Line Pressure Check Procedure Tools Required Important: Before performing a line pressure check, verify that the pressure control (PC) solenoid valve is receiving the correct electrical signal from the PCM. Caution: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result it the vehicle moves unexpectedly. J 21867Universal Pressure Gauge Set 1. Install a Scan Tool. 2. Start the engine and set the parking brake. 3. Check for a stored Diagnostic Trouble Code (DTC). 4. Repair the vehicle, if necessary. 5. Check the fluid level. Refer to the Transmission Fluid Checking Procedure. 6. Check the manual linkage for proper adjustment. 7. Turn the engine OFF. Remove the oil pressure test hole plug and install the J 21867. 8. Put the gear selector in PARK range and set the parking brake. 9. Start the engine and allow the engine to warm up at idle Notice: Total test running time should not be longer than two minutes, or else transmission damage could occur. Notice: Refer to Fastener Notice in Cautions and Notices. Parts Information 10. Access the PC solenoid valve control test on the Scan Tool. Zoom Sized for Print 11. Increase the PC solenoid as shown actual current from 0.0 to 1.0 amps in 0.1 amp increments. Allow the pressure to stabilize for five seconds after each pressure change. Read the corresponding line pressure on the J 21867. 12. Refer to the Line Pressure specification table. Compare the data to the table. 13. If pressure readings differ greatly from the table, refer to Incorrect Line Pressure. 14. Remove the J 21867. 15. Apply sealant, P/N 12345382 (in Canada, P/N 10953489), to the oil pressure test hole plug. 16. Install the oil pressure test hole plug.

INITIAL VISUAL INSPECTION 1. Place the vehicle on a suitable lift. 2. Visually inspect the parking brake cable installation, parking brake caliper levers and general condition of the brakes. • Ensure the caliper levers are returning fully to their stops. • Confirm the cable routing is correct • Confirm that the cable is securely fixed at all abutment points and is free to move within the C-clip. • Where cable routing goes over the top of the stabilizer bar drop links, confirm that the stabilizer bar rubber deflector blocks are fitted, and that the brake cables have not been getting trapped behind the stabilizer bar drop links (look for tell-tale marks on the links and/or cables). NOTE: Global Technical Reference (GTR) lookup sequence is as follows: GTR Home > NAS > Model > Service Information > Model Year > Workshop Manual > 2: Chassis — Section 206: Brake System NOTE: Refer to the correct section by reference to VIN and based on whether the vehicle is fitted with high performance brakes or not. 3. Rectify any obvious faults. 4. If no obvious faults are found or further guidance is needed to rectify faults, please proceed to the next stage of this bulletin. Refer to GTR Sections 206-05 (parking Brake and Actuation) and GTR Section 206-04 (Rear Disc Brake). 5. If any faults were found and rectified, it will be necessary to re-calibrate the parking brake after rectification. See ‘Parking Brake Calibration’ procedure. PREPARE THE PARKING BRAKE FOR DETAILED INSPECTION CAUTION: Jaguar IDS DVD 111 or later and Midtronics PSC-550 Vehicle Power Supply must be connected to the vehicle battery during diagnosis. 1. Install the Midtronics PSC-550 Vehicle Power Supply to the vehicle. 2. Connect the IDS to the vehicle and begin a new diagnostic session by entering the correct VIN for the current vehicle. 3. Follow the IDS prompts to read the vehicle configuration. 4. Select ‘YES’ when prompted ‘Do you wish to read diagnostic trouble codes?’. 5. Follow all on-screen instructions to complete this task. 6. Select ‘Vehicle Configuration’ tab when the ‘Content Model’ is displayed. 7. Select ‘Electronic Parking Brake’. 8. Select ‘Release to Service Position’ (S-TYPE/XJ) or ‘Parking Brake Unjam Procedure’(XK) ‘. CAUTION: When using the special service tool, take care to operate in the ‘release’ direction. Actuator motor damage may result if the tool is operated in the ‘apply’ direction for any length of time). 9. If the parking brake will not release using IDS, use the special service tool to fully release the parking brake. Refer to GTR Section ‘Parking Brake Cable Tension Release’ (in Section 206-05) for details of using the special service tool.

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.
