DTC Descriptor

DTC B101D XX

- ECU Hardware

Circuit/System Description

The internal fault detection is handled inside the control module. The symptom byte listed in the DTC Descriptor is for engineering reference only.

No external circuit diagnosis is involved.

Conditions for Running the DTC

The module runs the program to detect an internal fault when power up is commanded. The only requirements are voltage and ground. This

program runs even if the voltage is out of the valid operating range.

Conditions for Setting the DTC

The module has detected an internal malfunction.

Action Taken When the DTC Sets

The module refuses all additional inputs.

Conditions for Clearing the DTC

* A current DTC clears when the malfunction is no longer present.

* A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.

Diagnostic Aids

* This DTC may be stored as a history DTC without affecting the operation of the control module.

* Do not replace a control module based only on DTC B101D being set in history with the exception of the following control modules:

- Sensing and Diagnostic Module (SDM)

- Passenger Presence System Module

* If DTC B101D is set as current, replace the appropriate control module.

Circuit/System Verification

Verify that DTC B101D is not set.

and the ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.

Note: Use the J 35616-200 - Test Lamp for this test. If the J 35616-200 - Test Lamp is not available, use a test lamp that measures greater

Circuit/System Description

The fuel rail pressure sensor detects fuel pressure within the fuel rail. The engine control module (ECM) provides a 5 V reference voltage on the 5

V reference circuit and ground on the low reference circuit. The ECM receives a varying signal voltage on the signal circuit.

High pressure fuel is regulated by the high pressure fuel pump actuator, which is a part of the high pressure fuel pump. The high pressure fuel pump

actuator is a solenoid valve. The ECM provides a voltage on the actuator high control circuit and ground on the actuator low control circuit. Both

circuits are controlled through output drivers within the ECM. When deactivated, both drivers are disabled. When activated, the high control circuit

driver energizes the high pressure fuel pump actuator and the low control circuit driver pulse-width modulates (PWM) the low control circuit to

ground.

The high pressure mechanical fuel pump is driven by three lobes on the camshaft. The ECM uses the camshaft and crankshaft position sensor inputs

to synchronize the high pressure fuel pump actuator with the position of each of the camshaft lobes. The ECM regulates fuel pressure by adjusting

the portion of each pump stroke that provides fuel to the rail.

The ECM monitors the fuel rail fuel pressure sensor and the high pressure fuel pump actuator to determine if the commanded and actual pressure

are within a predetermined range, or if the amount of fuel pressure correction exceeds a calibrated pressure.

Conditions for Running the DTC

* DTC P0090, P0091, P0092, P0191, P0192, or P0193 is not set.

* The ignition 1 signal parameter is between 10-18 V.

* The engine start temperature is greater than -48掳C (-54掳F).

* The fuel level is greater than 11 %.

* The deceleration fuel cut-off (DFCO) is inactive.

* The engine speed is greater than 600 RPM once during engine start for greater than 5 s.

* The air bag is not deployed.

* DTCs P0087, P0088, and P0089 run continuously when the above conditions are met for 5 s.

Conditions for Setting the DTC

P0087

The actual fuel rail pressure is 1 MPa (145 psi) less than the desired fuel pressure. The condition exists for greater than 5 s.

P0088

The actual fuel rail pressure is 2 MPa (290 psi) greater than the desired fuel rail pressure. The condition exists for greater than 5 s.

P0089

The high pressure fuel pump actuator command necessary to maintain the desired fuel rail pressure is +/-2 MPa (290 psi) of the command expected

by the controller. The condition exists for greater than 5 s.

Action Taken When the DTC Sets

* DTCs P0087, P0088, and P0089 are Type A DTCs.

* A message center or an indicator displays Reduced Engine Power.

Conditions for Clearing the DTC

DTCs P0087, P0088, and P0089 are Type A DTCs.

Diagnostic Aids

* A condition with the fuel tank fuel pump module or fuel pump flow control module will set these DTCs.

* A skewed fuel rail pressure sensor, or an intermittent condition in the fuel rail pressure sensor circuits may set these DTCs.

* A leaking or restricted fuel injector may set DTC P0089.
