Test D: Abs Sensor Circuit Failure

NOTE: This test is associated with DTCs C1145 (RF), C1155 (LF), C1165 (RR), C1175 (LR).
  1. Turn ignition off. Connect Breakout Box. Measure voltage between Breakout Box pins (as shown in chart), depending on DTC retrieved. See appropriate ABS SENSOR CIRCUIT TEST. If voltage is present, repair circuit(s) in question. Restore vehicle, clear DTCs and recheck system operation. If voltage is not present, go to next step.
    ABS SENSOR CIRCUIT TEST - INPUT CIRCUIT FAILURE (2000)

    DTC - Wheel Circuit Breakout Box Pin No. (Wire Color)
    C1145 - RF 18 (YEL/BLK) To 3 (YEL/RED)
    C1155 - LF 11 (TAN/BLK) To 4 (TAN/ORG)
    C1165 - RR 1 (PK/BLK) To 17 (RED/PK)
    C1175 - LR 2 (LT. GRN/BLK) To 10 (LT. GRN/RED)
    ABS SENSOR CIRCUIT TEST - INPUT CIRCUIT FAILURE (2001)

    DTC - Wheel Circuit Breakout Box Pin No. (Wire Color)
    C1145 - RF 5 (YEL/BLK) To 4 (YEL/RED)
    C1155 - LF 21 (TAN/BLK) To 20 (TAN/ORG)
    C1165 - RR 3 (PK/BLK) To 1 (RED/PK)
    C1175 - LR 23 (LT. GRN/BLK) To 22 (LT. GRN/RED)
  2. Turn ignition off. Connect Breakout Box. Measure resistance between Breakout Box pins (as shown in chart). See appropriate ABS SENSOR CIRCUIT TEST table. If resistance of suspect circuit is 800-1400 ohms, go to step 4)  . If resistance is not 800-144 ohms, go to next step.
  3. Disconnect suspect ABS sensor. Measure resistance between 2 pins on component side of sensor. If resistance is 800-1400 ohms, repair circuit in question. Restore vehicle, clear DTCs and recheck system operation. If resistance is not 800-1400 ohms, install new ABS sensor. Restore vehicle, clear DTCs and recheck system operation.
  4. Measure resistance between Breakout Box pin and ground (as shown in chart): See appropriate RESISTANCE CHECK TERMINAL IDENTIFICATION table. If resistance is greater than 10 k/ohms, install new ABCM. Restore vehicle, clear DTCs and recheck system operation. If resistance is not greater than 10 k/ohms go the next step.
    RESISTANCE CHECK TERMINAL IDENTIFICATION (2000)

    DTC - Wheel Circuit Breakout Box Pin No. (Wire Color)
    C1145 - RF 3 (YEL/RED)
    C1155 - LF 4 (TAN/ORG)
    C1165 - RR 17 (RED/PK)
    C1175 - LR 10 (LT. GRN/RED)
    RESISTANCE CHECK TERMINAL IDENTIFICATION (2001)

    DTC - Wheel Circuit Breakout Box Pin No. (Wire Color)
    C1145 - RF 4 (YEL/RED)
    C1155 - LF 20 (TAN/ORG)
    C1165 - RR 1 (RED/PK)
    C1175 - LR 22 (LT. GRN/RED)
  5. Measure resistance between suspect ABS sensor pin and ground. If resistance is more than 10 k/ohms, repair circuit(s) in question. Restore vehicle, clear DTCs and recheck system operation. If resistance is not more than 10 k/ohms, install new ABS sensor. Restore vehicle, clear DTCs and recheck system operation.
