DATA LIST / ACTIVE TEST

DATA LIST

HINT:

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.

NOTICE:

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.

(a) According to the display on the GTS, read the Data List.

*1: Regarding Auxiliary 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 auxiliary battery condition (charge/discharge condition) to protect the auxiliary battery and to ensure stable engine restarting performance.

The auxiliary battery charge/discharge condition is determined from the integrated current value calculated from the auxiliary battery sensor signal. The integrated current value is obtained by multiplying the current (Ampere) detected from the auxiliary battery sensor by the time (seconds), and it is expressed in a unit A-sec.

HINT:

Example: Integrated current of -3110 A-sec corresponds to a load where current of 10 A flows out from the auxiliary battery for 311 seconds.

The integrated current value can be read by checking the Data List item "Integrated Current" using GTS. The item "Stop&Start Operating Permission (Integrated Current)" shows the permission status of stop and start control (OK or NG) and is judged from the "Integrated Current" value.

Negative integrated current represents auxiliary battery discharge, and positive represents auxiliary battery charge. In other words, the "Integrated Current" value of the Data List item will decrease from the present value when the auxiliary battery is discharged, and the value will increase when the auxiliary 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 auxiliary battery might not be able to start the engine. The threshold varies according to the auxiliary battery fluid temperature.

Integrated Current Condition 1:

When "Status of Auxiliary Battery Charge Control" is Charge Control Coordination Mode, Stop and Start Standalone Mode or Low Temperature Mode:

Stop and Start System Operation (for Condition 1)
  • Phase A (previous trip integrated current storage):

    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 (stop and start control permitted):

    Stop and start control is permitted to stop the engine until the integrated current reaches -4838 A-sec or less.

  • Phase C (charging):

    When the integrated current has dropped to -4838 A-sec or less, stop and start control is prohibited from stopping the engine until the current reaches -3974 A-sec.

  • Phase D (stop and start control permitted):

    Stop and start control is permitted to stop the engine until the integrated current reaches -4838 A-sec or less.

Integrated Current Condition 2:

When "Status of Auxiliary Battery Charge Control" is Stop and Start Restriction Mode or Temperature High/Low Mode:

Stop and Start System Operation (for Condition 2)
  • Phase A (previous trip integrated current storage):

    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 (stop and start control permitted):

    Stop and start control is permitted to stop the engine until the integrated current reaches -864 A-sec or less.

  • Phase C (charging):

    When the integrated current has dropped to -864 A-sec or less, stop and start control is prohibited from stopping the engine until the current reaches 0 A-sec.

  • Phase D (stop and start control permitted):

    Stop and start control is permitted to stop the engine until the integrated current reaches -864 A-sec or less.

HINT:

  • 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.

ACTIVE TEST

HINT:

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.

(a) Perform the Active Test by referring to the table below.

HINT:

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.
