Glow plug relay signal circuit
• When the glow plug relay is on, the current voltage signal of the relay below 1.0 V is inputted to the PCM continuously for more than 1.0 s.
• When the glow plug relay is off, the current voltage signal of the relay above 4.0 V is inputted to the PCM continuously for more than 1.0 s.
• Turns glow plug relay off.
