STOP AND START SYSTEM DATA LIST / ACTIVE TEST
DATA LIST
Tip:Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
Note:In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
Warm up the engine.
Turn the ignition switch off.
Connect the GTS to the DLC3.
Start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Stop and Start / Data List.
According to the display on the GTS, read the Data List.
ACTIVE TEST
Tip:Using the GTS to perform Active Tests allows relays, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
Connect the GTS to the DLC3.
Start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Stop and Start / Active Test.
Perform the Active Test by referring to the table below.

*1: w/o Entry and Start System
*2: w/ Entry and Start System
*3: Regarding Battery Integrated Current
In the stop and start system, the engine stop and start ECU switches the system control mode (stop and start control permitted/prohibited) based on the battery condition (charge/discharge condition) to protect the battery and to ensure stable engine restarting performance.
The battery charge-discharge condition is determined from the integrated current value calculated from the battery current sensor (generator control ECU assembly) signal. The integrated current value is obtained by multiplying the current (Ampere) detected from the battery current sensor (generator control ECU assembly) by the time (seconds), and it is expressed in a unit A-sec.
Example: Integrated current of -3110 A-sec corresponds to a load where current of 10 A flows out from the battery for 311 seconds.
Using the Data List function of the GTS, the integrated current value can be read by checking the Data List item "Integrated Current". The item "Battery Integrated Current" shows the permission status of stop and start control (ON or OFF) and is judged from the "Integrated Current" value.
Negative integrated current represents battery discharge, and positive represents battery charge. In other words, the "Integrated Current" value of the Data List item will decrease from the present value when the battery is discharged, and the value will increase when the battery is charged.
The engine stop and start ECU determines the amount of power available based on the integrated current value, and it prohibits stop and start control if the value is below the threshold, because the battery might not be able to start the engine. The threshold varies according to the battery temperature.
Furthermore, the integrated current value is recorded inside the engine stop and start ECU memory even if the ignition switch is off, and when the ignition switch is next turned to ON, the value is calculated from the value recorded when the ignition switch was turned off.
Integrated Current Condition 1 (for 1AD-FTV):
The battery charge is sufficient and the battery temperature is -1°C (30.2°F) or higher and below 70°C (158°F):
Stop and Start System Operation (for Condition 1)
Phase A:
When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.
Phase B:
After the engine is started using the ignition switch, stop and start control is prohibited until the integrated current reaches 0 A-sec once. (The battery is being charged during this phase.)
Phase C:
Stop and start control is permitted until the integrated current value decreases to -6451 A-sec.
Phase D:
After the integrated current value decreases below -6451 A-sec, stop and start control is prohibited until the value increases to -5299 A-sec or higher again. (The battery is being charged during this phase.)
Phase E:
Stop and start control is permitted. After this, system control is permitted until the integrated current value decreases below-6451 A-sec.
Integrated Current Condition 1 (for 1ND-TV, 1NR-FE):
The battery charge is sufficient and the battery temperature is -1°C (30.2°F) or higher and below 70°C (158°F):
Stop and Start System Operation (for Condition 1)
Phase A:
When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.
Phase B:
After the engine is started using the ignition switch, stop and start control is prohibited until the integrated current reaches 0 A-sec once. (The battery is being charged during this phase.)
Phase C:
Stop and start control is permitted until the integrated current value decreases to -4838 A-sec.
Phase D:
After the integrated current value decreases below -4838 A-sec, stop and start control is prohibited until the value increases to -3974 A-sec or higher again. (The battery is being charged during this phase.)
Phase E:
Stop and start control is permitted. After this, system control is permitted until the integrated current value decreases below-4838 A-sec.
Integrated Current Condition 2 (for 1AD-FTV):
The battery charge is insufficient or the battery temperature is below -1°C (30.2°F) or 70°C (158°F) or higher:
Stop and Start System Operation (for Condition 2)
Phase A:
When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.
Phase B:
After the engine is started using the ignition switch, stop and start control is prohibited until the integrated current reaches 0 A-sec once. (The battery is being charged during this phase.)
Phase C:
Stop and start control is permitted until the integrated current value decreases to -1152 A-sec.
Phase D:
After the integrated current value decreases below -1152 A-sec, stop and start control is prohibited until the value increase to 0 A-sec or higher again. (The battery is being charged during this phase.)
Phase E:
Stop and start control is permitted.
Integrated Current Condition 2 (for 1ND-TV, 1NR-FE):
The battery charge is insufficient or the battery temperature is below -1°C (30.2°F) or 70°C (158°F) or higher:
Stop and Start System Operation (for Condition 2)
Phase A:
When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.
Phase B:
After the engine is started using the ignition switch, stop and start control is prohibited until the integrated current reaches 0 A-sec once. (The battery is being charged during this phase.)
Phase C:
Stop and start control is permitted until the integrated current value decreases to -864 A-sec.
Phase D:
After the integrated current value decreases below -864 A-sec, stop and start control is prohibited until the value increase to 0 A-sec or higher again. (The battery is being charged during this phase.)
Phase E:
Stop and start control is permitted.
The low battery temperature condition is detected when the battery temperature is less than 10°C (50°F). When the battery temperature becomes 11°C (51.8°F) or higher, the low battery temperature condition is cleared.
Performance (internal resistance) of lead-acid batteries used in typical vehicles changes according to the battery temperature. The internal resistance of the battery tends to be higher when the battery temperature is low. Thus, the stop and start system switches the threshold for determining the power charge according to the battery temperature when performing stop and start control.
If the battery is deteriorated, the internal resistance has also increased and the stop and start rate becomes lower. (The total of idling time while the vehicle is stopped increases.)
When troubleshooting, if the malfunction cannot be identified, the battery might be deteriorated.
Even if stop and start control is prohibited due to the condition of any of the systems listed above, performing the Active Tests allows stop and start control to be performed.
