Eaton Fault Codes. Diagnostic Troubleshooting

Indication of codes of malfunctions

Fault codes are indicated in the system self-diagnosis mode.

Note: A computerized service tool can also be used to display fault codes.

1. Place the gear shift lever in neutral.

2. Apply the parking brake.

3. Switch on the ignition, but without starting the engine. When the engine is running, it is also possible to display codes, but you should not turn on the starter if the engine stalls.

4. Indication of active codes: Initial position - ignition is on. Turn off-turn on the ignition 2 times within 5 seconds, ending in the on position.

After 5 seconds, the diagnostic indicator light starts to indicate flashing two-digit trouble codes. In the absence of malfunctions, the diagnostic indicator lamp displays a flashing code 25 (no codes).

5. Indication of inactive codes: Initial position - ignition is on. Turn off-turn the ignition 4 times within 5 seconds, ending in the on position.

After 5 seconds, the diagnostic indicator lamp starts to indicate flashing two-digit trouble codes. In the absence of malfunctions, the diagnostic indicator lamp displays a flashing code 25 (no codes).

6. Observe the sequence of the diagnostic indicator light and record the codes. The indication is performed with a pause of 1-2 seconds between the codes, and this sequence is repeated after the completion of the indication of all codes.

Reset fault codes

Below is the procedure for discarding all inactive fault codes from the ECU memory. Reset

active fault codes are carried out automatically when the corresponding faults are eliminated.

1. Place the gear shift lever in neutral.

2. Apply the parking brake.

3. Switch on the ignition, but without starting the engine.

4. Initial position - ignition is on. Turn the ignition off and on 6 times within 5 seconds, ending in the on position.

Note: After resetting the codes, the Diagnostic Indicator Lamp will illuminate for 5 seconds.

5. Turn off the ignition and wait until the system is powered off.
