Automatic Transmission/transaxle External Controls: Diagnosis Jaguar XKR II

Inspection and Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity. Visual Inspection Mechanical Electrical Check for correct gear selector lever cable adjustment. See «Selector Lever Cable Adjustment»(ref-312593-S11099770522009041400000) . Visibly damaged or worn components Loose or missing fasteners Fuse(s) Loose or corroded electrical connector(s)
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident, verify the symptom and refer to the manufacturer approved diagnostic system, or pinpoint tests below.

Pinpoint Test : GEAR SELECTOR LEVER ASSEMBLY CIRCUIT CHECKS

1. CHECK FOR IGNITION SUPPLY TO THE GEAR SELECTOR LEVER ASSEMBLY Disconnect the gear selector lever assembly electrical connector IP027. Set the ignition status to ON, engine OFF. Measure the voltage at IP027 Pin 1. Is the voltage greater than 10 Volts? YES: Go to step 2 . NO: Repair the electrical circuit between the gear selector lever assembly electrical connector IP027 Pin 1 and the Central Junction Box (CJB). For additional information, refer to the appropriate system wiring diagrams article. TEST the system for normal operation.
2. CHECK THE GROUND SUPPLY TO THE GEAR SELECTOR LEVER ASSEMBLY Set the ignition status to OFF. Measure the resistance between the gear selector lever assembly electrical connector IP027 Pin 2 and GROUND. Is the resistance less than 5 Ohms? YES: Go to step 3 . NO: Repair the circuit between the gear selector lever assembly electrical connector IP027 Pin 2 and GROUND. For additional information, refer to the appropriate system wiring diagrams article. TEST the system for normal operation.
3. CHECK FOR IGNITION SUPPLY TO THE PARK POSITION SWITCH Set the ignition status to ON, engine OFF Measure the voltage at IP027 Pin 4. Is the voltage greater than 10 Volts? YES: No fault has been identified with the gear selector lever assembly circuits. Check all connections for damaged and corroded pins. Check CAN network using manufacturer approved diagnostic system. TEST the system for normal operation. NO: Repair the electrical circuit between the gear selector lever assembly electrical connector IP027 Pin 4 and the Central Junction Box (CJB). For additional information, refer to the appropriate system wiring diagrams article. TEST the system for normal operation.

Pinpoint Test : GEAR SELECTOR PADDLE SWITCH TESTS

1. GEAR SELECTOR PADDLE SWITCH TESTS Check steering wheel speed control switches are functioning correctly. Are the steering wheel speed control switches functioning correctly? YES: Refer to the appropriate system wiring diagrams article and test circuit between gear selector paddle switches and steering wheel audio switch. NO: Check the TCM and Instrument Cluster for related DTCs. Check the steering wheel speed and audio control switch circuits. Refer to «Speed Control»(ref-312569-S01624038322009041400000) and «Audio System»(ref-312596-S08004659692009041400000) article. Refer to the appropriate system wiring diagrams article and test the LIN circuit between the steering wheel audio switch and the instrument cluster.

1. Remove the rear seat armrest. Refer to «Rear Seat Armrest»(ref-312549-S32221670662009041400000) article.
2. Remove the floor console veneer trim panel. Refer to «Floor Console Finish Panel»(ref-312550-S23819977062009041400000) article.
3. Remove the floor console rear panel. Carefully release the 2 clips.
4. Remove the floor console side panel trim. Remove the 2 Torx bolts. Carefully release 11 clips. Repeat the procedure and remove the opposite hand.
5. Carefully disconnect the selector cable ball joint. Apply gentle pressure.
6. Release the gear selector cable at the abutment. Loosen the 2 lock nuts.
7. Fully extend the inner cable while supporting the outer, then retract the inner cable one detent.
8. Using the transmission selector lever, position to the REVERSE detent.
9. Install the gear selector cable to the floor console abutment. Position and lightly tighten the adjusting nuts.
10. Connect the selector cable ball joint. Adjust the cable, until the ball joint socket aligns with the ball, on the transmission selector lever.
11. Check the operation of the transmission selector lever through the gate and detents. If the adjustment is correct, tighten the lock nuts to 20 Nm (14 lb.ft).
12. Install the floor console side panel trim. Carefully align and secure the clips. Tighten the Torx screws to 6 Nm (4 lb.ft). Install the opposite hand.
13. Install the floor console rear panel. Align the lugs and secure the clips.
14. Install the floor console veneer trim panel. Refer to «Floor Console Finish Panel»(ref-312550-S23819977062009041400000) article.
15. Install the rear seat armrest. Refer to «Rear Seat Armrest»(ref-312549-S32221670662009041400000) article.
