Antitheft Relay: Description and Operation STARTER INTERRUPT RELAY/HEADLIGHT ALARM RELAY
The starter interrupt relay, activates by a signal from the security control module, interrupts the starter circuit keeping the starter from operation. In armed state, the system will not activate the starter interrupt relay and starter circuit functions normally. The system activates the starter interrupt relay when the system is in alarm state, and keep this condition until the system is turned to disarmed state. The headlight alarm relay is adopted in headlight circuit, and this relay activates when the security system is in alarm state. In alarm state, the security control module switches the output signal ON-OFF alternately to flash the headlight via a headlight alarm relay. The starter interrupt and headlight alarm relays employ the same parts and are interchangeable. The starter interrupt relay and headlight alarm relay are installed behind the lower cover located under the steering column.

Electronic Brake Control Module: Description and OperationABS
ABS CONTROL MODULE (ABS C/M)
­The ABS control module determines the state of the wheels based on input signals from the ABS sensor, and optimally increases or decreasesbrake fluid pressure by controlling the electric current flowing through magnet valves built into the hydraulic unit.
­ABS control module perf6rms logical computation and monitoring on each of two 8-bit microcomputers, creating a fail-safe system by whichsystem failures can be detected.
-
This ABS control module detects open circuits by sending an electrical current through the sensor system. An upper limit is established withrespect to the sensor signal input characteristics, and if an input value exceeds that limit it is considered a failure. Figure shows [a marginal level] afailure.
-
A maximum of 3 trouble codes are stored in the EEP ROM and if 3 or more areas fail, then only the 3 most recent failures are stored. The troublecodes remain stored until they are erased. The trouble codes can be determined by the flashing of the ABS warning light located in thecombination meter This ABS control module induces a sequence control pattern and facilitates the checking of the hydraulic unit.

Electronic Brake Control Module: Description and OperationABS/TCS
ABS/TCS CONTROL MODULE
-
The C/M of this system is a digitally controlled electronic control module equipped with two 8-bit CPUs of main and sub ones. The C/M not onlylogically processes wheel speed signals for the ABS control and 105 control (brake control) functions but has the self-diagnosis function, fail-safefunction, and Subaru select monitor communication function. The C/M is installed under the front right seat.
-
Page 23
The trouble codes of all the failures that occurred in the past are stored in the EEPROM. (When the same failure occurs twice or more, the troublecode of the most recent failure is stored only once.) The trouble codes remain stored until they are erased. The trouble codes can be determined bythe flashing of the TCS warning light located in the combination meter This ABS/TCS control module induces a sequence control pattern (ABS,TCS) and facilitates the checking of the hydraulic unit.

Electronic Brake Control Module: Description and OperationABS [5.3 Type]
ABS CONTROL MODULE (ABSCM)
The ABSCM is a digital control type electronic control module accommodating two microcontrol modules (MCMs); master and slave. BothMCMs process the same program and monitor the respective outputs, and when a mismatch occurs, cut off the system to activate the fail-satefunction.A maximum of 3 trouble codes are stored in the EEP ROM and if 3 or more areas fail, then only the 3 most recent failures are stored. The troublecodes remain stored until they are erased.This ABSCM induces a sequence control pattern and facilitates the checking of the hydraulic unit.
ABS CONTROL
Based on the four wheel speed signals, the ABSCM calculates a simulated body speed or body deceleration rate, while referencing the G sensoroutput as an auxiliary means, and compares them with the wheel speeds and wheel deceleration rates. If it determines that the wheels are about tolock, it controls the solenoid valve or motor pump of the H/U to adjust the brake fluid pressures that act on the wheel cylinders, thereby preventingthe wheels from locking.The ABSCM controls the right and left front wheel fluid pressures independently and controls the rear wheel fluid pressures on the basis of thewheel which is more likely to lock (Select-low control).
SELECT MONITOR ASSOCIATED FUNCTIONS
The Subaru select monitor may be used to perform the following operations.
(1) To read out analog data(2) To read out ON/OFF data(3) To read out or erase trouble code(4) To read out status information in the event of trouble (Freeze frame data)(5) To initiate ABS sequence control pattern
INDICATION FUNCTIONS
The ABS warning light can be made to indicate the following three states.
(1) ABS trouble(2) Flashes to indicate trouble codes in diagnosis mode.(3) Valve ON/OFF when sequence control pattern is in effect.

Exterior Lighting Module: Diagnostic Aids
Basic Diagnostic Procedures
The most important purpose of diagnostics is to determine which part is malfunctioning quickly, to save time and labor.
A. Identification Of Trouble Symptom
Determine what the problem is based on the symptom.
B. Probable Cause Of Trouble
Look at the wiring diagram and check the system's circuit. Then check the switch, relay, fuse, ground, etc.
C. Location And Repair Of Trouble
1) Using the diagnostics narrow down the causes.2) If necessary, use a voltmeter, ohmmeter, etc.3) Before replacing certain component parts (switch, relay, etc.), check the power supply, ground, for open wiring harness, poor connectors, etc.
If no problems are encountered, check the component parts.
D. Confirmation Of System Operation
After repairing, ensure that the system operates properly.
Circuit Continuity Checks
Circuit Continuity Checks
1) Disconnect the battery terminal or connector so there is no voltage between the check points. Contact the two leads of an ohmmeter to each of the check points.If the circuit has diodes, reverse the two leads and check again.
2) Use an ohmmeter to check for diode continuity.
Circuit Continuity Checks
Page 91
> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions
> Page 92
Outback [Legacy] AWD F4-2.5L DOHC (1996)
When contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity.When contacting the two leads in reverse, there should be no continuity.
3) Symbol "o__o" indicates that continuity exists between two points or terminals. For example, when a switch position is "3", continuity exists among terminals 1, 3 and 6, as shown in the image.
How to Determine A Short Circuit
Page 92
Test Lamp Method To Determine A Short-Circuit
1) Test lamp method
3 W
Connect a test lamp (rated at approximately ) in place of the blown fuse and allow current to flow through the circuit. Disconnect oneconnector at a time from the circuit, starting with the one located farthest from the power supply. If the test lamp goes out when a connector isdisconnected, the wiring between that connection and the next connector (farther from the power supply) is shorted.
Ohmmeter Method To Determine A Short-Circuit
2) Ohmmeter method
Disconnect all affected connectors, and check continuity between each connector and ground. When ohmmeter indicates continuity between aparticular connector and ground, that connector is shorted.
How to Determine an Open Circuit
Voltmeter Method To Determine Open Circuit
1) Voltmeter method
ON
An open circuit is determined by measuring the voltage between respective connectors and ground using a voltmeter, starting with the connectorclosest to the power supply. The power supply must be turned so that current flows in the circuit. If voltage is not present between a particularconnector and ground, the circuit between that connector and the previous connector is open.

Ohmmeter Method To Determine Open Circuit
2) Ohmmeter method
Disconnect all connectors affected, and check continuity in the wiring between adjacent connectors. When the ohmmeter indicates "infinite", the
Page 94
wiring is open.
Voltage Measurement
Voltage Measurement
1) Using a voltmeter, connect the negative lead to a good ground point or negative battery terminal and the positive lead to the connector or component terminal.
2) Contact the positive probe of the voltmeter on connector (A). The voltmeter will indicate a voltage.
3) Shift the positive probe to connector (B). The voltmeter will indicate no voltage.
With test set-up held as it is, turn switch . The voltmeter will indicate a voltage and, at the same time, the light will come on.ON
4) The circuit is in good order. It a problem such as a lamp failing to light occurs, use the procedures outlined above to track down the malfunction.
