APPLIED VEHICLES: All Infiniti SERVICE INFORMATION • This bulletin is to assist you in responding to customer questions about brake operation, and provides diagnostic and repair information for each item listed, if any should occur. • Most brake issues fall into the following categories: a. Brake Noise: A squeak, squeal, clunk, or groan that occurs when the brakes are applied or released. b. Brake Judder: A vibration that can be felt in the vehicle, steering wheel, or brake pedal when the brakes are applied. c. Pedal Feel: The effort needed to operate the brakes is too high or too low. SERVICE PROCEDURE 1. Verify the condition by road testing the vehicle with the customer. 2. Determine the specific brake issue based on the description in the Service Information above. 3. Follow the appropriate repair procedure(s), listed on the following pages, for your specific issue. BRAKE NOISE • Brakes can make a range of noises when applied or released. Some noises are normal and no repair action should be taken. • Use the following descriptions to identify the specific type of brake noise and the appropriate repair: Squeak noise when the brakes are cold: • Usually occurs during the first few stops in the morning. • This is a normal condition. No service action is necessary Squeak noise with the brakes at normal operating temperatures: • Refer to technical bulletins specific to the model of vehicle regarding this issue. • If there are no bulletins for the car you are working on, install OE type pads using the information listed under Brake Service on page 5 of this bulletin and the appropriate Service Manual procedures. Notes about brake pads and brake noise: Original Equipment (OE) brake pads are installed on all current Infiniti vehicles at the factory. • The OE pads use a Non-asbestos Organic (NAO) compound. The NAO material provides state of the art resistance to squeal noise. • These pads are available as service parts and must be used if replacing brake pads under the terms of the Infiniti new car warranty.

NOTE: Before performing diagnostic procedure, follow testing procedure. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM. DTC Confirmation Test Malfunction is detected when an excessively high or low voltage is sent to ECM from Intake Valve Timing Control (IVTC) position sensor. Possible causes are: IVTC position sensor circuit open or shorted. Faulty IVTC position sensor. Faulty Crankshaft Position (CKP) sensor (REF). Faulty CKP sensor (POS). Faulty Camshaft Position (CMP) sensor. To set DTC, turn ignition on and select DATA MONITOR with scan tool. Slightly increase engine speed and hold for at least 10 seconds. If first trip DTC is detected, go to PROCEDURE . Reference Values For ECM Terminals and Reference Values, see Fig. 39 . Procedure 1. Turn ignition off. Loosen and retighten engine ground bolts. See Fig. 5 . Disconnect appropriate IVTC position sensor harness connector. See Fig. 40 or Fig. 41 . Turn ignition on. Measure voltage between ground and IVTC position sensor harness connector terminal No. 3 (Black/White wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open or short circuit and retest system. See WIRING DIAGRAMS article. 2. Turn ignition off. Check continuity between engine ground and IVTC position sensor harness connector terminal No. 1 (Black wire). Also check circuit for short to voltage. Repair circuit as necessary and retest system. If ground circuit is okay, go to next step. 3. Disconnect ECM harness connector. See Fig. 3 . Check continuity of Yellow/Green wire between right IVTC position sensor harness connector terminal No. 2 and ECM harness connector terminal No. 79, or
