On-Vehicle Inspection [09/2013 - ]
WARNING: This page is about a different car, the 2014 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK AUXILIARY BATTERY
- Check that the auxiliary battery cables are connected to the correct terminals.
HINT:
If they are not, connect them properly.
- Check the auxiliary battery for damage and deformation. If severe damage, deformation or leakage is found, replace the auxiliary battery.
- Check that the auxiliary battery cables are connected to the correct terminals.
- CHECK AUXILIARY BATTERY VOLTAGE
- Turn the power switch off and turn on the high beam headlights for 30 seconds. This will remove the surface charge from the auxiliary battery.
- Measure the auxiliary battery voltage according to the value(s) in the table below.
Result
Tester Connection Condition Specified Condition Result Positive (+) terminal - Negative (-) terminal 20°C (68°F), Power switch off 12.5 V or higher Auxiliary battery is OK 11.0 to 12.5 V Recharge auxiliary battery Below 11.0 V Replace auxiliary battery
- RECHARGE AUXILIARY BATTERY
- Recharge the auxiliary battery.
HINT:
- Recharge the auxiliary battery according to the charger's instructions.
- Apply the appropriate charging current according to the type of auxiliary battery as shown in the table below.
Auxiliary Battery Type Charging Current 55D23L 4 to 5 A - Turn the power switch off and turn on the high beam headlights for 30 seconds. This will remove the surface charge from the auxiliary battery.
- Measure the auxiliary battery voltage according to the value(s) in the table below.
Result
Tester Connection Condition Specified Condition Result Positive (+) terminal - Negative (-) terminal 20°C (68°F), Power switch off 12.5 V or higher Auxiliary battery is OK 11.0 to 12.5 V Recharge auxiliary battery Below 11.0 V Replace auxiliary battery
- Recharge the auxiliary battery.
- CHECK AUXILIARY BATTERY TERMINAL, FUSIBLE LINK AND FUSE
- Check that the auxiliary battery terminals are not loose or corroded.
HINT:
If the terminals are corroded, clean them.
- Measure the resistance of each fusible link and fuse for the auxiliary battery charging system.
Standard resistance
Below 1 Ω
HINT:
If any of the results is not as specified, replace the fusible link or fuse as necessary.
- Check that the auxiliary battery terminals are not loose or corroded.
- CHECK DC/DC CONVERTER FUNCTION
- Connect an AC/DC 400 A probe to the positive auxiliary battery cable.TEXT IN ILLUSTRATION
*a Probe Direction *b Current Flowing into Auxiliary Battery - Turn the power switch on (READY) and leave the vehicle as it is until the electric current flowing into the auxiliary battery becomes 10 A or less.
- Set the headlight position switch and blower motor switch to the HI position, and then turn the rear window defogger on.
- Measure the current and voltage according to the value(s) in the table below.
