DATA LINK CONNECTOR DIAGNOSIS
Circuit Description
The provision for communicating with the Engine Con-
trol Module (ECM) is the Data Link Connector (DLC). It
is located under the instrument panel. The DLC is used
to connect the scan tool. Battery power and ground is
supplied for the scan tool through the DLC. The Key-
word 2000 serial data circuit to the DLC allows the ECM
to communicate with the scan tool. A Universal Asyn-
chronous Receiver Transmitter (UART) serial data line
is used to communicate with the other modules such as
the Electronic Brake Control Module (EBCM), the Sup-
plemental Inflatable Restraint (SIR) system. and the In-
strument Panel Cluster.
Diagnostic Aids
Ensure that the correct application (model line, car year,
etc.) has been selected on the scan tool. If communica-
tion still cannot be established, try the scan tool onanother vehicle to ensure that the scan tool or cables
are not the cause of the condition.
An intermittent may be caused by a poor connection,
rubbed through wire insulation, or a broken wire inside
the insulation.
Any circuitry that is suspected of causing an intermittent
complaint should be thoroughly checked for the follow-
ing conditions:

Backed-out terminals.

Improper mating of terminals.

Broken locks.

Improperly formed or damaged terminals.

Poor terminal-to-wiring connection.

Physical damage to the wiring harness.

Corrosion.

4A – 2 HYDRAULIC BRAKES
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
WARNING LAMP OPERATION
This brake system uses a BRAKE warning lamp located
in the instrument panel cluster. When the ignition switch
is in the III position, the BRAKE warning lamp should il-
luminate. It should go off when the ignition switch return
to II position. The following conditions will activate the
BRAKE warning lamp.

The lamp should be on whenever the parking brake
applied and the ignition switch is in the II position.

A low fluid level in the master cylinder will turn the
BRAKE warning lamp on.

WARNING LAMP OPERATION
This brake system uses a BRAKE warning lamp located
in the instrument panel cluster. When the ignition switch
is in the III position, the BRAKE warning lamp should
glow and then go OFF when the ignition switch returns
to the II position.The following conditions will activate the BRAKE lamp:

Parking brake applied. The light should be on when-
ever the parking brake is applied and the ignition
switch is II.

Low fluid level. A low fluid level in the master cylinder
will turn the BRAKE lamp ON.

4G – 2 PARKING BRAKE
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
PARKING BRAKE
This braking system uses a BRAKE warning light lo-
cated in the instrument panel cluster. When the ignition
switch is in the III position, the BRAKE warning light
should glow and go OFF when the parking brake lever is
released. Whenever the parking brake is applied and theignition switch is II, the BRAKE warning light should
glow.
When the brake is firmly applied, the parking brake
should securely hold the vehicle with ample pedal travel
remaining. Check for frayed cables, rust, etc., or any
condition that may inhibit present (or future) free move-
ment of the parking brake lever assembly.
