Technical Service Bulletin
Technical Background
The motronic engine control module power supply relay, J271, is not functioning properly. Because the J271 relay
controls battery voltage (Terminal 30) via a ground signal sent from the ECM, numerous faults can occur in
multiple control modules when it is not functioning properly.
Production Solution
Change of relay construction at Tyco Electronics. Installation of Hella relay in production.
Service
1.
Confirm that DTC P068A00 is stored in the ECM, J623 (address word 01):
• If DTC P068A00 is stored in the ECM, proceed with this bulletin.
• If DTC P068A00 is not stored in the ECM, do not proceed with this bulletin. Continue with diagnosis.
Tip: The images used in this bulletin are of a 2014 A4 vehicle. Use Elsa to confirm component and
connector terminal locations for the specific vehicle being repaired.
2.
Check Elsa for the location of the J271 relay (Wiring diagrams
>> Component locations >> Component Locations: Relays)
(Figure 1).

Check the relay manufacture build
information on the relay. This information is
printed under “645” on the relay:
• If the relay is from Tyco Electronics and
has a yellow label (Figure 7, 1), replace
the relay and proceed to step 10.
• If the relay is from Tyco Electronics and
has a white label (Figure 7, 2) or from
Hella and has a white label (Figure 7, 3),
do not replace the relay. Proceed to step
9.

Figure 7. Relay manufacture data: Tyco Electronics relay with
a yellow label (1), Tyco Electronics relay with a white label (2),
Hella relay with a white label (3).
Check the J271 relay according to the instructions in Elsa at: Engine >> Generic Scan Tool >> ST Generic
Scan Tool >> Diagnosis and Testing >> Diagnostic Procedures >> Engine Component Power Supply Relay,
Checking.
10. Check for battery voltage on J271
relay terminals 1 and 3 (Figure 8).
If no voltage is found, do not
proceed with this bulletin.
Continue with diagnosis.

Technical Service Bulletin
11. With the ECM disconnected, check the wiring from J271 relay terminal 2 to the ECM:
• If voltage and wiring are good, replace the J271 relay.
• If voltage and wiring are not good, do not proceed with this bulletin. Continue with diagnosis.
Note: Only use a DVOM when taking measurements. If a non-approved device is used to check terminal
2, it can damage the ECM.
12. After replacing the J271 relay, reinstall the ECM and confirm that the vehicle can be started. If vehicle cannot
be started, continue with diagnosis.
13. Reinstall all components.
14. Check vehicle battery. Charge battery as needed before returning to customer.
15. Clear fault memory via ODIS GFF. Send diagnostic log via GFF Paperless.
