DIAGNOSTIC RESPONSE:

DNS, Lock in current range

 

CIRCUIT DESCRIPTION:

The speed sensors are devices which convert mechanical motion to an electrical signal. This test detects a turbine speed sensor circuit short to battery, ground, or open.

 

ACTION TAKEN WHEN THE DTC SETS:

When DTC P0715 is active, the following conditions occur:

1 If the DTC sets while shift not in process, remains in current range.

2 If the DTC sets while shift is in process, complete shift and lock in that range.

3 There is no response to shift selector requests.

4 DTC is stored in TCM history.

5 The CHECK TRANS light illuminates.

6 The TCM inhibits TCC engagement.

7 The TCM freezes shift adapts.

 

CONDITIONS FOR CLEARING THE DTC:

Use the diagnostic tool to clear the DTC from the TCM history.The TCM automatically clears the DTC from the TCM history if the vehicle completes 40 warm-up cycles without the DTC recurring.

 

DIAGNOSTIC AIDS:

DTC P0715 may be caused by:

1 W120 and/or W180 shorted to another wire in chassis harness or to ground.

2 W120 and/or W180 high resistance or open circuit.

3 Broken or defective connector assemblies allowing pushed back pins to short together.

4 Unlocked connectors, missing seal plugs allowing moisture in connectors.

5 Fatigued wires at speed sensor connectors (broken strands).

6 Incorrect pin crimps or expanded terminals.

7 Defective turbine shaft speed sensor.

8Defective TCM.

9 Damaged rotating clutch drum.

10 Wire pair not twisted or not sufficiently twisted.

 

NOTE:Confirm that the speed sensor wiring consists of twisted pairs at the rate of 12 to 16 twists per 300 mm. These twists must extend the entire length of the wiring harness to within at least 50 mm of the speed sensor connector.

 

NOTE: The OEM Transmission warranty, or the extended coverage for parts and labor, does not cover transmission or vehicle damage caused by drivelines that do not meet the OEM Transmission specifications.

QSK60 G CM2358 Engine Voltage Above Normal or Shorted to High Source

Here is the instruction show you guide on how to repair post-oil filter pressure sensor circuit – voltage above normal or shorted to high source.

 

What You Need?

Cummings Insite 9.0.1

Cummings inline6 diagnostic adapter

 

 

Code:

Fault Code: 1377
PID: S151
SPN: 3549
FMI: 3/3
LAMP: Maintenance
SRT:

 

Reason:

High signal voltage detected at the oil filter outlet pressure circuit.

 

Effect:

None on performance.

 

Circuit Description

The engine control module (ECM) provides a 5 volt supply to the oil filter intake pressure sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The oil filter intake pressure sensor provides a signal to the ECM on the oil filter intake pressure sensor signal circuit. This sensor signal voltage changes, based on the pressure before the oil filters. The ECM will detect a low signal voltage at operating conditions when the oil pressure may be slightly lower. The ECM will detect a high signal voltage during high engine speeds or operating conditions when the oil temperature is low.

 

Component Location

The post-filter oil pressure sensor is located between the oil filter and the oil cooler.

 

Conditions for Running the Diagnostics

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

 

Conditions for Setting the Fault Codes

The Engine Control Module (ECM) detected the engine oil filter intake pressure signal voltage was out of range high.

 

Action Taken When the Fault Code is Active

The ECM illuminates the white MAINTENANCE lamp or flashes the amber CHECK ENGINE lamp, indicating a maintenance condition, immediately after the diagnostic runs and fails.

Conditions for Clearing the Fault Code

To validate the repair, start the engine and let it idle for 1 minute.

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

 

Shop Talk

Possible causes of this fault code include:

Open return circuit in the harness, connectors, or sensor

Signal circuit shorted to sensor supply or battery voltage

Note : This test should be performed only if directed here by a diagnostic procedure.

Detroit Diesel GHG17 Heavy Duty Mechanical Cylinder Compression Test

Perform the following steps for a mechanical compression test on a GHG17Heavy Duty DD Platform Engine:

Jake Brake ® /piston

Valve lash/valve train damage

Camshaft timing

Cylinder liner/ring damage

Fuel injector hold-downs

Blown cylinder head gasket

Cracked cylinder liner or cylinder head

Valve or seat damage

 

Note : First perform the Relative Cylinder Compression Test using DiagnosticLink.. If results indicate a weak cylinder, perform this mechanical compression test.

1 The valve lash needs to be checked before the mechanical compression test is performed.and adjust as necessary, if no adjustment is needed continue to step 2.

2 Run the engine and bring the engine coolant temperature to normal operating range, 88 to 96°C (190 to 205°F).

 

3 Disconnect the batteries and plug the batteries into a battery charger. Refer to OEM procedures.

4 Remove rocker cover.

5 Remove the fuel injector harness.

6 Disconnect electrical contacts at the fuel injectors.

7 Disconnect the two wiring terminals going to the Jake Brake ® solenoids.

8 Disconnect the 14-pin fuel injector harness connector.

9 Remove the spring clip holding the fuel injector harness connectors to camshaft frame.

10 Remove the fuel injector wiring harness(es).

11 Remove the high pressure fuel line from all cylinders.

12 Remove all fuel injectors.

13 Remove excess fuel from cylinders using a vacuum pump.

14 Install the compression test adapter (J-47411) into the fuel injector bore in the cylinder head.

15 Install the fuel injector hold-down clamp and bolt. Torque the bolt to 20 N·m (14 lb·ft) + 90 degrees.

16 Install the fuel rail plug (J-48704 or W470589129100).

17 Install a hold-down bolt onto the Jake-Brake ® solenoid and snug the bolt.

18 Reconnect the batteries; keep the battery charger plugged into the batteries.

Note : Verify that the battery voltage does not go low enough to affect engine cranking speed. If the cranking speed is affected, then the results will be inaccurate. A battery charger will help to maintain an acceptable battery voltage.

19 Using DiagnosticLink start the Mechanical Compression Test routine, this will disable fuel from the Quantity Control Valve.

20 With the batteries fully charged, crank the engine over five compression strokes at 150 rpm or greater using the starter motor. Record the compression reading on the gauge.

21 At normal operating temperature, the compression reading should be no less than 28 bar (400 psi). If compression readings are below specifications, repeat step 13 with a different gauge to be certain of the reading.

Note : Fuel injector hold-down bolts are a one-time use item.

22 Remove the fuel injector hold-down clamps. Discard the hold-down bolt and remove the compression test adaptors.

23 Repeat steps for all suspect cylinders.

24 Repair engine as necessary.
