10-8 (2) Pre-heating time control based on battery voltage GCU monitors the battery voltage. If it is low, GCU extends the pre-heating time. GCU monitors the energy to glow plugs (the amount of pre-heating energy is always same). - - GCU monitors the battery voltage. If it is low, GCU extends the pre-heating time to get enough energy. - GCU monitors the battery voltage. If it is low, GCU increases PWM duty.. - |
