NOTICE:

If the Data List item "Stop&Start Operating Permission (Power Management)" is "NG" even after correcting a certain problem using the diagnostic troubleshooting procedures, the problem may be due to the battery charge amount being temporarily low or the battery may be deteriorated. However, there may be multiple overlapping conditions which are causing system operation to be prohibited, so make sure to always confirm all the diagnostic troubleshooting procedures.

HINT:

If the Data List item "Integrated Current" is 0 A-sec or higher, it is not necessary to perform initialization.


·

When the battery state sensor assembly current value is normal, recharge or replace the battery

·

When the electrical load is large, a large amount of electrical discharge occurs. As a result, the integrated current value (battery charge amount) tends to drop causing operation to be prohibited.

Stop&Start Operating Permission (Minimum Voltage (Starter Solenoid Engagement)) Permission of stop and start control based on minimum voltage during starter solenoid engagement NG / OK OK: Minimum voltage when starter begins operation is equal to the threshold or higher If both Minimum Voltage (Starter Solenoid Engagement) condition and Minimum Voltage (Cranking) condition are OK, stop and start control is permitted
Stop&Start Operating Permission (Minimum Voltage (Cranking)) Permission of stop and start control based on minimum voltage during cranking NG / OK OK: Minimum voltage when cranking is equal to the threshold or higher If both Minimum Voltage (Starter Solenoid Engagement) condition and Minimum Voltage (Cranking) condition are OK, stop and start control is permitted.
Permission Criteria (Specified Battery):
Tester Display Minimum Voltage (Starter Solenoid Engagement) Minimum Voltage (Cranking)
Stop&Start Operating Permission (Minimum Voltage (Starter Solenoid Engagement)) 8.50 V or higher -
Stop&Start Operating Permission (Minimum Voltage (Cranking)) - 8.30 V or higher


Permission Criteria (Non-specified Battery):
Tester Display Minimum Voltage (Starter Solenoid Engagement) Minimum Voltage (Cranking)
Stop&Start Operating Permission (Minimum Voltage (Starter Solenoid Engagement)) 8.92 V or higher -
Stop&Start Operating Permission (Minimum Voltage (Cranking)) - 8.92 V or higher



m.

Replace the battery in the following situations.

"Stop&Start Operating Permission (Minimum Voltage (Starter Solenoid Engagement) and Minimum Voltage (Cranking))" is less than the threshold.

HINT:

When the battery temperature is low, operation may not be permitted even if the battery is not deteriorated.

In this case, perform the inspection when the battery temperature is not low. (A fluid temperature of 20°C or higher)
