relay MERCEDES-BENZ SPRINTER 2006 Owner's Manual

NAG1 TRANSMISSION VERIFICATION TEST - VER 1 APPLICABILITY
1. Reconnect any disconnected components.
2. Connect the DRBIIItto the Data Link Connector.
3. With the DRBIIIt, erase ABS DTCs.
4. With the DRBIIIt, erase ECM DTCs.
5. With the DRBIIIt, erase Transmission DTCs.
6. With the DRBIIIt, display Transmission Temperature. Start and run the engine until the
Transmission Temperature is HOT, above 43É C (110É F).
7. Check the Transmission fluid and adjust if necessary. Refer to the Service Information for the
proper Fluid Fill procedure.
8. NOTE: If internal repairs were performed and the shift quality is still poor, it may
be necessary to check the internal repair. Also check for any TSBs and/or Controller
Flash updates that may apply.
9. ROAD TEST PROCEDURE
10. Road test the vehicle. Make fifteen to twenty 1-2, 2-3, 3-4 and 4-5 upshifts.
11. Perform these shifts from a standing start to 72 km/h (45 MPH) with a constant throttle
opening of 20 to 25 degrees.
12. With speeds below 40 km/h (25 MPH), make five to eight wide open throttle kickdowns to
1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.
13. With the DRBIIIt, read Transmission DTCs.
Were there any Diagnostic Trouble Codes set?All
Ye s!Repair is not complete, refer to appropriate symptom.
No!Repair is complete.
ROAD TEST VERIFICATION - VER-2 APPLICABILITY
1. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
2. If this verification procedure is being performed after a non-DTC test, perform steps 3 and
4.
3. Check to see if the initial symptom still exists. If there are no trouble codes and the symptom
no longer exists, the repair was successful and testing is now complete.
4. If the initial or another symptom exists, the repair is not complete. Check all pertinent
Technical Service Bulletins (TSBs) and return to the Symptom List if necessary.
5. For previously read DTCs that have not been dealt with, return to the Symptom List and
follow the diagnostic path for that DTC; otherwise, continue.
6. If the Engine Control Module (ECM) has not been changed, perform steps 7 and 8, otherwise,
continue with step 9.
7. With the DRB IIIt, erase all diagnostic trouble codes (DTCs), then disconnect the DRB IIIt.
8. Turn the ignition off for at least 10 seconds.
9. If equipped with a Transfer Case Position Switch, perform step 10, otherwise, continue with
step 11.
10. With the ignition switch on, place the Transfer Case Shift Lever in each gear position,
stopping for 15 seconds in each position.
11. Ensure no DTCs remain by performing steps 12 through 15.
12. Road test the vehicle. For some of the road test, go at least 64 km/h (40 MPH). If this test
is for an A/C Relay Control Circuit, drive the vehicle for at least 5 minutes with the A/C on.
13. At some point, stop the vehicle and turn the engine off for at least 10 seconds, then restart
the engine and continue.
14. Upon completion of the road test, turn the engine off and check for DTCs with the DRB IIIt.
15. If the repaired DTC has set again, the repair is not complete. Check for any pertinent
Technical Service Bulletins (TSBs) and return to the Symptom List. If there are no DTCs, the
repair was successful and is now complete.
Are any DTCs or symptoms remaining?All
Ye s!Repair is not complete, refer to appropriate symptom.
No!Repair is complete.
