Instrument Cluster Test 12E - Brake Warning Light
NOTE:
Perform INSTRUMENT CLUSTER TEST 12A before proceeding with this test. For connector terminal identification and wiring diagrams, see CONNECTOR IDENTIFICATION section in this article. Perform VERIFICATION TEST VER-1A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Disconnect brake fluid level switch 2-pin connector at master cylinder and ensure connector is clean and not damaged. Connect a jumper wire between brake fluid level switch connector terminals. Turn ignition on with engine off. If brake warning light does not illuminate, disconnect jumper wire and go to next step. If brake warning light comes on, replace brake fluid level switch.
- Connect a jumper wire between brake fluid level switch connector terminal No. 2 (Gray/Dark Blue wire) and ground. If brake warning light comes on, repair open in Black wire. If parking brake light does not illuminate and testing was because light did not illuminate when brake fluid reservoir was empty, replace low brake fluid switch. If parking brake light does not illuminate and brake fluid level was okay, system is operating properly.
