Initial Installation - RHD

WARNING: This page is about a different car, the 2025 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.
    NOTE: Before starting the installation procedure, check that the control module is compatible with the vehicle model on which it will be installed.
    Carefully follow the instructions on positioning and securing the control module described in this procedure. Failure to respect indications may lead to incorrect system operation.
  2. Make a note or take a photo of the data on the label (1) at the rear of the module. This data are necessary for the test procedure at the end of the installation.

  6. Remove the glove compartment. Refer to GLOVE BOX, INSTRUMENT PANEL, REMOVAL AND INSTALLATION .
  7. Remove the passenger cowl trim. Refer to PANEL, COWL TRIM, REMOVAL AND INSTALLATION .
  8. Release the lower B pillar trim and move it aside without removing it completely. Refer to PANEL, B-PILLAR TRIM, LOWER, REMOVAL AND INSTALLATION .
  9. Clean the contact surface (1) where the T-box module will be fixed using isopropyl alcohol, heptane or an equivalent degreaser.

  15. If there are previously removed wires connected to the ground stud, be careful to insert the earth wire of the T-box harness so that it is offset correctly (1) by at least 45° with respect to the previous ones. Do NOT  stack the ring terminals (2).

  16. Staring at the center of the kick plate, gather the branch of the module wiring that comes from the module and the ground stud terminal. Open the vehicle wiring clip, pass the cable, close the wiring clip and use a cable tie to consolidate them (1). Do NOT  allow the wires to stay unsecured (2).

  17. Disconnect electrical connector C3 (1) from the Body Control Module (BCM) and remove the inner connection covering block.

  18. Locate pin (1) (+ 50) (red/green cable cross-section 2.5 mm) on the connector. Cut and move aside the sheathing of the vehicle wiring.
    NOTE: Be sure on the next step to interrupt the cable at a distance of 150-200 mm from the connector to be able to completely cover the work performed with new tape.
    NOTE: Take great care not to get the cables to be joined dirty as this will adversely affect the continuity of the electrical conduction. While heating the thermal shrinking tubs, as a result of the high temperatures reached, the drier and the heat shield must not, under any circumstances, come into contact with cladding parts or other components.
    NOTE: The air heater (drier) used in this procedure is commercially available.
    NOTE: Recommend applying insulating tape on the two wires separately and then joining the wires to the vehicle wiring and applying more tape to make it more compact.

  19. Use an air heater (2a) with heat shield (2b) to heat the thermal shrinking tubes (2c) until the ring of solder melts; then wait for it to cool.
    NOTE: Apply insulating tape to the two wires individually and then combine the wires with the main wiring and tape again to create a more compact bundle.
  20. Remove fuse F36 (1) from the BCM and fit it in the twin fuse holder of the module wiring.
    NOTE: Fuse F36 is the third from the top right (blue) in the right-hand row in the Body Computer.

  22. Remove fuse F51 from the Body computer and install it in the twin fuse holder.
    NOTE: Fuse F51 (red) is the fourth from the bottom in the left-hand row in the Body Computer.
  23. Install the twin fuse holder in the position previously occupied by fuse F51.
  24. Disconnect the electrical connector C6 (1) from the BCM and remove the inner connection covering.
    NOTE: When done, restore the connector wiring with a new tie.

  26. Locate pins 57 CAN-L (1) and 58 CAN-H (1).
  27. Using signal taps (2) (cross-section area 0.35 mm), connect the two wires CAN-L (white) and CAN-H (blue) to the corresponding loose wires in the module harness.

    When done, restore the connector wiring with a new tie.

  28. Connect the door opening signal wire (green) of the new T-box harness to the pin 11 position (2) and replace the internal connection cover block of the BCM electrical connector F.
    NOTE: Tape should be applied to the bundle of cables to increase its compactness.

  31. Install the B-Pillar panel. Refer to PANEL, B-PILLAR TRIM, LOWER, REMOVAL AND INSTALLATION .
  32. Install the passenger cowl trim. Refer to PANEL, COWL TRIM, REMOVAL AND INSTALLATION .
  33. Install the glove compartment. Refer to GLOVE BOX, INSTRUMENT PANEL, REMOVAL AND INSTALLATION .
    NOTE: Using the scan tool, select the "Connected Services " tab, select "Mopar Connect" and choose "Test-Operation check" option. Start a new test and complete steps 2 and 3 of the "Test App" manual (which can be downloaded from the Help section).
  34. Connect the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector.
    NOTE: Complete the test procedure to check that the installation is operating correctly (to resume a previously suspended procedure, see step 9 of the "Test App" manual).
