Message Overview:

Fault Message:

NO DATA - START COUNTER METER/WRG

Fault Code:

4960116APU

Associated CAS:

None

Reporting LRU: Full-Authority Digital Engine-Controller (FADEC)
System Description: 49-70-00
Schematic Diagram: 49-61-00 [ Global Express ]  [ G5000 ]  [ Global XRS ]
Wiring Diagram: 49-12-01 [ Global Express ]  [ G5000 ]  [ Global XRS ]
49-61-01 [ Global Express ]  [ G5000 ]  [ Global XRS ]

Fault Description:

The Full-Authority Digital Engine-Controller (FADEC) cannot read data from the Start Counter Meter. This shows a possible defective start counter meter or a possible short circuit or open circuit in the engine branched wiring-harness or the aircraft wiring harness.

Possible Causes:

  • Auxiliary Power Unit (APU) Full-Authority Digital Engine-Controller (FADEC) (A108)
  • Start Counter Meter (M2)
  • Associated Wiring

Troubleshooting Tips:

Advisory Wire/Service Bulletin: None

Forum Articles/Infoservice/Newsletter: None

Troubleshooting Recommendations:

  1. Examine the engine branched wiring-harness for bare wiring, kinks, worn areas and other damage (WM 49-12).

    1. If there is bare wiring, kinks, worn areas or other damage, go to step 11.
    2. If there is no bare wiring, kinks, worn areas or other damage, continue with next step.

  2. Check if the message NO DATA - START COUNTER METER/WRG still shows on the CAIMS PMAT.

    1. If NO, do close out.
    2. If YES, continue with next step.

  3. Examine the start-counter meter (M2) receptacle for contamination and damage.

    1. If there is contamination or damage, go to step 12.
    2. If there is no contamination or damage, continue with next step.

  4. Check if the message NO DATA - START COUNTER METER/WRG still shows on the CAIMS PMAT.

    1. If NO, do close out.
    2. If YES, continue with next step.

  5. Connect the hour meter/start counter reader to the start counter meter (M2). Push down and hold the push-button on the hour meter/start counter reader.

    1. If there is no data on the EVENTS LED, go to step 12.
    2. If there is data on the EVENTS LED, continue with next step.

  6. Check if the message NO DATA - START COUNTER METER/WRG still shows on the CAIMS PMAT.

    1. If NO, do close out.
    2. If YES, continue with next step.

  7. Perform wiring checks between APU (P1 (P802)) and start counter meter (M2P1).

    1. If wiring checks not good, go to step 11.
    2. If wiring checks good and if the message NO DATA - START COUNTER METER/WRG still shows on the CAIMS PMAT, continue with next step.

  8. Perform a check for insulation resistance between each pin that follows and the shell (WM 49-12) as follows:

    Pin Expected Result Result
    P1 (P802)-69 > 1 megaohm
    M2P1-C > 1 megaohm

    1. If resistance checks not good, go to step 11.
    2. If resistance checks good and if the message NO DATA - START COUNTER METER/WRG still shows on the CAIMS PMAT, continue with next step.

  9. Perform a check for insulation resistance between each pin that follows and the shell (WM 49-61). The resistance should measure more than one megaohm for each wire as follows:

    Pin Expected Result Result
    P1 (P802)-69 > 1 megohm
    A108AP1-C11 > 1 megohm

    1. If resistance checks not good, go to step 11.
    2. If resistance checks good and if the message NO DATA - START COUNTER METER/WRG still shows on the CAIMS PMAT, continue with next step.

  10. Perform wiring checks between aircraft wiring harness (J802) and FADEC (A108AP1).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  11. Replace Engine branched wiring-harness.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  12. Replace the start counter meter (M2).
  13. Do close out.
