Fault Code Retrieval/Clearing

General Information | Fault Code Retrieval/Clearing

Retrieving Fault Codes Manually

Retrieve fault codes by enabling the system’s self-diagnostic mode.

Note: You can also use a PC- based service tool, such as

ServiceRanger to retrieve fault codes.

1. Place the shift lever in neutral.

2. Set the parking brake.

3. Turn key on with engine off.

Note: If the engine is already running, you may still

retrieve codes; however, do not engage the starter if the engine stalls.

4. To Retrieve Active Codes: Key on. Turn key off on 2 times within five seconds ending with the key on. After 5 seconds, the Service light begins flashing two-digit fault codes. If no faults are active, the service light will flash code 25 (no codes). This is also the procedure to enter, See “Product Diagnostic (PD) Mode” on page 11. for details.

Note: An “88” may show up in the dash at key on,

which is a normal power-up test of the display.

Retrieving Fault Codes with ServiceRanger

This section determines if the TECU is communicating on the vehicle's J1939 data link and if the component has set any fault codes. Proper system operation requires the TECU to communicate with other ECUs on the vehicle's J1939 data link.

Note: This procedure requires ServiceRanger 3.0 or later

and an approved RP1210A communications adapter that supports J1939 communications.

Detecting Components

1. Connect the service PC to the 39 diagnostic port connector with

J19 RP1210A communications adapter.

2. Start the ServiceRanger program and verify

connection has J1939 data link.

Product Diagnostic (PD) Mode

PD Mode is used to help diagnose Inactive codes that may have been set during normal driving. This diagnostic mode increases the sensitivity of the fault sensing capability

This procedure tests loose, degraded and intermittent connections. Use the Active Fault Isolation Procedure to guide you to the wiring and connectors that are associated with the Inactive fault codes. Flex the wiring harness and connectors and attempt to recreate the fault after activating PD Mode.

PD Mode is only to be used by a trained service technician in an authorized dealer.

General Information | Product Diagnostic (PD) Mode

If the fault is detected during PD Mode the gear dis-

• play will display the active fault. The warning to will only sound will stop when the fault is Inactive. The faul stay in the gear display until the system is powered down.

Electrical Pretest | Electrical Pretest Procedures

Electrical Pretest

Overview

The pretest does not relate to any specific fault code, but must be completed before performing Fault Code Isolation table procedures. The pretest verifies the batteries are fully charged.

All Generation 3 products require the OEM to supply power to the Electronic Control Unit (ECU).

Detection

There is no detection process specifically for the basic electrical supply; however, failures of this type are generally detected by the transmission or driver as some other type of fault code or symptom.

Fallback

There is no fallback for the electrical pretest; however, it may affect other systems.

TRTS0930

Possible Causes

The pretest can be used for:

• Low batteries

• Starter/Battery connections

• Main power harness to the Transmission Co

ntrol Unit (TECU)

Additional Tools

• Basic hand tools

• Eaton Test Adapter Kit

• Digital Volt/Ohm meter

• Troubleshooting Guide

• Battery Load tester

• ServiceRanger a PC-based service tool

J1587: MID130 PID 231 FMI 8, 11 J1939: SA 3 SPN751 FMI 8, 11

Overview

This fault indicates communication has been lost, or does not correspond with the neutral request input from the J1939 Shift Device.

When troubleshooting an Inactive code, See “Product Diagnostic (PD) Mode” on page 11.

Detection

Starting at key on and throughout operation, the Transmission Electronic Control Unit (TECU) constantly monitors communication with the J1939 Shift Device. If a neutral request from the J1939 Shift Device does not match the neutral signal or is not received from the J1939 Shift Device, Fault Code 13 is set.

TRTS0930

Fallback

This fault causes a downshift-only fallback. Once the transmission re-engages the start gear, there will be no upshifts as long as the code is active.

Possible Causes

This fault code can be caused by the following:

Overview

This fault code indicates a possible failure of the Park Pawl Position Sensor or OEM circuit. The sensor is a 4 wire dual hall effect device. When troubleshooting an Inactive code See “Product Diagnostic (PD) Mode” on page 11.

Detection

Starting at key on and throughout operation the Transmission Electronic Control Unit (TECU) constantly monitors the signal from the Park Pawl Position Sensor. The transmission monitors both sensor signals, if one signal to the TECU is out of range the code will set.

Fallback

This fault code will cause the transmission to be stuck in the last known selected position. If the code comes active while in gear, the transmission will a down shift only fallback mode. The transmission will re-engage the start gear when returned to a stop, but will not upshift as long as the code is Active.

Fault Code 15 - HIL Shift Device Configuration

J1587: MID 130 SID 18 FMI 9 J1939: SA 3 SPN 751 FMI 9

Overview

Controller Area Network (CAN) is a high-speed twisted pair 500K proprietary data link with one 120 ohm resistor at each end of the link. The Transmission Electronic Control Unit (TECU) is connected to the CAN data link at the 38-way connector. This link is used to transmit information to the TECU as well as communicate or receive data from the other modules on the network like the HIL Shift Device. See “Product Diagnostic (PD) Mode” on page 11.

Detection

Fault Code 15 is set when the TECU fails to receive Shift Device data for 5 continuous seconds, and it is still communicating with other modules on CAN.

TRTS0930

Fallback

This fault causes a downshift only fallback while moving. Once the transmission re-engages the start gear, there will be no upshifts as long as the code is active. If the code is active during power-up a flashing F will appear on the gear display and the TECU will not engage a gear.

Possible Causes

This fault code can be caused by any of the following:

• CAN data link

• HIL Shift Device

Fault Code 16 - High Integrity Link (HIL)

J1587: MID 130 SID 248 FMI 2 J1939: SA 3 SPN 625 FMI 2

Overview

This fault code indicates the Transmission Electronic Control Unit (TECU) is unable to communicate with the Push Button Shift Control.

Detection

Starting at key-on and throughout operation, the TECU constantly monitors the communication with the Push Button Shift Control. If a communication fault occurs for more than 5 seconds, Fault Code 16 is set.

Fallback

This fault causes a downshift only fallback while moving. Once the transmission re-engages the start gear, there will be no upshifts as long as the code is active. If the code is active during power-up a flashing F will appear on the gear display and the TECU will not engage a gear.

TRTS0930

Possible Causes

This fault code can be caused by any of the following:

• Vehicle Harness

• TECU

• Push Button Shift Control

• Charging system

• Low batteries

• Corroded or loose power supply to TECU

Fault Code 17 - Start Enable Relay (SER) Circuit

J1587: MID 130 SID 237 FMI 3, 4 J1939: SA 3 SPN 629 FMI 3, 4

Overview

This fault code indicates an electrical failure of the relay that allows the engine to start after startup conditions are met.

When troubleshooting an Inactive code See “Product Diagnostic (PD) Mode” on page 11.

Detection

Starting at key-on and throughout operation, the Transmission Electronic Control Unit (TECU) constantly measures the circuit. A failure mode of short to battery, short to ground or open circuit is detected.

Fallback

The start enable relay has no fallback; however, if the failure occurred before the engine was started, it is possible the engine will not start.

Fault Code 21 - Auto Neutral Park Brake Switch | Fault Isolation Procedures

Fault Code 21 - Auto Neutral Park Brake Switch

J1587: MID 130 PID 254 FMI 14 J1939: SA 3 SPN 70 FMI 14

Overview

An auto neutral feature is provided with this transmission which forces the transmission into neutral in all instances when the parking brake is applied. The OEM installs a normally closed T pressure switch into the existing air line to the parking brake valve. The pressure switch output and return wires are connected to the vehicle interface transmission Electronic Control Unit (TECU) connector. Consult OEM for switch location.

This fault code indicates a failure of the switch that reports engagement of the park brake. When troubleshooting an Inactive code See “Product Diagnostic (PD) Mode” on page 11.

Detection

Fault Code 21 is set if the switch indicates the park brake is set while the truck is moving for more than 5 seconds, or if the switch state doesn't match the state broadcast on J1939, or if the switch is unstable for more than 5 seconds.

TRTS0930

Fallback

Remote throttle is disabled, and auto neutral may not work.

Possible Causes

This fault code can be caused by any of the following:

• Park brake switch

• Park brake wiring

• TECU

• Park brake hardware not installed

• J1939 reporting error

Fault Code 22 - ABS CAN Message Fault

J1587: MID 130 SID 254 FMI 9, 14 J1939: SA 3 SPN 563 FMI 9, 14

Overview

J1939 is a high-speed twisted pair 250K baud data link with one 120 ohm resistor at each end of the link. The Transmission Electronic Control Unit (TECU) is connected to the J1939 data link at the 38-way vehicle connector. This link is used to transmit information to the TECU as well as communicate or receive data from the other modules on the network like the ABS module. When troubleshooting an Inactive code See “Product Diagnostic (PD) Mode” on page 11.

Detection

Fault Code 22 is detected if J1939 communication from the ABS is lost for 5 seconds and other devices are present on J1939.

TRTS0930

Fallback

No Fallback mode; however, Hill Start Aid (HSA) will not function, and the system may attempt a shift during wheel slip events.

Possible Causes

This fault code can be caused by any of the following:

• J1939 datalink

• ABS module

• ABS module does not support HSA or is no conf

igured with HSA

T

RTS0930

Overview

This fault code indicates the clutch is not performing as expected. The transmission controller detected excessive clutch slip.

Detection

When the transmission is in gear and the clutch is fully engaged, engine speed and input shaft speed are compared. If the engine speed is significantly different from the input shaft speed for a period of one to two seconds, the fault code is set.

Clutch Slip Testing

Note: It is recommended that the pilot bearing be replaced

whenever the clutch is replaced.

Note: Refer to Installation Guide TRIG1110 for a list of rec-

ommended pilot bearings.

Note: Secondary clutch failures resulting from conditions

such as pilot bearing failures, excessive torsional vibration, or clutch abuse, are not covered under warranty.

Note: Record Vehicle Performance Analysis every time a

clutch is replaced.

Fallback

This fault causes a downshift only fallback. Once the vehicle is stopped, starting gear and reverse gear can be engaged; however, the fault will clear at power down. Upshifts will be allowed until the fault is detected again.

Possible Causes

This fault code can be caused by any of the following:

• Worn or damaged clutch

• Clutch abuse

• Low clutch torque

• Contaminated clutch disks

Additional Tools

• Clutch jack

J1587: MID 130 SID 55 FMI 7, 13 J1939: SA 3 SPN 788 FMI 7, 13

TRTS0930

Overview

The fault code indicates that the clutch has not disengaged as expected.

Detection

Starting at key on and throughout operation, the Transmission Electronic Control Unit (TECU) constantly measures engine RPM and idle torque from the engine. If the engine speed falls significantly below idle or engine torque rises significantly above idle torque upon engaging a start gear, the fault is set. If the vehicle is brought to a stop when in gear and engine speed falls significantly below idle, the fault is set.

Clutch Disengagement Test

Note: It is recommended that the pilot bearing be replaced

whenever the clutch is replaced.

Note: Refer to Installation Guide TRIG1110 for a list of rec-

ommended pilot bearings.

Note: Secondary clutch failures resulting from conditions

such as pilot bearing failures, excessive torsional vibration or clutch abuse are not covered under warranty.

Fallback

No gear engagement from neutral if the truck is stationary; however, if the TECU determines the vehicle is moving, it will allow a gear engagement from neutral.

Possible Causes

This fault code can be caused by any of the following:

• Failed clutch

• Clutch thermal abuse

• Drive Disc Assembly over-speed

• Pilot Bearing failure

• Input shaft wear

• Lack of lube in Release Bearing and Bushing

Additional Tools

• Clutch jack
