Toyota Corolla Cross: On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. FUEL PUMP ASSEMBLY OPERATION
(a) Check fuel pressure.
(1) Connect the GTS to the DLC3.
(2) Start the engine.
(3) Turn the GTS on.
(4) Enter the following menus: Powertrain / Engine / Active Test / Control the Target Fuel Pressure Offset / Fuel Pressure (High).
Powertrain > Engine > Active Test
Active Test Display |
Control the Target Fuel Pressure Offset |
Data List Display |
Fuel Pressure (High) |
(5) Check that the fuel pressure fluctuates when the target fuel pressure changes.
HINT:
The target fuel pressure operation decreases the target fuel pressure by 12.5% or increases the target fuel pressure by 24.8%.
If the result is not as specified, replace the fuel pump assembly or fuel pressure sensor.
(b) Check operating sound.
(1) Start the engine.
(2) Using a sound scope, check the operating sound of the fuel pump assembly.
If no sound can be heard, check the fuel pump assembly, wire harness and ECM.
(3) Stop the engine.

DTC SUMMARY MALFUNCTION DESCRIPTION This DTC indicates that current does not flow as commanded due to a generator output circuit malfunction. The cause of this malfunction may be one of the following:
Area Main Malfunction Description
Inside of inverter
Inverter with convert
MONITOR DESCRIPTION The ECM continuously monitors its main CPU and monitor IC. This self-check ensures that the ECM is functioning properly. If outputs from main CPU and monitor IC are different and deviate from the standard, the ECM will illuminate the MIL and store this DTC.
DTC No. Detect
