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.

Preparations:

DDDL 8.18 2023

Nexiq USB Link 2 Adapter

 

Procedures:

Check as follows:

1 Is MCM fault code SPN 1663 /FMI 7 present?

1aYes; troubleshoot this code first.

1b No; Go to step 2.

 

2 Was the CPC recently programmed?

2a Yes; check for proper CPC parameter settings. Refer to section “Optimized Idle” of the A&I Manual (See table below).

2b No; Go to step 3.

 

3 Using DiagnosticLink, verify the operation of the Optimized Idle Safety Loop and the Vehicle Speed Sensor (VSS). Under Instrumentation, go to the Chart tab and select the following on the chart:

 

  • DSL: Parking Brake
  • DSL: Hood Tilt Switch
  • DSL: Neutral Switch
  • ASL: Road Speed

Cycle each switch and monitor their functionality. Monitor the Road Speed; it should read zero when the vehicle is stationary.

Was a fault with either the Optimized Idle Safety Loop or VSS found?

3a Yes; repair as necessary.

3b No; Go to step 4.

 

4 Is the vehicle equipped with an Auxiliary Power Unit (APU) or ParkSmart?

4a Yes; vehicles with an APU or ParkSmart may not use Optimized Idle to control the cab temperatures. If this is the customer’s complaint, refer to the APU or ParkSmart operation instructions.

4b No; Go to step 5.

 

5 Check the Optimized Idle Thermostat settings; Refer to section “Thermostat Operation” of the Optimized Idle User Manual (DDC-SVC-MAN-0019) . Is the Optimized Idle Thermostat properly configured?

5a Yes; install a test CPC. Go to step 6.

5b No; Refer to section “Thermostat Operation” of the Optimized Idle User Manual (DDC-SVC-MAN-0019) . Verify repair.

 

6 Will Optimized Idle work correctly with the test CPC?

6a Yes; replace the CPC.

6b No; Go to step 7.

 

7 Set the Optimized Idle Thermostat mode to cool the cab and put the vehicle on Optimized Idle mode. Using a heat gun, apply heat to the Optimized Idle Thermostat Skin Temperature sensor; refer to OEM literature for sensor location. Did Optimized Idle start the engine to cool the cab?

7a Yes; Refer to section “Optimized Idle” of the A&I Manual (See table below) for proper Optimized Idle parameter configuration

7b No; Go to step 8.

 

8.Monitor the Optimized Idle Thermostat temperature reading while applying heat to the sensor. Is the reading on the Thermostat display accurate?

8a Yes; replace the Optimized Idle Thermostat.

8b No; Go to step 9.

 

9 Disconnect the Optimized Idle Thermostat electrical connector and measure the resistance between pin 3 of the Optimized Idle Thermostat connector, harness side and the sensor ground circuit of the Skin Temperature sensor harness side connector. Is the resistance less than five ohms?

9a Yes; Go to step 10.

9b No; repair the circuit.

 

10 Measure the resistance between pin 1 of the Optimized Idle Thermostat connector, harness side and the sensor signal circuit of the Skin Temperature sensor harness side connector. Is the resistance less than five ohms?

10a Yes; replace the Optimized Idle Thermostat.

10b No; repair the circuit.

Perkins 800 Series Industrial Engine Fuel Injector Test

Perform the following procedures in order to determine if a fuel injector does not work correctly.
Bench test the fuel injectors at a temperature of 18° to 20 °C (64° to 70 °F).

What you Need?

Perkins EST 2023A Diagnostic Software

Perkins Communication Adapter 3

 

Procedures:

1 Run the engine at low idle.
2 Loosen the connection for the high pressure fuel line (1) at the fuel injector on No. 1 cylinder. Do not loosen the nut more than half of a turn. Listen for the low idle to decrease or become rough. Tighten the nut for the fuel supply line on No. 1 cylinder.

Perform this test on each cylinder.
3The fuel injector is faulty when the nut for the fuel supply line is loosened and the following events occur:
• The engine rpm does not decrease.
• The engine does not idle roughly.

 

4 Remove the fuel injector for additional testing.
Note: If leakage occurs at the nut for the fuel supply line, make sure that the fuel supply line and the nut are correctly aligned with the inlet connection of fuel injector. Do not tighten the nut for the fuel supply line on the high pressure fuel line more than the recommended torque. If the nut is tightened more, the fuel line may become restricted or the threads of the fuel injector and the nut may be damaged.

Cleaning of the fuel injectors
Before a fuel injector is tested, remove any loose carbon from the tip of the fuel injector. Do not use abrasive material or a wire brush in order to clean the nozzle.
The fuel injector is not a serviceable part.

Disassembling or adjusting the nozzle will violate the standards for emissions.
Note: Extra care should be used in handling the fuel injector in order to prevent damage to the nozzle tip.
A scratch or a burr could cause needle leakage or spray distortion. Dirt in the orifices of the nozzle tip can damage engine components. Dirt can also distort the spray pattern of the nozzle.
