Diagnosis & Testing

Print

  1. Perform the following preliminary inspections:
    1. Ensure that the battery is fully charged.
    2.  
    3. Ensure that the battery cables are clean and tight.
    4.  
    5. Inspect for any open fuses
    6.  
    7. Inspect the easily accessible systems or the visible system components for obvious damage or conditions that could cause the symptom.
    8.  
    9. Ensure that the grounds are clean, tight, and in the correct location.
    10.  
    11. Inspect for aftermarket devices that could affect the operation of the system.
    12.

The Saturn ABS Electronic Brake Control Module (EBCM) is similar in many ways to the Powertrain Control Module. It is an electronic controller of the ABS system which is capable of monitoring system function through the system circuits. It will constantly monitor the output from its various sensors to determine if a sensor or circuit is operating properly.

When the EBCM detects a problem, it will set a trouble code or flag. If the fault is serious enough to affect braking, the EBCM will illuminate the red ANTILOCK warning lamp. Whenever the lamp is lit, the ABS system is disabled and will NOT operate, but normal hydraulic braking will exist. In this way, the system is prevented from ever disabling or adversely affecting the vehicle's hydraulic brakes due to a partial or complete ABS failure.

As with the PCM system, trouble codes and flags are stored in both general information and malfunction history circuits of the control module. General information is cleared each time the ignition switch is turned OFF , but codes will reset when the ignition is turned ON again and the malfunction is still present. Data will remain in malfunction history for a series of 100 ignition cycles after a fault disappears, unless a scan tool is used to clear the memory earlier. Disconnecting the power will have no affect on data stored in the EBCM malfunction history circuits.

A scan tool MUST be used for fault code diagnosis and troubleshooting on the ABS EBCM.
