(only (USA), EURO 3) Test 2 Check component M33 (electric air pump). (only (USA), EURO 3) Test 3 Check component Y32 (Air pump switchover valve). (only (USA), EURO 3) 1 Test secondary air injection (function chain). (only (USA), EURO 3) Test sequence Ignition ON Test secondary air injection (function chain).(actuate with key F2.) Note: Component M4/3 (engine/ac electric suction fan) runs with an on/off ratio of 50 % during the actuations for safety reasons. Note! Communication with ECU required. 2 Check component M33 (electric air pump). (only (USA), EURO 3) Test 2-1 Test actuation of component M33 (electric air pump) Test 2-2 Test voltage supply of component M33 (electric air pump) Test 2-3 Check component K40/7kN (Air pump relay) 2-1 Test actuation of component M33 (electric air pump) Test requirement Engine at idle speed Actuate component M33 (electric air pump).(actuate with key F2.)

Communication with ECU required. 2-2 Test voltage supply of component M33 (electric air pump) Figure legend 003 Multimeter M33 (electric air pump) Test requirement Actuation is not okay. Test sequence Switch off ignition. (M33) 2 <--> 1 (M33) Switch on ignition. Actuate with key F2. Specified value Voltage[11.0...14.5] V Note! Communication with ECU required. 2-3 Check component K40/7kN (Air pump relay) Test current consumption of component K40/7kN (Air pump relay). Test requirement Fault code 'P1453' present
3 of 4 7/20/2008 8:36 AM Test sequence Switch off ignition. Connect socket box to component N3/10 (ME-SFI control module). (A.3) 3 <--> 20 (C.28) Switch on ignition. Specified value Question Amperage [0.1...0.3] A Is the measured value okay? Yes The measured value is o.k. ** End of Test ** No The measured value is not o.k. Possible cause and remedy Leads to component K40/7kN (Air pump relay) K40/7kN (Air pump relay) ** End of Test ** 3 Check component Y32 (Air pump switchover valve). (only (USA), EURO 3) Test 3-1 Test 3-2 Test actuation of component Y32 (Air pump switchover valve) Test current consumption of component Y32 (Air pump switchover valve) 3-1 Test actuation of component Y32 (Air pump switchover valve) Test sequence Ignition ON Actuate component Y32 (Air pump switchover valve).(actuate with key F2.) Note: Component M4/3 (engine/ac electric suction fan) runs with an on/off ratio of 50 % during the actuations for safety reasons. Note! Communication with ECU required. 3-2 Test current consumption of component Y32 (Air pump switchover valve) Test requirement
4 of 4 7/20/2008 8:36 AM Actuation is not okay. Test sequence Switch off ignition. Connect socket box to component N3/10 (ME-SFI control module). (A.3) 3 <--> 66 (E.10) Switch on ignition. Specified value Question Amperage [0.3...0.5] A Is the measured value okay? Yes The measured value is o.k. ** End of Test ** No The measured value is not o.k. Possible cause and remedy Voltage supply of component Y32 (Air pump switchover valve) (Wiring diagrams) Leads to component Y32 (Air pump switchover valve) Y32 (Air pump switchover valve) ** End of Test ** 2008 ALLDATA LLC.
