Test Procedure

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
NOTE: The yaw rate sensor and accelerometer are integral to the sensor cluster.

The sensor cluster is not serviceable and must be installed as an assembly.

  1. H1 - CARRY OUT THE RECALIBRATION PROCEDURE

    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Clear DTCs.
    • Carry out the yaw rate sensor recalibration procedure using the diagnostic tool.
    • Enter the following diagnostic mode on the diagnostic tool: Retrieve DTCs.
    • Are any DTCs retrieved or does the recalibration procedure indicate a fault? 
      1. Yes  : GO to H2.
      2. No  : The ABS system is operating correctly.

  2. H2 - CHECK THE ABS MODULE YAW RATE PID

    • Monitor the ABS module yaw rate PID.
    • Is the ABS module yaw rate PID value between 479 and 545? 
      1. Yes  : INSTALL a new yaw rate sensor. REFER to YAW RATE SENSOR  in this section. CLEAR DTCs. RECALIBRATE the ABS module. FOLLOW the diagnostic tool directions for the calibration procedure. REFER to MODULE COMMUNICATIONS NETWORK . REPEAT the self-test.
      2. No  : GO to H3.

  3. H3 - RE-VERIFY THE ABS MODULE YAW RATE PID

    • Monitor the ABS module yaw rate PID.
    • Is the ABS module yaw rate PID value between 479 and 545? 
      1. Yes  : CHECK the ABS module connector for loose or corroded pins. CLEAR the DTC. REPEAT the self-test.
      2. No  : GO to H4.

  4. H4 - CHECK THE VOLTAGE FROM THE ABS MODULE

    • Connect: ABS Module C135.
    • Key in ON position.
    • Measure the voltage between yaw rate sensor C3073-1, circuit 7-CF67 (YE/RD), harness side, and yaw rate sensor C3073-5, circuit 9-CF67 (BN/RD), harness side.

    • Is the voltage approximately 10 volts? 
      1. Yes  : INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE  in this section. CLEAR the DTC. REPEAT the self-test.
      2. No  : GO to H5.

  5. H5 - CHECK THE YAW RATE SENSOR CIRCUITRY FOR AN OPEN

    • Measure the resistance between ABS module C135 pins, harness side, and yaw rate sensor C3073 pins, harness side as follows:

    • Is the resistance less than 5 ohms? 
      1. Yes  : GO to H6.
      2. No  : REPAIR the circuit in question. CLEAR the DTC. RECALIBRATE the ABS module. FOLLOW the diagnostic tool directions for the calibration procedure. REFER to MODULE COMMUNICATIONS NETWORK . REPEAT the self-test.

  6. H6 - CHECK THE YAW RATE SENSOR CIRCUITRY FOR A SHORT TO POWER

    • Key in OFF position.
    • Disconnect: ABS Module C135.
    • Disconnect: Yaw Rate Sensor C3073.
    • Key in ON position.
    • Measure the voltage between ABS module C135 pins, harness side, and ground as follows:

    • Is voltage present? 
      1. Yes  : REPAIR the circuit in question. CLEAR the DTC. RECALIBRATE the ABS module. FOLLOW the diagnostic tool directions for the calibration procedure. REFER to MODULE COMMUNICATIONS NETWORK . REPEAT the self-test.
      2. No  : GO to H7.

  7. H7 - CHECK THE YAW RATE SENSOR CIRCUITRY FOR A SHORT TO GROUND

    • Key in OFF position.
    • Measure the resistance between the yaw rate sensor C3073 pins, harness side, and ground as follows:
      YAW RATE SENSOR C3073 PINS CHART
