FIGURE 29 - EGR SYSTEM PAGE (25-15)
Page 25-15 - Figure 29 has been replaced. The new picture is included at the back of this bulletin.
COLT 81-270-3006
Page 25-17 - The first line of the description of thermo valve should read "the thermo valve incorporated in the EGR system" instead of "two thermo
valves incorporated."
COLT/RAM-50 81-370-3009
Page 8-74 - The General section has been changed to read as follows:
General
The dropping resistor method has been adopted to the QGS.
^
The dropping resistor takes the role of resistance to decrease voltage to the glow plug.
^
The relay changes the dropping resistor circuit.
^
An ultra-quick heating method has been adopted to the glow plug.
^
A change control circuit to change circuit to heating circuit has been adopted to the control unit.
The QGS has two main circuits to maintain the glow plug at constant temperature and to shorten the pre-starting time. One is the quick heat circuit,
which applies battery voltage (12 volts) to the glow plug.
The other is the heat stabilization circuit which decreases voltage applied to the glow plug, by changing the power source circuit to the dropping circuit,
when the glow plug reaches the design temperature.
