Is the voltage as specified?
YES -
Go to step 19.
NO -
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.?
19. Turn the ignition switch to LOCK (0).
20. Disconnect the ACC unit 20P connector.
21. Measure the resistance between ACC unit 20P connector terminal No. 14 and body ground. There should be an open circuit or at least 1
MOhms.
Is the resistance as specified?
YES -
Go to step 22.
NO -
Repair a short to ground in the wire between the ACC unit and the left front brake fluid pressure sensor.?
22. Disconnect the left front brake fluid pressure sensor 3P connector.
23. Connect left front brake fluid pressure sensor 3P connector terminal No. 3 to body ground with a jumper wire.
24. Measure the resistance between ACC unit 20P connector terminal No. 14 and body ground. There should be less than 1.0 Ohms.
