CONNECTOR 

The connector pin shape determines whether the connector is 
male or female. 
The connector housing configuration does not determine 
whether a connector is male or female. 
 

 

 
 

The symbol illustrated in the figure is used as connector in the 
circuit this section. 
 

 

 

 

RTW78ASH003101 

 
 

Connector is identified with a number. 
 

 

 

 

RTW78ASH003201 

 
 

The applicable terminal number is shown for each connector. 
 

 

 
 

Connector terminal numbers are clearly shown. 
Male side connector terminal numbers are in sequence from 
upper right to lower left. 
Female side connector terminal numbers are in sequence from 
upper left to lower right. 
NOTE: 
For those connectors on which specific terminal numbers 
on symbols are shown, the terminal numbers or symbols 
are used in the circuit diagram, irrespective of the above 
rule.

 for corrosion. 

2.  Check the battery cables 

2

 for looseness. 

3.  Check the battery case 

3

 for cracks and other damage. 

4. Check the battery electrolyte level.

Jump Starting the Engine with a Booster Battery

The following description assumes that you are using a booster 
battery mounted on a second vehicle. 
The listed steps (with some minor modifications) are also 
applicable if you are using a naked booster battery or special 
battery charging equipment.

Caution: 
Never push or tow the vehicle in an attempt to start it. 
Extensive damage to the emission system and other 
vehicle parts will result. 
(Only catalytic converter vehicle) 
Treat both the discharged battery and the booster battery 
with great care when using jumper cables. 
Carefully follow the procedure outlined below. 
Always be aware of the dangers of sparking. 
Failure to follow the following procedure can result in: 
a.  Serious personal injury, specially to your eyes. 

b. Extensive property damage from a battery explosion,

battery acid discharge, or electrical file. 

c. Extensive damage to the electronic components of

both vehicles. 

Do not use a 24 volt booster battery. 
Serious damage to the vehicle's electrical system and 
electronic components will result. 
 

Jump Starting Procedure 

1.  Set the parking brake on both vehicles. 

2. If one or both vehicles is equipped with a manual

transmission, place the gear shift in the "NEUTRAL"

position. 

3.  Turn off the ignition on both vehicles. 

4.  Turn off all vehicle lights and accessories. 

5  Be sure that the two vehicles are not touching. 

 

Attach the end of one jumper cable to the booster battery

positive terminal. 

6  Attach the other end of the same cable to the discharged

battery positive terminal. 

7.  Once again, check that the booster battery has a 12 volt

rating. 

8.  Attach one end of the remaining booster cable to the

booster battery negative terminal. 

9.  Attach the other end of the booster cable to a solid ground

(such as the air conditioner compressor mounting bracket 

or the alternator mounting bracket) in the engine room of

the vehicle with the discharged battery. 

10.Be sure that the ground connection is at least 500 mm (20

in) from the discharged battery.

Caution: 
Do not attach the booster cable to the discharged battery 
negative terminal. 
 
11. Start the engine of the vehicle with the booster battery. 

 

Check that all unnecessary electrical accessories are off. 

12. Start the engine of the vehicle with the discharged battery. 

13. Remove the jumper cables in the reverse order to which

they were attached. 

Caution: 
Be absolutely sure to remove the negative jumper cable 
from the vehicle with the discharged battery first.
