85 & 86 are the control side of the relay , one should have battery voltage (85) the other (86) doesn't .86 is control from the PCM - engine computer . PCM supplys a ground to close contacts inside the relay sending battery voltage to the S terminal on the starter solenoid . If the PCM doesn't see a voltage signal fron the park neutral safety switch it won't energize the relay .
Circuit Description (ECM/PCM Controlled)
Moving the ignition switch to the START position sends a 12-volt signal to the engine control module (ECM)/powertrain control module (PCM) Crank Request circuit. The ECM/PCM verifies that the transmission is in the PARK or NEUTRAL position. With the transmission in Park, voltage flows through the Park/Neutral position switch and feeds the starter relay coil. The PCM then grounds the control circuit of the starter relay. When the starter relay is energized it allows battery positive voltage to the starter solenoid S terminal. On some vehicles the starter will continue to crank the engine with the key released until it starts or the crank command has timed out to prevent excessive heat build up in the starter circuitry or the ECM/PCM receives an engine run flag.

Definition of check engine code P0121:
Generic (Common for all car manufacturers):
Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance Definition of check engine code P0573:
Generic (Common for all car manufacturers):
Brake Switch "A" Circuit High

That won't cause a catastrophic failure. The electric servo for the brake will possibly have failed as you describe but the brakes will always still work, unless fluid was too low to catch in the pump.
Possible customer error perhaps but I have no access to the vehicle in question.
The manufacturers agent will find out what happened.

THERES A KEY ON THE SHAFT. YOU MAY NEED TO DOUSE IT WITH PENETRATING OIL FOR A FEW DAYS. MAYBE RUSTED ON IF YOU NEVER HAD IT OFF BEFORE
