Diagnosis of the ABS system consists of 3 general steps, performed in order:
- The visual or preliminary inspection, including inspection of the basic
brake system, is always required before any other steps are taken.
- Initial diagnosis is then made by a careful analysis of the ANTI-LOCK Warning
Lamp display during start-up and operation. The warning lamp troubleshooting
chart will direct the use of further charts and detailed testing based on
initial findings.
WARNING
Make sure the ignition is turned
OFF before the scan tool is installed!
- The ABS system may be further checked with the DRB-III, MUT-II or equivalent
diagnostic scan tool, provided the correct cartridges are used. The scan tool,
will allow various components of the system to be operated for testing purposes.
Connect the scan tool according to instructions furnished with the tool. The
system will enter diagnostic mode and prompt the operator through the assorted
system checks and tests.
