Pinpoint Test E : C1222, C1296, C1297, C1298, C1299

WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: If the ignition is set to ON when one or more wheel speed sensors are disconnected, the ABS module disables the output to that sensor. Make sure all test connectors are made at the sensor before setting the ignition to ON.

  1. E1 CHECK THE ABS MODULE DTCs

    • Using a diagnostic scan tool, carry out the ABS module self-test.

    Is DTC C1145, C1155, C1165 or C1175 also present? 

    Yes  GO to Pinpoint Test D .
    No  GO to  E2.

  2. E2 MONITOR THE WHEEL SPEED SENSOR PIDs

    • Ignition ON.
    • Using a diagnostic scan tool, view the ABS module wheel speed sensor PIDs.
    • While driving the vehicle at the speed at which the concern occurred, monitor the following PIDs :
      • Left Front Wheel Speed Sensor (LF_WSPD)
      • Right Front Wheel Speed Sensor (RF_WSPD)
      • Left Rear Wheel Speed Sensor (LR_WSPD)
      • Right Rear Wheel Speed Sensor (RR_WSPD)

    Are the wheel speed sensor PIDs consistent with the vehicle speed and each other? 

    Yes  CLEAR the DTCs. DRIVE the vehicle. REPEAT the self-test. RETRIEVE and RECORD any ABS module DTCs. If DTC C1296, C1297, C1298 or C1299 returns, GO to  E11. If DTC C1222 returns, GO to  E10.For all other ABS module DTCs, GO to the DTC Chart: ABS Module . If no DTCs return, INSPECT the ABS module and wheel speed sensor connectors for corrosion, pushed-out pins, or damaged pins and REPAIR as necessary. If all connectors are OK, GO to  E7.
    No  If the Rotunda Active Wheel Speed Sensor Tester is not  available, GO to E5  . If the Rotunda Active Wheel Speed Sensor Tester is  available, GO to E3  .

  3. E3 CHECK THE ABS MODULE OUTPUT USING THE ROTUNDA ACTIVE WHEEL SPEED SENSOR TESTER

    • Ignition OFF.
    • Disconnect the suspect wheel speed sensor electrical connector.
    • Connect the Rotunda Active Wheel Speed Sensor Tester to the wheel speed sensor connectors.
    • Select the correct system polarity on the Rotunda Active Wheel Speed Sensor Tester and turn the power switch to the ON position.
    • Ignition ON.

    Is the module output LED illuminated? 

    Yes  GO to  E4.
    No  GO to  E6.

  4. E4 CHECK THE WHEEL SPEED SENSOR OUTPUT WITH THE ROTUNDA ACTIVE WHEEL SPEED SENSOR TESTER

    • While monitoring the Rotunda Active Wheel Speed Sensor Tester, slowly spin the suspect wheel.

    Do the sensor output LEDs illuminate and flash and is the current overload LED not illuminated? 

    Yes  INSPECT the wheel speed sensor encoder for damage and looseness. INSTALL new components as necessary. If the encoder is OK, the concern may have been caused by a loose or corroded connector.
    No  If the current level LED is not  illuminated and the sensor output LEDs do not  illuminate or if the current level LED is illuminated red, INSTALL a new wheel speed sensor. REFER to Wheel Speed Sensor - Front  or Wheel Speed Sensor - Rear . If the current level LED is not  illuminated and the sensor output LEDs illuminate green but do not  flash, INSPECT the wheel speed sensor encoder and INSTALL new if necessary. If the encoder is OK, INSTALL a new wheel speed sensor. REFER to Wheel Speed Sensor - Front  or Wheel Speed Sensor - Rear .

  5. E5 CHECK THE ABS MODULE OUTPUT

    NOTE: Make sure all test connections are made at the wheel speed sensor before the ignition is set to ON.

    NOTE: Use a meter with a min-max feature or recording capabilities to obtain accurate measurements. The ABS module disables the voltage output immediately if the wheel speed sensor is not present.

    • Ignition OFF.
    • Disconnect the suspect wheel speed sensor electrical connector.
    • For DTC C1145  , connect the meter as follows:
