Blink Codes
Note: -
In case of error no. 52, 53, 54 i.e. Temperature
Warning Light Fault, the reasons for this error to occur
are different (like signal error, short circuit to ground,
short circuit to battery). For all the three reasons the
error description remains the same & blink code is
also same i.e. 43.
