Replace the modulator unit.
Check for loose ABS/TCS control unit
connectors. If necessary, substitute a known-good
ABS/TCS control unit, and recheck.
1. Test-drive the vehicle, and apply the brake several
times to raise the brake temperature.
2. Raise the vehicle on a hoist, and check for
excessive brake drag.
Repair the cause of brake drag.
Go to step 3.
3. Check the installation of the appropriate wheel
sensor (see table).

1. Clear the DTC (see step 1 on page 19-83).
2. Test-drive the vehicle at 6 mph (10 km/h) or more.
Replace the modulator unit.
The system is OK at this time.
1. Check the ABS MOTOR (30A) fuse in the under-
hood fuse/relay box, and reinstall the fuse if it is OK.
Go to step 3.
Replace the fuse, and go to step 2.
2. Remove the pump motor relay from the under-
hood relay box. Connect pump motor relay
connector terminal No. 4 to No. 5 with a jumper
wire for a moment, and check the fuse.
Check for a short to body ground in the
motor power source circuit.
Go to step 3.
3. Remove the ABS MOTOR CHECK (7.5A) fuse in the
passenger’s under-dash fuse/relay box.
Remove the fuse, and go to step 4.
Replace the fuse, and recheck.
4. Turn the ignition switch ON (II).
5. Measure the voltage between the passenger’s
under-dash fuse/relay box connector J (16P)
terminal No. 5 and body ground.
Go to step 6.
Repair open in the wire between the
passenger’s under-dash fuse/relay box and the
ABS/TCS control unit.

connector terminal No. 1 and body ground.
Go to step 12.
Repair open in the wire between the under-
hood ABS relay box and pump motor.
12. Measure the voltage between modulator unit
connector terminal No. 1 and No. 16.
Replace the modulator unit.
Repair open in the wire between the pump
motor and body ground (G303).
13. Disconnect ABS/TCS control unit connector B (16P).
14. Connect pump motor relay connector terminal
