It's not unusual for the Trophy to throw up an error code or two after Low Voltage.
In particular "P1698" : "5 Volt sensor supply circuit malfunction" will often be logged.
It's easy to check any Error codes that have been stored,
and have them displayed on the Instrument Panel :
Press the SCROLL UP and SELECT (
"i" ) buttons together,
and hold them in while switching on the Ignition -
Keep them held in until the Speedo and Tacho needles have completed their Sweep
The screen should display "DTC" ( Diagnostic Trouble Codes )
with any DTC's that have been stored listed underneath.
If there are more than one, use the Scroll button to scroll through them.
"P0000" is what you wart to see - it means there are NO DTC's stored.
Make a note of any DTC's ( take a Photo ) and Switch the Ignition OFF when done.
Refer to Reply #8 dated Mar 11, 2015 titled "
Diagnostic Trouble Codes ( DTC's ) / Fault Codes" in this Topic :
Servicing Data, Reference Info. & DTC ( Fault ) Codesfor more information and a downloadable document listing all of the DTC's with their meanings,
and further information such as how many "No Fault" starts are required before the "MIL"
( Malfunction Indicator Light / Engine Management Light ) is extinguished,
and long they are held in Memory before being automatically cleared.
Report back with any DTC's that you find if you need further advice

Cheers
