i. If the motor vehicle is in regeneration mode, then the vehicle cannot be inspected;

ii. Turn off the motor vehicle's engine;

iii. Turn the motor vehicle ignition system to the KOEO position; and

iv. If the DPF light is not functional, the motor vehicle has failed the indicator light check test;

3. If the vehicle is equipped with a SCR, determine if the SCR is functional as follows:

i. Turn off the motor vehicle's engine;

ii. Turn the motor vehicle ignition system to the KOEO position;

iii. If the SCR light is not functional, the motor vehicle has failed the indicator light check test;

iv. If the DEF tank gauge indicates empty or no fluid, the motor vehicle has failed the inspection.
