Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. When the ignition is turned ON, the brake warning
lamp should initially illuminate and then dim for ABS
equipped vehicles. This is done as a bulb check.
On vehicles that are not equipped with ABS, the
brake warning lamp should only illuminate when
either the brake fluid reservoir is low or the parking
brake is applied.
7. The brake fluid level switch is a normally open
switch. If the brake warning lamp is off after discon-
necting the switch, the brake fluid level switch is
stuck closed.9. If the brake warning lamp is still on after discon-
necting the parking brake switch, there is a short to
ground in the wire to the parking brake switch.
12. If the other checks have been properly performed
and the brake warning lamp is off after disconnect-
ing the electronic brake control module (EBCM) J1
connector, the EBCM is faulty.
19. If the brake warning lamp does not operate while
performing any of the functions, the fault should be
in the ignition feed to the circuit.
24. This step determines if the problem is in the ignition
feed to the circuit or in the instrument cluster.
30. The brake warning lamp should illuminate when
jumpering the parking brake connector to ground.
32. If the brake warning lamp is on after jumpering the
brake fluid level switch terminals, the switch is
faulty.

ABS INDICATOR LAMP INOPERATIVE
Circuit Description
Battery voltage is supplied to the ABS warning lamp with
the ignition switch in the ON or START positions. The
warning lamp can be activated only by the ABS control
module internally supplying ground to terminal 20 or by the
shorting bar in the ABS module connector when it is dis-
connected from the module.
Diagnosis
This procedure checks for a problem in the wiring, a faulty
ground, a voltage supply problem, a burned out indicator
lamp, or a contact problem in a connector.
Cause(s)
S A fuse has blown.
S The indicator lamp has burned out.S There is a corroded or broken connector terminal.
S There is a faulty ground connection.
S There is a broken wire in a wiring harness.
S The EBCM is faulty.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This test checks for any DTCs that may cause the
ABS indicator lamp to be inoperative.
2. This test verifies an inoperative lamp condition.
3. This test checks for voltage on the lamp circuit.
4. This begins a series of tests of the circuit from the
indicator lamp to the EBCM and ground.
19. This begins a series of tests of the voltage supply
circuits that power the indicator lamp.

POWER SUPPLY TO CONTROL MODULE, NO DTCS
STORED
Circuit Description
Battery voltage is supplied to the electronic brake control
module (EBCM) through fuse F11 in the I/P fuse block, to
terminal 15 of the EBCM connector. The voltage is present
when the ignition switch is in the ON or START position.
Diagnosis
This test checks for battery output, proper grounding,
blown fuses, a faulty ignition switch, and problems in the
circuitry.
Cause(s)
S The battery is defective.
S There is a defective ground connection.
S A connector is damaged.
S A wire is broken or shorted.
S A fuse is blown.
S The ignition switch is malfunctioning.Fail Action
ABS action is disabled during the period of low voltage.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This step determines whether there is voltage at
the battery and the high current source.
7. This step checks for voltage at the ignition 1
source.
11. This step begins the check for voltage at the EBCM
end of the ABS harness.
15. This step checks for a defective ground connection.
16. This is a check for a defective EBCM connector.
Diagnostic Aids
It is very important to perform a thorough inspection of the
wiring and the connectors. Failure to do so may result in
misdiagnosis, causing part replacement with a reappear-
ance of the malfunction.
