L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P0867-880: Transmission Fluid Pressure
P0867-880 - Transmission Fluid Pressure
DESCRIPTION
For a description of the hybrid vehicle transmission assembly, P0731.
MONITOR DESCRIPTION
The hybrid vehicle control ECU monitors the hydraulic control system. After DTC P0868 (INF 866/894) is detected, if the hybrid vehicle control ECU continues to apply the line pressure, but the ECU cannot confirm that the line pressure has been applied, the ECU will illuminate the MIL and set a DTC.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK DTC OUTPUT (HV)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
(d) Check if DTCs are output.
Result:
B -- GO TO DTC CHART Hybrid Control System
A -- Continue to next step.
2. CHECK CONNECTOR CONNECTION CONDITION (HYBRID VEHICLE CONTROL ECU CONNECTOR)
(a) Turn the power switch off.
(b) Check the connections of the hybrid vehicle control ECU connectors.
OK:
The connectors are connected securely and there are no contact problems.
NG -- CONNECT SECURELY
OK -- Continue to next step.
3. CHECK CONNECTOR CONNECTION CONDITION (TRANSMISSION WIRE CONNECTOR)
(a) Check the connection of the transmission wire connector.
OK:
The connector is connected securely and there are no contact problems.
NG -- CONNECT SECURELY
OK -- Continue to next step.
4. CHECK CONNECTOR CONNECTION CONDITION (OIL PUMP MOTOR CONTROLLER CONNECTOR)
NOTICE:
Before disconnecting the connectors, confirm that they are properly connected by checking that the locking claws are engaged and that the connectors cannot be pulled out.
(a) Check the connections of the oil pump motor controller connectors.
OK:
The connectors are connected securely and there are no contact problems.
HINT
For connector A, when connecting it, insert it with the locking lever in the raised position. Rotate the lever downward and make sure that the connector is pulled into its socket. When the locking lever is in its fully closed position, a click will be heard as its locking claws engage. After the click is heard, pull up on the connector to confirm that it is properly connected.
NG -- CONNECT SECURELY
OK -- Continue to next step.
5. CHECK FUSIBLE LINK BLOCK ASSEMBLY (OIL PMP)
(a) Check if there is an open circuit in the fusible link (OIL PMP) in the engine room No. 1 junction block.
OK:
There is no open circuit in the fusible link.
NG -- REPLACE FUSIBLE LINK BLOCK ASSEMBLY
OK -- Continue to next step.
6. CHECK HYBRID VEHICLE TRANSMISSION ASSEMBLY (SP SOLENOID)
(a) Disconnect connector E55 from the hybrid vehicle control ECU.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - TRANSMISSION WIRE)
OK -- Continue to next step.
7. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - OIL PUMP MOTOR CONTROLLER)
(a) Turn the power switch off.
(b) Disconnect connector A74 from the hybrid vehicle control ECU.
(c) Disconnect connector A78 from the oil pump motor controller.
(d) Turn the power switch on (IG).
(e) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NOTICE:
Turning the power switch on (IG) with the hybrid vehicle control ECU and oil pump motor controller connectors disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.
(f) Turn the power switch off.
(g) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for open):
Standard resistance (Check for short):
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
8. CHECK RELAY (OIL PMP) P0867
NG -- REPLACE RELAY (OIL PMP) Components
OK -- Continue to next step.
9. CHECK OIL WITH MOTOR PUMP ASSEMBLY P0867
NG -- REPLACE OIL WITH MOTOR PUMP ASSEMBLY Components
OK -- Continue to next step.
10. CHECK OIL PUMP MOTOR CONTROLLER (POWER SOURCE CIRCUIT) P0867
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
11. CLEAR DTC
(a) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
(b) Read and record the DTCs and freeze frame data.
(c) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
(d) Clear DTCs and freeze frame data.
NEXT -- Continue to next step.
12. SIMULATION TEST (OIL PUMP MOTOR)
(a) Turn the power switch on (IG).
(b) Select the following menu items: Powertrain / Hybrid Control / Active Test / Activate the Oil Pump (500rpm), Activate the Oil Pump (1000rpm).
(c) Select the following menu items: All Data / OPM Target Revolution, B2 Oil Pressure, OPM Revolution.
(d) Perform the "Activate the Oil Pump (500rpm)" and "Activate the Oil Pump (1000rpm)" active tests.
OK:
"OPM Target Revolution" and "OPM Revolution" values are almost equal.
NOTICE:
Make sure that the auxiliary battery is not discharged.
NG -- REPLACE OIL WITH MOTOR PUMP ASSEMBLY Components
OK -- Continue to next step.
13. SIMULATION TEST (HYBRID VEHICLE TRANSMISSION ASSEMBLY)
(a) Turn the power switch on (READY).
(b) Select the following menu items: Powertrain / Hybrid Control / Active Test / Control the Shift Position.
(c) Select the following menu items: All Data / B1 Oil Pressure, B2 Oil Pressure, Line Pressure, Line Pressure Solenoid.
(d) Perform the "Control the Shift Position" active test.
(e) Switch the shift position between "Lo" and "Hi" several times using the "Control the Shift Position" active test.
OK:
NOTICE:
Transmission system DTCs may be set if the "Control the Shift Position" active test is canceled before it is completed.
NG -- REPLACE HYBRID VEHICLE TRANSMISSION ASSEMBLY Components
OK -- Continue to next step.
14. CHECK FOR INTERMITTENT PROBLEMS
