The judgment method of a charge end

When the specific gravity of the battery electrolyte is 
constantly within 1.250 

− 1.290 for a continuous 

period of one hour or more.

BATTERY TEST

M1541001200755

TEST STEPS

STEP 1. Battery no-load voltage check
(1) Illuminate the headlamp for 15 seconds.
(2) Turn off the headlamp and then leave it for about 

2 minutes to stabilise the battery voltage.

(3) Remove the battery cable.
(4) Measure the battery no-load voltage.

OK: 12.4 V or more (Specific gravity 
1.240)

Q: Does the measured voltage correspond with this 

range?
YES : 

Go to Step 3.

NO : 

Go to Step 2.

STEP 2. Battery charging

Q: Does the battery recharge?

YES : 

Recharge the battery at 5A 

(constant-current charging) and then go to 
Step 1 (Refer to Table 1).

NO : 

Go to Step 3.

STEP 3. Load test check
(1) Connect the battery tester to battery.
(2) Feed a load current through the battery (Refer to 

Table 1).

(3) Measure the battery voltage after 15 seconds and 

then eliminate a load current.

(4) Compare the measured voltage to the specified 

lowest voltage (Refer to Table 2).

Q: Is the measured voltage higher than the lowest 

voltage?  
YES : 

The battery is normal.

NO : 

Replace the battery.

ENCRYPTED CODE REGISTRATION CRITERIA TABLE

M1543026000260

The ignition key contains a transponder (small trans-
mitter), which retains an unique encrypted code. 
Under any of the conditions below, the encrypted 
code must be registered in the immobiliser-ECU 
again. The immobiliser-ECU can retain maximum 
eight different encrypted codes. This means that 
maximum eight ignition keys can be registered.
