• NOTE:
1. The total current drain will be higher if certain approved accessories are fitted (for example: tracker, trailer module,
etc.)
2. Applies to vehicles without Tire Pressure Monitoring System (TPMS). Vehicle shut-down period with TPMS is
approximately 15 minutes.

Diagnosis and Testing
Principles of Operation
For a detailed description of the charging system, refer to the relevant Description and Operation section in the workshop
manual. REFER to:
Battery Care (414-00, Description and Operation),
Battery and Cables (414-01, Description and Operation),
Generator - ID4 2.4L Diesel (414-02, Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does
not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor
vehicle.
1. Verify the customer concern.
1.
2. Visually inspect for obvious signs of mechanical or electrical damage.
2.
• NOTE: Check the vehicle battery condition and state of charge before condemning any of the charging system
components. For additional information, refer to the battery care manual.
For a complete list of all diagnostic trouble codes that could be logged on this vehicle, please refer to section 100-00.
REFER to: (100-00)
Diagnostic Trouble Code (DTC) Index - DTC: Engine Control Module (PCM) (Description and Operation),

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, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index
• NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior
to the installation of a new module/component.
• NOTE: Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the
scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra
information read by the manufacturer-approved diagnostic system).
• NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three
decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the
DMM leads into account.
• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
• NOTE: If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may
be the cause. Always check for loose connections and corroded terminals.

Test Procedure
PINPOINT TEST A : BOSCH NON-BMS GENERATOR DIAGNOSTIC FLOW CHART
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
A1: MIDTRONICS BATTERY TEST
• NOTE: The battery must be fully charged and any battery defects rectified before continuing with generator diagnosis
• NOTE: The voltmeter must display readings to three decimal places (i.e. 0.001V)
• NOTE: Ignition on is position 2 on a keyed ignition system
• NOTE: Ignition on is two short presses of the start button (power mode 6) with keyless ignition system
Using a Midtronics hand held tester or the Midtronics GR-1 diagnostic charger, carry out the
"Midtronics battery test" as detailed in the battery care manual.
REFER to: Battery Care (414-00, Description and Operation).
Record battery diagnostic result on the provided form
Does the battery pass the "Midtronics battery test"?
Yes
GO to B1
.
No
Rectify any battery defects before continuing with generator diagnosis GO to Pinpoint Test

TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
B1: GENERATOR OUTPUT
• NOTE: Freelander 2 = The heated rear screen is timed to operate for 12 minutes
• NOTE: Defender = The heated rear screen is timed to operate for 8 minutes
Connect a voltmeter to the vehicle battery
Switch ignition state to on (engine off)
Turn off all electrical loads e.g. (blower, radio, interior lights etc.)
Start the engine, switch on the heated rear screen
Ensure the heated rear screen is on (see note above) and that the air conditioning system is off.
Wait 90 seconds
Record the battery voltage (V1) shown on the multimeter
Does battery voltage (V1) = 14.8 volts or greater at idle?
Yes
Install a new generator. Refer to the warranty policy and procedures manual, or determine if any
prior approval programme is in operation, prior to the installation of a new module/component
No
GO to B2
.
B2: BATTERY VOLTAGE AT IDLE
Using battery voltage reading (V1)
Does battery voltage (V1) = 13 volts or greater at idle (But less than 14.8 volts)?
Yes
GO to B3
.
No
GO to Pinpoint Test
C.
B3: BATTERY WARNING LAMP
The battery voltage is (V1) = 13 volts or greater at idle (but less than 14.8 volts)
