Test 9A - No Response From Anti-Lock Brake Controller
NOTE:
For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAMS
. Perform TEST VER-2A - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Turn ignition off. Disconnect anti-lock brake controller connector. Anti-lock brake controller is located under left front of vehicle, behind transaxle. Turn ignition on. Using an external voltmeter, measure voltage on anti-lock brake controller connector terminal No. 23 (White/Pink wire). If voltage is 10 volts or less, repair open White/Pink wire. If voltage is more than 10 volts, go to next step.
- Measure voltage on anti-lock brake controller connector terminal No. 25 (Red/Dark Green wire). If voltage is 10 volts or less, repair open Red/Dark Green wire. If voltage is more than 10 volts, go to next step.
- Using an external ohmmeter, measure resistance between anti-lock brake controller connector terminal No. 24 (Black wire) and ground. If resistance is 10 ohms or more, repair open Black wire. If resistance is less than 10 ohms, go to next step.
- Connect jumper wire between ground and anti-lock brake controller connector, terminal No. 20 (Violet/Brown wire). Turn ignition on. Using scan tool, select BODY, BODY COMPUTER, then SYSTEM TEST. Perform CCD BUS test. If scan tool does not display BUS SHORT TO GROUND, repair open Violet/Brown wire. If scan tool displays BUS SHORT TO GROUND, go to next step.
- Move jumper wire to anti-lock brake controller connector, terminal No. 19 (White/Tan wire). Perform CCD BUS test. If scan tool does not display BUS SHORT TO GROUND, repair open White/Tan wire. If scan tool displays BUS SHORT TO GROUND, replace anti-lock brake controller.
