TROUBLESHOOTING (ABS/TCS/DYNAMIC STABILITY CONTROL)
P–115
P
•
When performing an asterisked (*) troubleshooting inspection, shake the wiring harness and connectors while
doing the inspection to discover whether poor contact points are the cause of any intermittent malfunction. If
there is a problem, check to make sure connectors, terminals and wiring harnesses are connected correctly
and undamaged.

INSPECT PID/DATA IN ABS/TCS HU/CM
Inspect (BRAKE system warning light) using
WDS or equivalent PID/DATA monitor function.
Is BRAKE_LAMP on after
more than 4
seconds
with ignition switch on?
Yes
Connect ABS/TCS HU/CM connector terminal X securely,
then go to next step.
No
Go to step 6.
5
VERIFY WHETHER MALFUNCTION IS IN
PARKING BRAKE SWITCH OR BRAKE FLUID
LEVEL SENSOR, OR IN SOME OTHER PART
Disconnect the following in order:
1. Parking brake switch connector
2. Brake fluid level sensor connector
Does BRAKE system warning light go out with
ignition switch on?
Yes
Replace parking brake switch and/or brake fluid level sensor
(shorted on some internal part).
No
Perform the following inspections. Repair if necessary.
•
Short to ground in wiring harness between instrument
cluster ( BRAKE system warning light) and parking
brake switch.
•
Short to ground in wiring harness between instrument
cluster (BRAKE system warning light) and brake fluid
level sensor.
Inspect instrument cluster.

6
INSPECT WIRING HARNESS BETWEEN ABS/
TCS HU/CM AND DLC-2 (DATA LINK
CONNECTOR-2) FOR CONTINUITY
Disconnect ABS/TCS HU/CM connector.
Connect the
SST
( 49 G066 001) (vehicle
harness side only).
Is there continuity between
SST
connector
terminal X and data link connector?
Yes
Go to next step.
No
Repair wiring harness between ABS/TCS HU/CM and data
link connector.
*
7
INSPECT WIRING HARNESS BETWEEN ABS/
TCS HU/CM AND DLC-2 (DATA LINK
CONNECTOR-2) FOR SHORT TO B+
Is voltage
approximately 12 V
at
SST
connector terminal X?
Yes
Repair wiring harness between ABS/TCS HU/CM and data
link connector.
No
Go to next step.
*
8
INSPECT WIRING HARNESS BETWEEN ABS/
TCS HU/CM AND DLC-2 (DATA LINK
CONNECTOR-2) FOR SHORT TO GROUND
Is there continuity between
SST
connector
terminal X and ground?
Yes
Repair wiring harness between ABS/TCS HU/CM and data
link connector.
No
Replace ABS/TCS HU/CM (communication circuit
malfunction in ABS/TCS HU/CM).
