Battery Inspection and Maintenance During PDS
Introduction

A battery in a stored vehicle is subject to conditions that can reduce its performance and service
life. These conditions include storage period, temperature, parasitic drain, and battery load.
Because of these factors, battery inspection and maintenance are required in order to ensure
proper operation and optimal battery life.
Refer to the table below for a definition of terms used in this bulletin.

DEFINITION

Conventional Vehicle

CV

A vehicle with only a gasoline engine for propulsion

Electrified Vehicle

EV

A vehicle that utilizes a hybrid, plug-in hybrid, or battery
electric system for propulsion

Hybrid Electric Vehicle

HEV

A vehicle with both a gasoline engine and a HV Battery

Plug-in Hybrid Electric Vehicle

PHEV

Battery Electric Vehicle

BEV

A vehicle with only a HV Battery that can be
charged externally

State of Charge

Standard 12V battery used to power electrical systems
separate from high voltage components

High Voltage

HV

HV Battery used to power the electrified vehicle

A vehicle with both a gasoline engine and a HV Battery that
can be charged externally

Electrified vehicles are equipped with two types of batteries, a HV battery and a 12V battery.
Conventional vehicles are equipped with only a 12V battery.
As a matter of policy, Lexus does not provide battery warranty coverage for discharged and/or
failed batteries due to lack of maintenance. It is the dealer’s responsibility to maintain the specified
SOC of the vehicle’s battery while in stock and ensure proper SOC at delivery.
To reduce customer service concerns due to an undercharged battery, ALL dealers should test
the 12V battery and recharge, if necessary, no more than 48 hours before delivery to
the customer.
CAUTION
Refer to the precautions listed in the DSS-5000 Instruction Manual and DCA-8000 Instruction
Manual located at TIS – Diagnostics – Tools & Equipment – Battery Diagnostics.

Battery Inspection and Maintenance During PDS
Battery Inspection Procedure

Test the 12V battery using the DSS-5000 Battery Diagnostic Tool’s PDI mode or the DCA-8000
Battery Diagnostic Tool’s PDS/PDI mode. ALWAYS perform the battery test directly on the battery
terminals, avoid testing the 12V battery using alternate charging posts or grounds.
NOTE
 ALL vehicles MUST be inspected and charged no more than 48 hours BEFORE delivery to
the customer.
 Ensure ALL doors stay closed and lights remain OFF during battery testing and charging.
 For details on how to use the battery diagnostic station, refer to the DSS-5000 Instruction Manual
and DCA-8000 Instruction Manual located at TIS – Diagnostics – Tools & Equipment –
Battery Diagnostics.

NOTICE
In vehicles equipped with both a 12V battery and a hybrid battery, the DSS-5000 and
DCA-8000 Battery Diagnostic Tool is ONLY to be used on the 12V battery.

Battery Inspection Results

The PDS/PDI mode was developed to confirm the battery's State of Charge (SOC) to ensure
the proper operation and optimal battery life. The DSS-5000 will check the battery's SOC and
recommend charging when necessary. The DCA-8000 will check the battery's SOC and
automatically charge the battery. Once the PDS/PDI mode completes, proceed with one of the
procedures below according to the battery condition results.
DSS-5000 Results

1.
2.

“PDI Complete” – Return the battery to service.
“PDI Incomplete” – Fully charge the battery using the DCA-8000 in PDS/PDI mode.

3.

“PDI Fail” – detected a battery concern, test the battery using the DCA-8000 in
Advanced Battery Test mode.

DCA-8000 Results

1.

“PDS/PDI Complete” – Return the battery to service.

2.

If the PDS/PDI mode detects a battery concern, test the battery using the DCA-8000 in
Advanced Battery Test mode.

Battery Inspection and Maintenance During PDS
Battery Replacement Procedure

If a vehicle battery needs to be replaced for a
warrantable condition, complete a Warranty
Battery Label and affix it to the failed battery for
proper warranty parts and claim processing.
Include the Vehicle Identification Number
(VIN) and warranty code on the Warranty
Battery Label.

Figure 1.

Periodic Battery Maintenance

In addition to this pre-delivery battery test, periodic battery maintenance is still required for stored
vehicles. If your dealership is in an area subject to extreme temperatures (hot or cold), periodic
maintenance may need to be performed more frequently.
If the vehicle is stored for over 30 days, be sure to follow Long-Term Vehicle Storage Guidelines.
To reduce parasitic battery drain on vehicles that are placed in storage for one week or more, the
negative (–) battery cable should ALWAYS be disconnected to reduce battery discharge.
When the negative (–) battery cable is reconnected, check and reset electrical components, such
as the clock, radio, etc., and re-initialize ALL applicable systems/functions.
Refer to the appropriate model and year Repair Manual for torque specifications:
Repair Manual – General – Maintenance – Battery – Installation.

Battery Inspection and Maintenance During PDS
Maintenance for HV Battery during PDS (HEV and PHEV models)

The SOC of the HV battery may have gradually decreased during the time the vehicle was being
transported to your dealership. To prevent the HV battery from deteriorating, perform the following
maintenance service at the time of PDS.
Charging the HV battery

1. Park the vehicle in open air or connect the
exhaust extraction hose to the exhaust pipe.

Figure 2

2. Apply the parking brake.
3. With the brake pedal depressed, select the
power switch to the “START” mode, and
check that the “READY” light in the
combination meter illuminates when the
hybrid system starts (the “READY” light
is ON).
4. Turn OFF ALL lights and accessories.
5. Check that the shift lever is in the
“P” position.
6. Keep the “READY” light ON and charge the
HV battery for 30 minutes.
NOTE
 If the amount of charging energy is small, the display may NOT indicate the energy flow.
 Ensure there is a sufficient amount of fuel in the vehicle to run for at least 30 minutes.
HINT
The HV battery can also be charged by driving the vehicle for 30 minutes.

Maintenance for HV Battery during PDS (BEV models)

BEV models store electricity received via an external power source in the HV battery. The SOC of
the HV battery may have gradually decreased during the time the vehicle was being transported
to your dealership reducing vehicle range. To prevent the HV battery from fully discharging,
perform the following procedure at the time of PDS to maintain the charge level of the HV battery.

1. If the warning light is displayed ON within the combination meter, charge the HV battery via the
AC charging method.

2. After charging has been completed, verify the HV battery warning light is OFF before storing
the vehicle long-term. If the HV battery warning light is still ON after charging, repeat the
charging process.
NOTE
 Model-specific information for charging the HV battery, charging equipment, and charging method
can be referenced from the vehicle’s owner’s manual. Avoid using the DC charger for supplementary
charging during PDS.
 For additional vehicle care points, reference the model specific PDS bulletin and PDS check sheet.
 Refer to Long Term Storage Guidelines when the vehicle is to be stored for more than 30 days at the
dealership.
