Input signals
Accelerator pedal position sensor
Clutch switch
Transmission neutral switch
Exhaust brake switch
• The auxiliary brake function activates or deactivates the exhaust shutter 3-way magnetic valve according to the
vehicle condition to control the exhaust brake.

2.8 Idle-up function

• The idle-up function increases the engine idling speed when a load is applied to the engine by other system (such
as air conditioner) or when the warm-up acceleration function are activated.

2.9 Fault diagnosis function

• The sensors and other components are continuously monitored for faults. In the event that a component is found
faulty, an indication is made in the meter cluster to alert the driver, the fault location is memorized in the form of a
diagnosis code, and the control during fault is initiated.
• While the control during fault is taking place, the system's functionality is limited to ensure vehicle and driver safe-
ty. It is possible to read the memorized diagnosis code using a Multi-Use Tester or from flashing of the warning
lamp.
• The control during fault recovers by servicing the faults. However, for some diagnosis codes, the warning lamp
stays illuminated until the normal signals are input for several times.
• Diagnosis codes shown by the Multi-Use Tester and those indicated by flashing of the warning lamp are different.
• The Multi-Use Tester is capable of showing more detailed diagnosis codes.
