Pinpoint Test A: Battery Health Checks
- A1: RECORD BATTERY VOLTAGE AND ATTEMPT ENGINE START
- If the vehicle has been recovered to the retailer, then, using a Digital Multi Meter (DMM), record the battery open circuit voltage and make a note of the voltage
- Attempt to start the engine
Does the engine start unaided?
Yes: GO to PINPOINT TEST B .
No: Complete the RECOVERY CHARGING process using a manufacturer approved battery charger. If either a Midtronics GRX-3080 or GR8-1180 Diagnostic Battery Charger is available, then follow the Recovery Charging procedures as described elsewhere in this service information REFER to:
BATTERY DIAGNOSTICS - 12 VOLT MIDTRONICS GRX-3080 JLR DIAGNOSTIC BATTERY CHARGER (Diagnosis and Testing),
BATTERY DIAGNOSTICS - 12 VOLT MIDTRONICS GR8-1180 JLR DIAGNOSTIC BATTERY CHARGER (Diagnosis and Testing).
If no suitable tools (ie: with access to Recovery Charging procedures) are available, then charge the battery for 1 hour. When charging/recovery charging has been completed, then GO to A2.
- A2: BATTERY TESTING
- To confirm the state of battery health, refer to the appropriate Midtronics Battery Diagnostics/Battery Charger procedures and follow the on-screen instructions REFER to:
BATTERY DIAGNOSTICS - 12 VOLT MIDTRONICS EXP-1080 JLR HAND-HELD BATTERY DIAGNOSTIC TOOL (Diagnosis and Testing),
BATTERY DIAGNOSTICS - 12 VOLT MIDTRONICS GRX-3080 JLR DIAGNOSTIC BATTERY CHARGER (Diagnosis and Testing),
BATTERY DIAGNOSTICS - 12 VOLT MIDTRONICS GR8-1180 JLR DIAGNOSTIC BATTERY CHARGER (Diagnosis and Testing).
After completion of the battery testing procedures as above, do the results indicate "Good Battery"?
Yes: GO to PINPOINT TEST B .
No: If using the Midtronics EXP-1080 JLR Hand-Held Battery Diagnostic Equipment, the process flow may result in a "REPLACE BATTERY" decision. In this case, with reference to the relevant service information, replace the battery taking care to complete the battery replacement process in order to appropriately clear/reset the BMS , then GO to PINPOINT TEST B .
