CONDITION SUMMARY:
Situation:
The Transmission Control Switch (TCS) may fail to rise, fail to rotate out of Park (P), and/or fail to rotate between gears. This bulletin is to aid in diagnosing of Diagnostic Trouble Codes (DTC) for the Transmission Control Switch (TCS) module.
NOTE:
The Transmission Control Switch (TCS) may also be referred to as:
^ Electronic Transmission Switch (ETS)
^ Gear Selector Module (GSM)
^ JaguarDrive Selector
^ Transmission Range Selector (TRS)
^ Transmission Rotary Switch (TRS)
^ Transmission Shift Module (TSM)
NOTE:
Use the table below to assist with the diagnosing of the various Diagnostic Trouble Codes (DTC).
NOTE:
Repairs to be carried Out as a separate claim.
Cause: These may be caused by various issues which make the TCS fail to operate.
Action: In the event of a customer concern of the above, refer to the Diagnostic Procedure outlined below.
PARTS:
No Parts Required
TOOLS:
IDS with latest IDS-DVD and Calibration File
Jaguar Land Rover-approved Midtronics Vehicle Power Supply
WARRANTY:
DIAGNOSTIC PROCEDURE:
Use the Diagnostic Trouble Codes (DTC) table below for the Transmission Control Switch (TCS) module fault diagnosis.
The above DTCs may be generated by Brake Pedal pressure or Brake Pedal Switch DTCs. Follow the Diagnostic Procedure below for Brake Pedal Switch/Brake Pedal Pressure Diagnostics.
1. CAUTION:
Ensure all ignition 'ON' / ignition 'OFF' requests are carried out; failure to perform these steps may cause damage to control modules in the vehicle.
CAUTION:
A Jaguar Land Rover-approved Midtronics Vehicle Power Supply must be connected to the vehicle battery during IDS/SDD diagnosis / module programming.
Connect a Jaguar Land Rover-approved power supply to the vehicle.
2. Turn the ignition 'ON' (engine not running).
3. Connect the Integrated Diagnostics System (IDS) to the vehicle and begin a new Symptom Driven Diagnostics (SDD) session.
4. Follow the on-screen prompts, allowing SDD to read the VIN and identify the vehicle.
5. From the Session Type selection screen, select 'Measurement Applications'.
6. Select the 'Recommendations' tab.
7. From the Recommendations tab run 'Complete data logger'.
8. Select / expand the '206-00 Brake system' tab.
9. Select 'Brake fluid hydraulic pressure' and click on the icon (1) shown.
10. Expand Engine system.
. Select 'Engine input/output parameter - Brake switch 2' then click on the icon shown (2).
11. Select 'Engine input/output parameter - Brake switch' (1) then click on the icon shown (2).
12. Click on the icon shown.
13. Click on the icon shown.
14. Press the brake pedal.
^ The first graph to change must be the brake light switch (confirm by asking someone to watch brake lights come on). The brake pressure applied, shown in the top bar chart, should be between 1 and 7 BAR.
15. The next graph to change should be the cruise cancel switch.
. The brake pressure applied, shown in the top bar chart, should be between 4.5 and 14 BAR.
16. Last graph to move should be brake pressure.
^ This reading will vary depending on whether the engine is running and foot pressure applied.
17. Switch the data logger off before disconnecting the SDD from the vehicle.
^ If the results show that the brake pedal switch is working as expected do not replace the switch. It will be necessary to investigate the cause of the issue. Contact the Technical HelpLine for additional support if necessary.
^ If the results show that the brake switch is not working correctly, remove the brake pedal switch and refit.
^ Run the above tests again.
^ If the results still show the brake switch is not working correctly the switch should be replaced.
18. Exit the current session.
19. Disconnect the IDS and the battery conditioner/power supply from the vehicle.
