Test sequence

Ignition ONTest 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 speedActuate component M33 (electric air pump).(Actuate with key F2.)
