CN5-68 L/R EGR valve relay exciting coil
Power supply (DC12V) of EGR valve relay
exciting coil
CN5-69 Br/B Cleaning exhaust filter lamp
When soot is so much accumulated on DPF that
cleaning is required, it lights on while cleaning is
performed.
CN5-70 L/G Glow plug relay exciting coil
No power exists during usual operation.
Preheating begins when ECU CN5-88 terminal is
electrified. Glow plug relay coil is electrified to
start preheating.
CN5-71 Br/R Regeneration lamp
When manual regeneration is required, it makes
regeneration lamp flicker. During manual
regeneration the lamp changes from flickering to
lighting.

CN5-76 Br/B EGR valve DC motor
It operates EGR DC motor, and it controls valve
lift of EGR valve.
ECU decides EGR gas volume based on engine
speed and engine load ratio (fuel injection
volume) and it operates EGR valve by EGR DC
motor, and also it controls EGR gas volume to be
mixed in engine intake air.
