L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P0867-880: Transmission Fluid Pressure
DTC P0867-880 - Transmission Fluid Pressure
DESCRIPTION
For a description of the hybrid vehicle transmission assembly, P0731-871.
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 intelligent tester or Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Select the following menu items:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / HV ECU / DTC INFO / CURRENT CODES.
(2) Techstream - Select: Powertrain / Hybrid Control / Trouble Codes.
(d) Check if DTCs are output.
Result:
B -- GO TO DTC CHART
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)
NOTE: Before disconnecting the connectors, confirm that they are properly connected by checking that the locking claws are engaged and that the connectors do not pull 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 :
NOTE: 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) P0867-876
NG -- REPLACE RELAY (OIL PMP)
OK -- Continue to next step.
9. CHECK HYBRID VEHICLE TRANSMISSION ASSEMBLY (OIL PUMP MOTOR) P0867-876
NG -- REPLACE HYBRID VEHICLE TRANSMISSION ASSEMBLY
OK -- Continue to next step.
10. CHECK OIL PUMP MOTOR CONTROLLER (POWER SOURCE CIRCUIT) P0867-876
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
11. CLEAR DTC
