ABS codes 45, 49, 62

[Gasman GT3]

Hooked up Espritmon today to see which ABS sensor if any had failed putting the ABS light on.  Indeed the front LH side is showing a fault, but I am getting three fault codes 45,49,& 62.  In addition to the sensor fault what other issues are these codes related to?

Code 45 - left front wheel speed

Code 49 - Excessive left front wheel acceleration

Code 62 - low accumulator precharge

 

Likely a left wheel sensor issue and possibly bad accumulator, or wiring between the two
