REPAIR PROCEDURE:

NOTE: All vehicle keys must be present before continuing with this Repair Procedure.

1. Check that the battery is correctly charged (see battery care manual), has good connections to the vehicle,
and that the transit relay has been removed.

2.

CAUTION: SDD must be loaded with DVD131.09 v.120 later.
Connect the Jaguar Land Rover-approved Midtronics Vehicle Power Supply to the vehicle battery.

3. Connect the Integrated Diagnostic 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, choose 'Diagnosis'.
6. Select the 'Selected Symptoms' tab, and then select one of the following:
Body > Security and locking > Handles locks and latches or
Powertrain > Engine system > Starting system > Will not start > Will not crank

7. Identify fault codes related to the starting system and diagnose as required.
8. Does the CJB have correct power and ground connections?

Record voltages at:

• LR4, Range Rover Sport, Range Rover only: Connector C0583: pin numbers 16, 20, 21, 22 (12V)
• LR4, Range Rover Sport, Range Rover only: Connector C0585: pin numbers 05, 25 (0V)
• Range Rover Evoque only: Connector C1BP02D: 16, 20, 21, 22 (12V)
• Range Rover Evoque only: Connector C1BP02F: pin numbers 05, 25 (0V)
If any of the readings are incorrect, investigate and rectify if necessary before proceeding to step 9.

9. Check the operation of the hazard lamps:
If the hazard lamps do not operate outside the vehicle, continue to step 10.
If the hazard lamps do operate outside the vehicle, do NOT continue; further diagnosis will be required to

identify the failure mode.

10.
NOTE: Prior to performing the following instructions, ensure a new Central Junction Box for
the vehicle (CJB) is available if necessary.

NOTE: All vehicle keys must be present before continuing.
Replace the Central Junction Box (CJB) (TOPIx Workshop Manual section 418-00).

11.
CAUTION: If the IDS and battery power supply have been removed, the previous SDD session
must be resumed; do not start a new SDD session.
From the Session Type selection screen, choose 'Diagnosis'.
12. Select the 'Selected Symptoms' tab, and then select one of the following:
Body > Security and locking > Handles locks and latches or
Powertrain > Engine system > Starting system > Will not start > Will not crank

13. Select the ‘Recommendations’ tab.
14. Read one of the SSMs listed to expose the ‘Extras’ tab.

15.
NOTE: NOTE: When asked if a new CJB has been installed, select the 'X' and then continue
with the SDD procedure. SDD will now attempt to communicate with the new CJB to extract data.
This is an expected result.
Select ‘Run’ to perform the 'Configure new modules - Body control module' application.

16.
NOTE: During the routine, the CJB will have several applications performed: immobilization
routine to enable security; software download to load the latest level of software; CCF download to
store the vehicle's data to the new module; key programming routine; key validation routine; fault
code clear. Ensure all of the above applications complete successfully. If at any time a failure is
encountered, you will be required to start the process over in entirety from step 15.
Continue with the SDD routine by following all on-screen prompts, including performing the software
download. Do not skip the software download routine.
17. Select the Recommendations tab.
18. Select ‘Run’ to perform the ‘Body System – Variable assist power steering curves’ application.
19. Follow all on screen prompts to complete this task.
