connected to the vehicle, the TBC module will enter a “sleep mode” but still continue to send a PWM voltage signal to the trailer tow connector every 4 seconds to detect when a trailer is connected. When the ignition key is in the RUN position and the module is in sleep mode, pressing a gain button or sliding the manual switch will cause the module to “wake up”. If a trailer is not connected to the vehicle, the display should prove out for 3 seconds, then the trailer icon should illuminate red and the IC message center should display TRAILER DISCONNECTED or CHECK TRAILER. If a trailer is connected to the vehicle, the display should prove out for 3 seconds and then the trailer icon should illuminate green. Inspection and Verification NOTE: A trailer brake emulator tool is available to verify that the TBC module and vehicle wiring are functioning correctly. 1. Verify the TBC system is correctly installed by checking that the vehicle is equipped with a brake pressure transducer on the master cylinder. If the brake pressure transducer is not present, then the TBC system has been erroneously installed. 2. Verify the customer concern. 3. NOTE: The TBC does not function with electric-over-hydraulic or surge trailer brake types. Verify that the trailer brakes are electric-actuated drum type brakes. 4. Verify the stoplamps operate correctly by applying and releasing the brake pedal with the ignition switch in the OFF position and the trailer disconnected. If the stoplamps do not operate correctly, refer to Section 417-01 . If the stoplamps operate correctly, proceed to the next step. 5. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Chart 6. If the cause is not visually evident, connect the scan tool to the data link connector (DLC) and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle: * check that the program card is correctly installed. * check the connections to the vehicle. * check the ignition switch position. 7. If the scan tool still does not communicate with the vehicle, refer to the scan tool operating manual. 8. Carry out the scan tool data link test. If the scan tool responds with: * CAN, ISO, or UBP circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 . * No response/not equipped for the TBC, GO to Pinpoint Test A . * System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the TBC and the antilock brake system (ABS) module. 9. If the DTCs retrieved are related to the concern, go to the Trailer Brake Control (TBC) module Diagnostic Trouble Code (DTC) Chart or Anti-Lock Brake System (ABS) Module Diagnostic Trouble Code (DTC) Chart to continue diagnosis. 10. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue diagnosis. NOTE: Always retrieve the continuous DTCs after running the self-test.

2003 Ford Truck Expedition Suspension – Air Suspension Height Sensor Linkage Loose Service Procedure

download
ISSUE Some 2003-2006 Expedition and Navigator vehicles equipped with an air suspension may exhibit an air suspension height sensor linkage arm disengaging from the suspension ball stud or height sensor rotating arm. This concern typically occurs with the rear sensor (Figure 1) but may occur with the front sensors as well. If this occurs, the symptom will typically be the vehicle leaning to one side, the vehicle sitting too low/high, a harsh ride, and/or an inoperative air suspension. In addition, this concern may result in diagnostic trouble code (DTC) C1725 (air suspension front pneumatic failure) or C1726 (air suspension rear pneumatic failure). ACTION When a linkage arm becomes disengaged, do not re-attach the arm and do not replace the sensor unless broken. Instead, install a revised linkage arm on all three (3) sensor assemblies, even if they have not detached from the ball stud. 1. Replace linkage arms on all three (3) sensor assemblies following Workshop Manual (WSM), Section 204-05. 2. Discard the old linkage arms. NOTE IF THE SENSOR ASSEMBLY NEEDS TO BE REPLACED FOR ANY DAMAGE/FAILURE OTHER THAN THE ONE DESCRIBED IN THIS TSB, THE REPLACEMENT ASSEMBLY IS SUPPLIED WITH A NEW STYLE LINKAGE ARM, SO THERE IS NO NEED TO ORDER ADDITIONAL LINKAGES FOR THE SERVICE REPAIR. WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage OPERATION DESCRIPTION TIME 061510A 2003-2006 0.4 Hr. Expedition/Navigator: Replace The Three Linkage Arms, Includes Time To Check Diagnostic Trouble Codes (Do Not Use With 5300A, 5300A7, 5300A8) DEALER CODING CONDITION BASIC PART NO. CODE 5A967
