Peugeot 308: Check - recharge : Service battery tester "E-XTEQ"

ESSENTIAL : Observe the safety and cleanliness recommendations .

ESSENTIAL : All personnel carrying out work on a vehicle fitted with traction batteries must have received specific electric vehicle training and be authorised to work on these vehicles (observe the regulations in force in the respective country).

Only a battery tester can diagnose the general condition of the ancillaries battery, the tester diagnosing not only the state of charge of the ancillaries battery, but also its ability to be recharged.

The diagnostic tool permits :

• Measuring the voltage of the ancillaries battery (Ancillaries battery state of charge)
• Measuring the conductance of the ancillaries battery (Capacity of the ancillaries battery to drain and to recharge itself)

Measuring the voltage of the ancillaries battery with a simple voltmeter does not allow you to evaluate the ancillaries battery’s state of health, nor its real recharging ability.

CAUTION : Perform the operations to be carried out before disconnection or after reconnection of the ancillaries battery .

CAUTION : The periodic check is the responsibility of the owner of the "E-XTEQ" tester.

4.1. Checking the condition of the ancillaries battery

N.B. : No need to disconnect and remove the ancillaries battery.

CAUTION : If the measuring tool is configured incorrectly, this results in the ancillaries battery being misdiagnosed.

N.B. : (*) According to equipment.

When configuring the measuring tool, the measuring configuration must be specified :

• On the negative terminal of the ancillaries battery (*)
• On the remote negative terminal on the bodywork (*)
• On the remote negative terminal present on the negative electrical harness (*)
• On the earth point close to the ancillaries battery (*)

When the negative terminal is not accessible and the vehicle is not fitted with a remote negative terminal, use the earth point close to the ancillaries battery and configure the measuring tool in remote terminal mode.

CAUTION : If there is an auto-configuration number on the AS/RP label, use this number to configure the measuring device automatically (auto-configuration) and avoid diagnostic errors (Refer to the "Additional information" section).

N.B. : The auto-configuration number is an encoded sequence of the ancillaries battery type coding (BK-XXXXXX-X).

Check the condition of the ancillaries battery.

Refer to the method : Instructions for use - "E-XTEQ" battery tester.

N.B. : When the negative terminal is not accessible and the vehicle is not fitted with a remote negative terminal, use the earth point close to the ancillaries battery.

6. Definitions

6.1. Definition of the vehicle rest required before reading the voltage

A vehicle is considered to be at rest either if it has remained untouched (its engine not started, its lamps not switched on, the display "READY" not showing in the instrument panel, etc.) for at least one hour prior to the checking of the voltage, or if it has gone through the procedure for being placed at rest as described below.

CAUTION : If accessing the ancillaries battery necessitates leaving one of the doors open, manually close the catch of the lock of the door involved, to decoy the electrical system.

Procedure for placing the vehicle at rest :

• Switch on the headlamps for 2 minutes
• Switch off the headlamps
• Close the vehicle’s doors and do not carry out any action for 10 minutes
• Check the voltage before starting the engine
• If the catch of the lock of the door involved has been manually closed, return it to the open position

6.2. Definitions of the ancillaries battery voltage thresholds when at rest

Value of the voltage measured at rest	Action
Voltage greater than 12,6 V	None
Voltage between 12 V and 12,6 V	Recharge the ancillaries battery in accordance with the instructions given below
Voltage less than 12 V	Replace the ancillaries battery in accordance with the instructions given below

7. Recharging the ancillaries battery

7.1. Recommendations and instructions

CAUTION : Recharging the ancillaries battery on the vehicle using tooling that does not meet the specifications described below may cause the destruction of the ECUs on the vehicle.
