Some 2005-2007 F-Super Duty vehicles may exhibit a speedometer and/or tachometer indicator issue. Symptoms may include intermittent, large inaccuracies, or jumping/bouncing/erratic pointers. ACTION Refer to the Service Procedure. SERVICE PROCEDURE 1. Verify there are no diagnostic trouble codes (DTCs). If there are DTCs present, follow the appropriate procedure in the Workshop Manual to clear the DTC and resolve the concern. 2. Confirm that the axle ratio and tire size are properly configured in the ABS module. 3. For a speedometer related concern, If no DTCs are present, the issue may be with any of the following components: • Cluster • ABS Module • ABS Speed Sensor • Vehicle Wiring • If the symptom is a continuous (non-intermittent) large inaccuracy, ensure that the axle ratio and tire size are properly configured in the ABS module. To identify the cluster as the root cause: 1. Monitor the vehicle speed sensor (VSS) PID in the powertrain control module (PCM), and the speedometer needle position while stopped. 2. If the speedometer displays 5 MPH (8 Km/h) or more, and the VSS PID indicates zero, replace the instrument cluster. 3. With an assistant observing the diagnostic tool, drive the vehicle at 20, 40, and 60 MPH (32, 64, and 97 Km/h) as indicated on the diagnostic tool, and record the value indicated by the speedometer. 4. If the speed indicated on the diagnostic tool versus speedometer readings vary by more than ± 5 MPH, (8 Km/h) replace the instrument cluster. ABS Module Concern To identify if the ABS Module is the root cause, refer to diagnostic procedures in the Workshop Manual. For any customer complaints of jumping/bouncing/erratic speedometers, a wiring concern may exist which is severe enough to interrupt the signal, but not severe enough to totally open/short the circuit.

TROUBLE SHOOTING FUEL/TEMPERATURE GAUGE NOT WORKING Check for blown fuse, faulty voltage limiter and faulty relay. Ensure sending unit connections are clean and tight. Test sending unit for correct operation. Tighten connections in instrument cluster. SPEEDOMETER NOT WORKING Ensure speedometer cable is properly connected and correctly routed. If speedometer pointer and/or odometer still do not work, replace speedometer as an assembly. TACHOMETER NOT WORKING Tachometer is serviced as an assembly. If wiring harness is okay, replace tachometer assembly. WARNING LIGHTS NOT WORKING Test for defective sending unit, burned-out bulb and broken printed circuit. Ensure all connections are clean and tight. TESTING BOOST PRESSURE GAUGE NOTE: Boost pressure gauge testing procedures for Galant are not available from manufacturer.

temperature variation between the left and right hand ducts. Typical concerns may include that the right side of the vehicle cools down but the left stays warm or the opposite. This condition is sometimes associated by the customer with a recent service visit for other non-related repairs. The codes, DTC B0361 or B0441, may be present but will not illuminate a telltale lamp. The HVAC controller unit and the TEMP door actuator motors rely on a feedback system that supplies the controller with count values in order to accurately adjust the air temperature. When battery power is interrupted to the HVAC controller, the current actuator position values are lost. When power is restored, the controller will perform a “sweep test” of the doors from full cold to full hot and record the end values for reference. Over time, the TEMP doors may develop some flexing when run to their extremes. This flexing allows the count values to run out of range (beyond 0-255) and results in DTC code B0361 or B0441 to set. A revised HVAC controller has been released with new programming that allows for a wider tolerance in the expected range of the TEMP door. Replace the controller using the procedure below: Important: On the 1997 Buick Century and Regal, additional steps are required. You will have to run a jumper wire to the new HVAC controller. Be sure to follow the additional 1997 model year steps below. 1. Disconnect the negative battery cable. Important: On the Buick Regal, the console must first be removed to access the HVAC controller. For Buick Century and Oldsmobile Intrigue, skip to Step 10. Apply the parking brake and block wheels. Shift the transmission to first gear. Remove the console trim plate and disconnect the electrical harness. Disconnect the cigarette lighter sockets. Remove the console storage box. Remove the console control plate and disconnect electrical harness for traction control and heated seats, if equipped. 8. Remove the console retaining bolts. 9. Remove the console from the vehicle. 10.Remove the HVAC trim panel, if equipped. 11.Remove the HVAC controller retaining bolts. 12.Disconnect the electrical harness. 13.Discard the HVAC controller.

NOTE: 1. Mazda vehicles are manufactured with tamper-proof speedometers and the mileage can not be altered or adjusted. 2. When a speedometer is replaced, the new speedometer will read zero (0). 3. This procedure is extremely important to accurately represent actual vehicle mileage. 4. The “Speedometer Replacement Label” referenced below is available through the Mazda Program Center for a limited time. Mazda Motor of America, Inc. is providing 1 sheet of 20 labels with this bulletin (see Illustration). REPLACEMENT PROCEDURE 1. Remove and replace the speedometer according to the workshop manual. 2. Complete the following information on the “Speedometer Replacement Label.” ^ Mileage before speedometer replacement ^ Date of replacement ^ Dealer code. 3. Attach the label to the driver’s side “B” pillar. 4. Complete the “Speedometer Replacement Record” in the Warranty Information Booklet as referenced.
