors in a service facility, using an ACS 

download station.
The calibration procedures are intended for use by trained technicians only.

EqUIpMENT NEEdEd

•  130PPM (0.05 %BAC) Alcohol gas standard ACS #95-000425
•  Regulator valve assembly (6L/min. flow rate) ACS #94-000225
•  V3 Download station ACS #79-006111
