QUICK-GLOW SYSTEM — Description
EF & EC-711prose procedureCD17-specific behavior noted: vehicle-speed cutoff at 12 km/h (7 MPH) to protect glow plugs. Vehicle speed sensor input noted as (CD17).
Description
When the ignition key is inserted into the key cylinder, the control unit turns on the relay and the "high-level" electric current flows through the glow plugs and heats them up quickly. When the ignition switch is turned on, the control unit turns on the indicator. After T1 seconds have passed from key in, the control unit turns off the indicator.
While cranking, the relay remains on. The relay automatically turns off after T4 seconds have passed from the engine start. For CD17: When vehicle speed exceeds 12 km/h (7 MPH), the control unit stops the electric current to glow plugs to protect them.
