ABS Actuator and Electric UnitNJBR0162Disconnect each ABS actuator and electric unit E217 connector.
Confirm continuity and resistance value between each pair of ABS
actuator and electric unit harness connector.
CAUTION:
Be sure ABS motor is securely grounded.
Basic Inspection 1 Brake Fluid Level and
Leakage Inspection
NJBR01631. Check fluid level in brake reservoir tank. If fluid level is low,
refill brake fluid.
2. Check area around brake piping and ABS actuator and elec-
tric unit for leaks. If a leak or oozing is detected, check as fol-
lows:
If connections at ABS actuator and electric unit are loose,
tighten piping to the specified torque. Then check again for
leaks, and be sure there is no fluid leak.
If the flare nuts at the connections and the threads of the ABS
actuator and electric unit are damaged, replace the damaged
parts. Then check again for leaks, and make sure that there is
no fluid leak.
If leak or oozing is detected except for ABS actuator and elec-
tric unit connections, wipe it with clean cloth. Then check again
for leaks. If there is still leak or oozing, replace damaged part.
If leak or oozing is detected on ABS actuator and electric unit,
wipe with a clean cloth. Check again for leaks, and if there is
still leak or oozing, replace ABS actuator and electric unit.
CAUTION:
ABS actuator and electric unit body cannot be disassembled.
Basic Inspection 2 Inspection for Loose Power
Supply Terminal
NJBR0164Check battery for looseness on battery positive/negative terminals
and ground connection.

Inspection
NJBR01651. Be sure ABS warning lamp turns on when ignition switch is
turned ON. If it does not turn on, check ABS warning lamp
harness.
2. Be sure ABS warning lamp turns off after approximately 1
second when ignition switch is turned ON. If it does not turn off,
perform self-diagnosis.
3. After driving the vehicle at Approx. 30 km/h (19 MHP) for a few
seconds, check ABS warning lamp do not illuminate.
4. After completing the self-diagnosis, always erase the diagno-
sis memory.GI
