Interpreting the Test Result indicator

The description below is presented twice since the fault counter behaves differently depending on what type of DTC that is being monitored. See the article Interpreting information in the Graph view for further information.

Unconfirmed DTC limit is +127

The description below is applicable when the Unconfirmed limit and the Failed limit are the same i.e. +127. Please refer to the article Interpreting the Fault counter for further details about the Fault counter.

The column Detailed description in the table below is applicable for the Now column in the Test Result indicator.

Confirmed

Long duration fault detected many times.

The fault counter reaches the Failed limit in many consecutive control module operation cycles (confirmed limit). See fig. no. 9.

The fault counter reaches the Passed limit and never the Failed limit in many consecutive control module operation cycles (Aged limit). See fig. no. 10.

Confirmed that the fault probably is lasting, repeating, persistent, has long duration and high frequency.

Most likely

Probably most easy

Pending

Long duration fault detected one or more times.

The fault counter reaches the Failed limit. The test runs periodically and detects faults many times consecutively in a control module operation cycle. Only the value 0, +127 and -128 of the fault counter is visible. See fig. no. 7.

The fault counter reaches the Passed limit and never the Failed limit in one control module operation cycle. See fig. no. 8.

Confirmation in progress, not yet completed.

Failed

Long duration fault detected one time.

The fault counter reaches the Failed limit. The test runs periodically and detects faults many times consecutively in a control module operation cycle. Only the value 0, +127 and -128 of the fault counter is visible. See fig. no. 5.

The fault counter reaches the Passed limit. The test runs periodically and detects no faults a number of times consecutively in a control module operation cycle. Only the value 0, +127 and -128 of the fault counter is visible. See fig. no. 6.

Probably lasting, repeating, persistent, has long duration and high frequency but that is not confirmed.

Least likely

Probably most difficult

Confirmation in progress, not yet completed.

Failed

Long duration fault detected one time.

The fault counter reaches the Failed limit. The test runs periodically and detects faults many times consecutively in a control module operation cycle. See fig. no. 8.

The fault counter reaches the Passed limit. The test runs periodically and detects no faults a number of times consecutively in a control module operation cycle. See fig. no. 9.

Probably lasting, repeating, persistent, long duration and has high frequency but that is not confirmed.

Unconfirmed

Short duration fault detected.

The fault counter reaches the Unconfirmed limit. The test runs periodically and detects faults few times consecutively in a control module operation cycle. See fig. no. 6.

The fault counter reaches the Passed limit. The test runs periodically and detects no faults a number of times consecutively in a control module operation cycle. See fig. no. 7.

Probably temporary, sporadic, transient, has short duration and low frequency.
