Caterpillar C9 Engine PTO Engine Shutdown Switch Voltage Low

Caterpillar C9 engine PID 186-4 PTO engine shutdown switch voltage low solution.

Caterpillar C9 Engine

Caterpillar CAT ET 2023C

CAT Comm Adapter 3

 

A short to ground exists in the wiring for the PTO engine shutdown switch. The parameter “PTO Engine Shutdown Switch” must be programmed to “J1/P1:7” or “J1/P1:23”.

 

 

If the vehicle speed is not equal to zero, or if there are active vehicle speed faults, the engine will go to low idle. The engine will not shut down when the vehicle speed falls to zero. When the PTO engine shutdown switch is pressed, a 186-14 will become active. The code will stay active until the engine shuts down. When the engine shuts down, the code will be loggged.

 

Possible Causes:

1) ECM Connection/Harness

2) PTO Shutdown Switch Failure

3) ECM Failure

4) Wiring between PTO shutdown switch and ECM

QSK CM2358 Fault Code 123 Pressure Sensor Circuit Voltage Low Error

QSK CM2358 Fault Code 123 Intake Manifold 1 Pressure Sensor Circuit – Voltage Below Normal or Shorted to Low Source.Low signal voltage or open circuit detected in the intake manifold pressure sensor circuit.Possible reduced engine performance.

Insite 8.9.2/8.7 Diagnostic for Cummings Engine

Cummings INLINE 6 Diagnostic Adapter for Heavy Duty Truck High Quality

 

Circuit Description

The engine control module (ECM) provides a 5 volt supply to the intake manifold pressure sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The intake manifold pressure sensor provides a signal to the ECM on the intake manifold pressure sensor signal circuit. This sensor signal voltage changes based on the pressure in the intake manifold.

 

Component Location

The intake manifold pressure sensor 1 is located in intake manifold 1.

Conditions for Running the Diagnostics

This diagnostic runs continuously when the keyswitch is in the ON position.

 

Conditions for Setting the Fault Codes

The Engine Control Module (ECM) detected the intake manifold pressure sensor signal voltage is out of range low.

 

Action Taken When the Fault Code is Active

The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails. A default value of the intake manifold pressure reading is used.

 

Conditions for Clearing the Fault Code

Turn the keyswitch OFF. Allow the ECM to completely power down and turn the keyswitch ON.

The fault code status displayed by the recommended electronic service tool or equivalent will change to INACTIVE immediately after the diagnostic runs and passes.

The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.

The “Reset All Faults” command in the recommended electronic service tool or equivalent can be used to clear active and inactive faults.

 

Shop Talk

The intake manifold pressure sensor shares supply and return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Before troubleshooting Fault Code 123, check for multiple faults.

 

Possible causes of this fault code include:

Signal circuit open or shorted to ground in the engine wiring harness or sensor.

Supply wire open or shorted to ground.

A malfunctioning intake manifold pressure sensor

PCC1302 PowerCommand Code 781 – ECM CAN Datalink Has Failed

Logic:
Communication between the engine control module (ECM) and the generator set control is severed.

PCC1302 Command

Preparations:

2023 Cummings InPower 14.5 Pro

PowerCommand Diagnostic 9 Pin Adapter Cable for InPower

 

Possible Causes:
1. The Engine ECM has lost power or failed
2. The CAN datalink has failed

Diagnosis and Repair:
1. The Engine ECM has lost power or failed
a. Check the wiring from the base board.
b. Keyswitch control relay is a normally open relay. Ensure that B+ is available at the relay input, then measure the voltage output. If there is a B+ at both the input and
output of the Keyswitch control relay, the relay is not faulty. If B+ is noted at the input but not at the output of the Keyswitch control relay, replace the relay.
c. Connect to the engine ECM with InPower and/or Insite, to verify that the ECM is functioning properly and is communicating with the CAN-LINK network. Refer to the
engine service manual for ECM troubleshooting procedures, if the ECM is faulty,replace.
2. The CAN datalink has failed
a. There is a defective datalink harness connection, or open circuit; inspect the datalink harness and connector pins. Also check the shield ground connection.

b. Check the terminating resistors. With connector disconnected from the base board and the engine datalink connection disconnected from the ECM control, measure
resistance between pins (60 ohms is satisfactory). If the resistance is not 60 ohms,check the terminating resistors. Each of the two terminating resistors should be 120
ohms, replace if not 120 ohms.

Procedures:

(1) Lift up the cylinder head assembly, and remove the cylinder head assembly from the crankcase.
Note: If the cylinder head assembly cannot be removed due to crimping of the cylinder head gasket, tap the thick area on the side of the cylinder head using a plastic hammer to give a shock.
Do not lift up the crankcase by yourself. Use a crane or lift it up by two persons.
(2) Remove the cylinder head gasket.
Note: If there is a cylinder head problem, check the bolts for tightness with a torque wrench before removing the cylinder head bolts.
