P062714 | Fuel Pump Control Duty Ratio |
MONITOR DESCRIPTION
The ECM monitors the fuel pump control ECU operation signals.
When the output duty ratio of the operation signal from the ECM is 3 to 65% and the FPC terminal voltage is a certain value or less for 3 seconds or more, the ECM stores a DTC.

CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. | CHECK HARNESS AND CONNECTOR (POWER SOURCE OF FUEL PUMP CONTROL ECU) |
(a) Disconnect the fuel pump control ECU connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
NG |
![]() | GO TO STEP 4 |
|
2. | INSPECT ECM (FPC TERMINAL) |
(a) Disconnect the fuel pump control ECU connector.
(b) Operate the fuel pump control ECU using the Active Test function and measure the resistance according to the value(s) in the table below.

Fuel Pump Single Phase Energization |
Standard Resistance:
Tester Connection | GTS Operation | Specified Condition |
---|---|---|
O2-2 (FPC) - Body ground | Before Active Test → During Active Test | Before Active Test: Resistance is stable → During Active Test: Resistance fluctuates* |
HINT:
*: Using the Active Test, duty control of the transistors in the ECM will be performed. Due to the duty control, resistance of the FPC terminal will be unstable during the Active Test. If the resistance is stable before the Active Test and fluctuates while performing the Active Test, it can be determined that the transistor is operating. If the transistor does not operate during the Active Test, the ECM may be malfunctioning.

The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal collisions.
In addition, the pretensioners operate when a side collision or a rollover accident is detected. The pretensioners operate differently depending on what types of air bags are equipped. For more details about the seat belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria.
