DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS operation.
This DTC is stored when the +BS terminal voltage deviates from the DTC detection condition due to a malfunction in the power supply or charging circuit such as the battery or generator circuit, etc.
The DTC is canceled when the +BS terminal voltage returns to normal.

PROCEDURE
1. |
INSPECT BATTERY |
(a) Check the battery voltage.
Standard voltage:
11 to 14 V
NG | ![]() |
CHECK OR REPLACE CHARGING SYSTEM OR BATTERY |
|
2. |
CHECK TERMINAL VOLTAGE (+BS TERMINAL) |
(a) Turn the ignition switch off.
(b) Make sure that there is no looseness in the locking part and connecting part of the connectors.
(c) Disconnect the skid control ECU (brake actuator assembly) connector. |
|
(d) Measure the voltage according to the value(s) in the table below.

REPAIR OR REPLACE HARNESS OR CONNECTOR (+BS CIRCUIT) |
|
3. |
CHECK HARNESS AND CONNECTOR (GND1 TERMINAL) |
(a) Turn the ignition switch off.
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
NG | ![]() |
REPAIR OR REPLACE HARNESS OR CONNECTOR (GND1 CIRCUIT) |
|
4. |
RECONFIRM DTC |
(a) Reconnect the S1 skid control ECU (brake actuator assembly) connector.
(b) Clear the DTC (See page
).
(c) Turn the ignition switch off.
(d) Start the engine.
(e) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(f) Check if the same DTC is recorded (See page
).
HINT:
If troubleshooting has been carried out according to the Problem Symptoms Table,
refer back to the table and proceed to the next step (See page
).
