DESCRIPTION The hybrid vehicle control ECU monitors the system internal operation, it will store a DTC and perform fail-safe control if it detects the following malfunction.
CONFIRMATION DRIVING PATTERN HINT: After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure. Click here
WIRING DIAGRAM CAUTION / NOTICE / HINT CAUTION:
NOTICE: After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work. Click here PROCEDURE
(a) Connect the Techstream to the DLC3. (b) Turn the power switch on (IG). (c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. (d) Check for DTCs. Powertrain > Hybrid Control > Trouble Codes
(e) Turn the power switch off.
(a) Connect the Techstream to the DLC3. (b) Turn the power switch on (IG). (c) Enter the following menus: Powertrain / Hybrid Control / Data List / Hybrid Battery Current. Powertrain > Hybrid Control > Data List
(d) Read the Data List.
(e) Turn the power switch off.
CAUTION: Be sure to wear insulated gloves. (a) Check that the service plug grip is not installed. NOTICE: After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction. (b) Remove the No. 1 HV battery cover panel RH. Click here
(d) Remove the No. 1 hybrid battery exhaust duct. Click here (e) Disconnect the y6 battery voltage sensor connector. NOTICE: Before disconnecting the connector, check that it is not loose or disconnected.
(g) Reconnect the y6 battery voltage sensor connector. (h) Install the No. 1 hybrid battery exhaust duct. (i) Reconnect the y7 battery current sensor connector. (j) Install the No. 1 HV battery cover panel RH.
CAUTION: Be sure to wear insulated gloves. (a) Check that the service plug grip is not installed. NOTICE: After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction. (b) Remove the No. 1 hybrid battery exhaust duct. Click here (c) Connect the cable to the negative (-) auxiliary battery terminal. (d) Turn the power switch on (IG).
(g) Compare the measured values of the IB0 terminal voltage and VIB terminal voltage using the following formula:
(h) Turn the power switch off. (i) Disconnect the cable from the negative (-) auxiliary battery terminal. (j) Install the No. 1 hybrid battery exhaust duct. HINT: When the power switch is on (IG) the actual current will be approximately 0 A. The following graph shows the relation of the actual output voltage of the battery current sensor terminal IB0 and actual current used for DTC judgment.
