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 Battery Power Supply to the vehicle battery.

3. Connect the Symptom Driven Diagnostics (SDD) system to the vehicle and begin a new 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 Central Junction Box (CJB) have correct power and ground connections?
Record readings 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 (< 1 Ohm)
• Range Rover Evoque only: Connector C1BP02D: 16, 20, 21, 22 (12V)
• Range Rover Evoque only: Connector C1BP02F: pin numbers 05, 25 (< 1 Ohm)
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: The Central Junction Box (CJB) may also be referred to as the Body Control Module
(BCM).

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) (see TOPIx Workshop Manual, Section 418-00).

11.
CAUTION: If the SDD 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'.
