Subaru Select Monitor

OPERATION

GENERAL DESCRIPTION
For the on-board diagnosis function of the cruise control system, use 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 content of memory is cleared when ignition switch or cruise control main 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.
