How to clear code 74

[janderson]

I have a TK Super II Smart + that shows a 74 code fault. The unit runs fine but our drivers are always scared the unit is acting up because of the fault light burning. Can anyone please tell me how to clear this fault. Thank you

you have to get into guarded access,earlier posts describe how to do this,its up reverted to default ,you have to know what you are doing minefield if you get it wrong.

Turn cycle sentry off

Turn on/off On

Press TK key, and the "clear" key for 5 secs

This will bring you to guarded access

You can try and press the code key and then the clear key to see if the 74 goes away, if not

Press the select key till you get to DDUR 45

At DDUR 45 press and hold TK and Clear for 5 or more secs

Press the code key

Then press Clear

Turn on/off off and then place unit back in service.

Important do not change or modify any other parameters.

Code 74 is unit reset to default look here http://www.trailerservices.com/resources/TK_Alarm_Codes.pdf

so if this is the case you need to re enter the parameters.
tell us what kind of micro(just describe how it looks if your not sure) you've got and if its got electric standby or modulation, the engine type, compressor type and its application, trailer mount?
