1. Check the ABSECU fuse

a. Ignition switch:LOCK. DI
b. Check if the ABSECU fuse F02 in the fuse box of instrument panel is broken.
If the fuse is broken? EG

a. Ignition switch:LOCK. AX
b. Disconnect ABSECU Connector B063
FR
c. Measure the resistance between No 4 and 9 terminals of
ABS ECU connector with a multimeter.
Standard resistance: ST

Multimeter connecting terminal Standard value
BR
B063(4)-grounding About 0Ω

B063(9)-grounding About 0Ω BW

d. Ignition switch:LOCK. EL

e. Check the voltage between No.7 and 8 terminals and the
ground of ABSECU connector B063.

Standard voltage:

Multimeter connecting terminal Standard value

B063(7)-grounding About 24V

B063(8)-grounding About 24V

Check if the result is ok?

Yes>repair ABSECU power supply and grounding circuit.

NO>go to Step 3.
