Fault Code Retrieval/Clearing

Retrieving Fault Codes

Retrieve fault codes by enabling self-diagnostic mode.

Note: Use a PC-based Service Tool, such as the ServiceRanger to retrieve fault codes.

1. Place the Shift Lever in neutral.

2. Set the parking brake.

3. Turn the key on but do not start the engine. If the engine is running, you may still retrieve codes; however, do not engage the Starter if the engine stalls.

4. To Retrieve Active Codes: Turn the key off and on 2 times within 5 seconds ending with the key on. After 5 seconds, the Service light begins flashing 2-digit fault codes. If no faults are Active, the Service light will flash Code 25 (no codes).

6. Observe the sequence of flashes on the Indicator light and record the codes. A 1 to 2 second pause separates each stored code, and the sequence automatically repeats after all codes have been flashed.

5. To Retrieve Inactive Codes: Start with the key on. Turn key off and on 4 times within 5 seconds ending with the key on. After 5 seconds, the Service light begins flashing 2-digit fault codes. If no faults are Active, the Service light will flash Code 25 (no codes).

TRTS0062 Electrical Pretest Procedure | Electrical System Pretest

Electrical System Pretest

Overview

The test does not relate to any specific fault code, but must be completed before performing “Fault Code Isolation Table” procedures. The Electrical Pretest verifies the batteries are fully charged.

Detection

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

Fallback

There is no fallback for the Electrical Pretest; however, it may effect other systems.

Possible Causes

This pretest can be used for any of the following:

• Low batt

Starter-battery connections

•

eries

Additional Tools

• Basic hand tools

• Eaton Test Adapter kit

• Digital volt/ohm meter

• Battery load tester

Fault Code 26: Clutch Slip | Fault Isolation Procedure TRTS0062

Fault Code 26: Clutch Slip

J1587:MID 130 SID 55 FMI 10

Overview

Fault Code 26 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 1 second, the Fault Code is set.

Conditions to Set Fault Code Active

Fallback

This fault causes a down-shift fallback. Once the vehicle is stopped, starting gear and reverse gear can be engaged. The fault will clear at power down and up shifts will be allowed until the fault is detected again.

Possible Causes

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

• Worn or broken clutch

Additional Tools

• Basic hand tools

• Eaton Test Adapter kit

• Clutch jack

J1587:MID 130 SID 55 FMI 7

Overview

Fault Code 27 indicates the clutch has not disengaged as expected.

Detection

Starting at key on and throughout operation, the Shift Controller constantly measures engine RPM and idle torque from the engine.

When engaging a start gear, if the engine speed falls significantly below idle or engine torque rises significantly above idle torque the fault is set.

If in gear and the vehicle is brought to a stop and engine speed falls significantly below idle, the fault is set.

Conditions to Set Fault Code Active

Fallback

There is no fallback associated with this failure; however, it may be difficult to achieve gear engagement or disengagement.

Possible Causes

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

• Worn or broken clutch

J1587:MID 130 SID 52 FMI 3, 4, 5, 7

Overview

Fault Code 28 indicates either an electrical or mechanical failure in the wet clutch system.

Detection

Starting at key on and throughout operation, the Transmission Controller constantly monitors this circuit. A failure of short to battery, short to ground or open circuit sets the fault code Active.

When the wet clutch is locked after urge to move, engine speed and Input Shaft speeds are compared. If the engine speed is significantly higher than the Input Shaft speed for a period of 5 seconds, the wet clutch is slipping.

Conditions to Set Fault Code Active

Fallback

There is no fallback mode; however, if the failure mode is open circuit, the engine will be disengaged from the Input Shaft.

Possible Causes

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

• Transmission Controller

• Transmission Harness

• Low fluid level

• Wet clutch system

Additional Tools

• Basic hand tools

• Digital volt/ohm meter

• Eaton Test Adapter kit

Fault Code 41: Range Failed to Engage | Fault Isolation Procedure TRTS0062

Fault Code 41: Range Failed to Engage

J1587:MID 130 SID 56 FMI 7

Overview

Fault Code 41 indicates the transmission is unable to complete a shift across the range. The range is either stuck in HI or LO, or cannot complete engagement into HI or LO.

Detection

The transmission attempts the same range shift 5 consecutive times and determines the shift cannot be completed based on the speeds across the back box.

Conditions to Set Fault Code Active

Fallback

This fault causes a 5-speed fallback and the transmission stays in either LO range or HI range. When the vehicle comes to a stop, an attempt to shift into LO range is made.

Possible Causes

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

• Low air pressure

• Contaminated air supply

• Air leak

• Range valve

• Range Synchronizer

• Range Actuator, Cylinder, Piston or Yoke

Additional Tools

• Basic hand tools

• Two 0-100 PSI Air Pressure gauges
