TROUBLESHOOTING

ANTI-SKID BRAKING SYSTEM (ABS)

• System shutdown by ECU 

While ABS-ECU is disabled by the diagnostic 
function, the M.U.T.-III displayed data is different 
from the actual measurement.

ACTUATOR TEST REFERENCE TABLE

M1352011601274

Using M.U.T.-III, the following actuators can be forci-
bly operated:

TROUBLESHOOTING

ANTI-SKID BRAKING SYSTEM (ABS)

35B-56

NOTE: 

.

•

ABS is operated by ABS-ECU.

•

When ABS-ECU is disabled due to the fail-safe 
function, the actuator test cannot be performed.

•

The actuator test can be performed only when 
the vehicle is stationary.

•

While the actuator test is performed, the ABS 
warning lamp flashes at a rate of 2 Hz.

•

After the actuator test has been performed, the 
brake warning lamp and ABS warning lamp illu-
minate until the ignition switch is turned to ON 
again or the communication between M.U.T.-III 
and ABS-ECU is terminated.

1. Operate the lock lever to disconnect the 

ABS-ECU harness connector as shown in the 
figure.

2. Disconnect the ABS-ECU connector, and 

measure the voltages between earth terminal 
No.13 or No.38 and each respective terminal.

3. The terminal layout is shown in the illustration.

NOTE: Do not measure terminal voltage for approxi-
mately three seconds after the ignition switch is 
turned to the "ON" position. The ABS-ECU performs 
the initial check during that period.
