Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the steering angle sensor.
  2. Test for less than 10 Ω between the low reference circuit terminal 6 and ground.
    • If greater than specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the electronic brake control module.
  3. Ignition ON, test for B+ between the 12 V reference terminal 1 and ground.
    • If less than the specified range, test the 12 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the electronic brake control module.
  4. Disconnect the harness connector at the electronic brake control module.
  5. Ignition ON, test for less than 1 V between the signal circuit terminals listed below and ground.
    • Can HI Serial Data Terminal 18
    • Can Lo Serial Data Terminal 19
    • If greater than the specified value, test the signal circuit for a short to voltage.
  6. Ignition OFF, test for infinite resistance between the signal circuit terminals listed below and ground.
    • Can HI Serial Data Terminal 18
    • Can Lo Serial Data Terminal 19
    • If not the specified value, test the signal circuit for a short to ground.
  7. Test for less than 2 Ω between the signal circuit terminal 19 at the electronic brake control module harness connector and the signal circuit terminal 4 at the steering angle sensor.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  8. Test for less than 2 Ω between the signal circuit terminal 18 at the electronic brake control module harness connector and the signal circuit terminal 3 at the steering angle sensor.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  9. If all circuits test normal, replace the steering angle sensor.
