Kia Niro: Engine Control System / Injector Troubleshooting
| Signal Waveform |
The three waveforms below are taken from the #1 and #4 injectors. The top waveform is from the high side (feed side) of the #1 and #4 injectors, while the middle waveform is from the low side (ground side) of the #1 injector and the bottom waveform is from the low side of the #4 injector.
The middle waveform is the same as the top waveform because there is no ground for the circuit. With no current flowing in the circuit, the #1 injector is not energized and fuel does not flow.
The bottom waveform shows that ground is supplied and there is a voltage drop across the #4 injector. With current flowing in the circuit, the #4 injector is energized and fuel flows.

Kia Niro 2017 (DE HEV) Service Manual: Parking Brake Repair procedures
Inspection
Check whether the stroke is within specification when the parking brake pedal
is depressed with 66 lb, 294 N(30 kg) of force. Also, the parking brake alone should
securely hold the vehicle on a fairly steep grade. If the stroke is more or less
than specified, have the p ...
