General Description

SUBARU SELECT MONITOR

OPERATION

GENERAL DESCRIPTION
The on-board diagnosis function of the cruise control system uses Subaru Select Monitor.
The on-board diagnosis function operates in two categories, which are used depending on the type of problems;

1. Cruise Control Cancel Conditions Diagnosis:
1. This category of diagnosis requires actual vehicle driving in order to determine the cause, as when cruise speed is cancelled during driving although cruise cancel condition is not entered.
2. Cruise control memory in ECM stores the cancel condition (Code No.) which occurred during driving. When there are multiple cancel conditions (Code No.), they are shown on the Subaru Select Monitor.

CAUTION:
- The cruise control memory stores not only the cruise cancel which occurred (although cancel operation is not entered by the driver), but also the cancel condition input by the driver.
- The latest memory content (latest code) is cleared when ignition switch is turned to OFF. However, the memory content by the diagnosis of faulty switches relating to the system and cruise control is retained as the fault history (memory code) after the ignition switch is turned OFF.

2. Real-time Diagnosis:
Real-time diagnosis function is used to determine whether or not the input signal system is in good order, according to signal emitted from switches, sensors, etc.
1. Vehicle cannot be driven at cruise speed when the problem occurs in the cruise control system or relevant circuits.
2. Monitor the signal conditions from switches and sensors.
