CIRCUIT DESCRIPTION A thermistor built into the engine coolant temperature sensor changes the resistance value according to the
engine coolant temperature. The structure of the sensor and connection to the ECM is the same as in the intake air temp. circuit malfunction shown on page DI-26 .
If the ECM detects the DTC P0115, it operates the fail-safe function in which the engine coolant temp. is assumed to be 80°C (176°F).

This bulletin is to provide information about some brake noise characteristics heard during normal operation. Please utilize this bulletin when explaining brake noises to eliminate concerns and reduce unnecessary component replacement. It should be considered normal for the brake system to have some noise during normal operation. This is most common with disk brake systems and will happen from time to time. It is caused by friction when the pads are stopping the brake disc from rotating. The definition of brake noise can be different case by case, driver to driver and situation to situation. Noise can be defined as an unpleasant sound and the severity is usually affected by the sensitivity of the

B D Replace engine oil filter. Torque filter: 16 lb-ft. D Inspect front and rear brakes. • Check pads and discs for wear (measure thickness with the calipers installed), and visually inspect the pads and discs for cracks, grooves, etc. – Front pad thickness: Std 9.5–10.5 mm, Limit 1.6 mm. – Front disc thickness: Std 20.9–21.8 mm, Limit 19.0 mm. – Drum I.D. Std. 199.9–200 mm, Limit 201 mm. • Visually check calipers for leaks. • Remove the rear brake drums, and visually check brake lining for cracking, glazing, contamination; and measure for wear. Std. lining thickness 4.0 mm, Limit 2.0 mm. • Visually check wheel cylinders for leaks. D Check parking brake adjustment. Should be fully applied within 6 to 7 clicks. D Visually inspect tie-rod ends, steering gearbox, and rack
boots for impact damage and cracked or torn rubber boots. • Turn the steering wheel back and forth to check steering
linkage for looseness. • Visually check fluid lines for damage and leaks. D Visually inspect suspension components for damage. Visually
check ball joint boots for deterioration and damage. D Visually inspect driveshaft boots for cracks, and check boot
bands for tightness. D Visually inspect brake hoses and lines (including ABS). Visually check the master cylinder, proportioning control
valve, and ABS modulator for damage and leakage. D Visually check all fluid levels, condition of fluids (discoloration, contamination), and visually check for leaks. If needed, add trans fluid (use Honda ATF-Z1 or Honda MTF), coolant (use Honda All Season Antifreeze/Coolant Type 2), brake fluid (use Honda DOT 3 Brake Fluid), P/S fluid (use Honda Power Steering Fluid), and windshield
washer fluid. D #Visually inspect exhaust system (catalytic converter heat shield, exhaust pipe, and muffler) for damage and leaks. D #Visually inspect fuel lines and connections for looseness, cracks, deterioration, and leaks. D Replace dust and pollen filter if the vehicle is driven in urban areas with high concentrations of soot, or whenever airflow is less than normal. A

Cause This condition may be caused by a damaged forward sprag assembly (642). Correction When inspecting the sprag, it is important to test the sprag for proper operation by holding the outer race (644) with one hand while rotating the input sun gear (640) with the other hand. The sun gear should rotate only in the counterclockwise direction with the input sun gear facing upward. If the sprag rotates in both directions or will not rotate in either direction, the sprag elements should be inspected by removing one of the sprag reserved. retaining rings (643).

CONDITIONS E1 CHECK THE IGNITION STATES — MONITOR THE GEM/CTM PID IGN_GEM DETAILS/RESULTS/ACTIONS Scan Tool E2 RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCS) NOTE: If the vehicle is equipped with a manual transmission, depress the clutch while turning the ignition switch to start. Monitor the GEM/CTM PID IGN_GEM while turning the ignition switch through the START, RUN, OFF and ACC positions. Do the PID values agree with the ignition switch positions? Yes GO to E2. No REFER to Section 417-02. Retrieve and document continuous DTCs. Clear Continuous DTCs GEM/CTM Wiper/Washer Self-Test Are any DTCs recorded? Yes If DTC B1450, GO to E3 . If DTC B1453, GO to E3 . If DTC B1458, GO to E9 . If DTC B1460, GO to E9 . If DTC B1342, REPLACE the GEM/CTM; REFER to Section 419-10. CLEAR the DTCs. TEST the system for normal operation. No GO to E3. E3 CHECK THE WASHER SWITCH OUTPUTS — MONITOR THE GEM/CTM PID WPMODE Monitor the GEM/CTM PID WPMODE while turning the wiper switch through all the switch positions. E4 CHECK THE WASHER SWITCH — MONITOR THE GEM/CTM PID WASH_SW Does the GEM/CTM PID WPMODE agree with all the wiper switch positions? Yes GO to E4. No GO to E6. Monitor the GEM/CTM PID WASH_SW.
