7. Check the resistance between the appropriate wheel sensor (+) and (-) circuit terminals (see table).

DTC | Appropriate Terminal
(+) Side | (-) Side
11 (Right-front) | No. 5: FRS (+) | No. 4: FRS (+)
13 (Left-front) | No. 7: FLS (+) | No. 6: FLS (+)
15 (Right-rear) | No. 2: RRS (+) | No. 1: RRS (+)
17 (Left-rear) | No. 9: RLS (+) | No. 8: RLS (+)

ABS CONTROL UNIT 31P CONNECTOR

Wire side of female terminals

Is the resistance between 450 - 2,000 ohms?

YES - Check for loose ABS control unit 31P connector. If necessary, substitute a known-good ABS modulator-control unit and recheck.

NO - Go to step 8.

8. Disconnect the harness 2P connector from the appropriate wheel sensor and check the resistance between the (+) and (-) terminals of the wheel sensor.

Is the resistance between 450 - 2,000 ohms?

YES - Repair open in the (+) or (-) circuit wire, or short between the (+) circuit wire and the (-) circuit wire between the ABS modulator-control unit and the wheel sensor.

NO - Replace the wheel sensor.

DTC 12, 14, 16, 18: Wheel Sensor Pulse Signal

NOTE: If the ABS indicator comes on for the reasons described below, the indicator goes off when you test-drive the vehicle at 31 mph (50 km/h).

- Only the drive wheel rotated
- The vehicle spun
- Electrical noise

1. Visually check for appropriate wheel sensor and pulsar installation and condition (see table).

   DTC | Appropriate Wheel Sensor
   12 | Right-front
   14 | Left-front
   16 | Right-rear
   18 | Left-rear

Are they installed correctly and not damaged?

YES - Go to step 2.

NO - Reinstall or replace the appropriate wheel sensor or pulsar.

2. Disconnect the ABS control unit 31P connector.
