11. Test the brake booster See: Brakes and Traction Control/Power Brake Assist/Vacuum Brake Booster/Testing and Inspection.
12. Start the engine, then press the brake pedal with about 314 N (32 kgf, 70.6 lbf) pressure.
13. Check the right front brake fluid pressure voltage (RF BRAKE P) with the HDS.
Is there about 2.5 V?
YES -
The right front brake fluid pressure signal is OK, check for loose or poor connections. If OK, update the ACC unit See: Cruise Control/Testing and
Inspection/Programming and Relearning, then recheck. If the ACC unit was already updated, replace the ACC unit See: Cruise Control/Cruise
Control Module/Service and Repair.?
NO -
Go to step 14.
14. Turn the ignition switch to LOCK (0).
15. Disconnect the ACC unit 20P connector.
16. Measure the resistance between ACC unit 20P connector terminal No. 5 and body ground. There should be an open circuit or at least 1
MOhms.
Is the resistance as specified?
YES -
Go to step 17.
NO -
Repair a short to ground in the wire between the ACC unit and the right front brake fluid pressure sensor.?
17. Disconnect the right front brake fluid pressure sensor 3P connector.
18. Connect right front brake fluid pressure sensor 3P connector terminal No. 2 to body ground with a jumper wire.
19. Measure the resistance between ACC unit 20P connector terminal No. 5 and body ground. There should be less than 1.0 Ohms.
