1993 MBZ is a OBD 1 type vehicle what you failed on is the function test , this is where the CK ENG LT. failed which would require you to replace the light bulb ,in the instrument cluster. As for the secondary air pump its function needs to be check and any missing air injection hoses need replaced.
