9. Identify hybrid vehicle auxiliary (12v) battery service, repair, and test procedures. P-3.

          In auto 170 we learned about the dangers of hybrid vehicles. Hybrid vehicles run extremely high voltages and currents so much so it could easily kill a person. So we learned just exactly the proper procedures to take when handling hybrid cars. Hybrid cars use orange cables to indicate the high voltage circuits and special care is to be used with them.

8. Identify electronic modules, security systems, radios, and other accessories that require reinitialization or code entry after reconnecting vehicle battery. P-1.

           In auto 170 we learned that disconnecting the battery can cause the clock or radio stations to be reset. Using service info on AllData to do the proper manufacture protocols to store the info. Some vehicles require a special tool to keep a voltage going to the radio clock and such. Newer systems allow info to be stored and set using a obd2 scan tool. 

7. Identify high-voltage circuits of electric or hybrid electric vehicle and related safety precautions. P-3.

          In auto 170 we learned about the dangers of hybrid vehicles. Hybrid vehicles run extremely high voltages and currents so much so it could easily kill a person. So we learned just exactly the proper procedures to take when handling hybrid cars. Hybrid cars use orange cables to indicate the high voltage circuits and special care is to be used with them.

6. Jump-start vehicle using jumper cables and a booster battery or an auxiliary power supply. P-1.

            Little known to most people jump starting someone's car can be very dangerous and in some cases can damage your own vehicle. Its important to know the proper way of connecting jumper cables. First connect the positive to the good battery, then the negative to the good battery. Next connect the other positive to the bad battery, then connect the other negative to a ground source at least 18 inches away from the battery. 

5. Perform slow/fast battery charge according to manufacturer’s recommendation.P-1.

            In auto 170 we set up battery chargers on the vehicles in the lab on a slow stable charge from manufacture specifications. When set on fast charge its very important to monitor the battery's temperature to avoid explosions or damage to the battery. Always connect the connectors before turning on the machine to avoid sparks and explosions.

4. Inspect and clean battery; fill battery cells; check battery cables, connectors, clamps, and hold-downs. P-1.

          Batteries over time will corrode at the terminals with calcium. To prevent this dielectric grease is put on the terminals to slow the corrosion. In some cases the corrosion will cause excess resistance or even produce an open in the system. A simple wire brush is the best to use for cleaning the battery posts. Another way to clean them is to poor coke on the terminals to remove corrosion.

3. Maintain or restore electronic memory functions. P-1.

           In auto 170 we learned that disconnecting the battery can cause the clock or radio stations to be reset. Using service info on AllData to do the proper manufacture protocols to store the info. Some vehicles require a special tool to keep a voltage going to the radio clock and such.
