Brake Warning Indicator: Testing and Inspection
BRAKE INDICATOR
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting
any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further
diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result
in accidental airbag deployment.
The hard wired park brake switch input to the EMIC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate
wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and
retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the Controller Antilock Brake (CAB), the Controller
Area Network (CAN) data bus, or the electronic message inputs also used by the EMIC to provide brake indicator operation. The most reliable, efficient,
and accurate means to diagnose the EMIC, the CAB, the CAN data bus or the electronic communication related to brake indicator operation requires the
use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
