K9 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) 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 immediately disables the voltage output if the wheel speed sensor is not present.
Ignition OFF. Connect ABS module C135. Connect the meter to the suspect wheel speed sensor electrical connector, harness side. Set the meter to measure DC voltage. Set the meter range to greater than 15 volts. Enable the min-max or recording feature on the meter. Ignition ON. For the LH front wheel speed sensor, measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
