Danger

Risk of death. Death may occur if body parts are drawn into rotating vehicle parts.

Do not insert your hand into rotating parts. Wear closed and snug-fitting work clothes. Secure area of rotating vehicle components against unauthorized access.

AS00.00-Z-0004-01A

Danger

Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC)

Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines.

AS00.00-Z-0035-01A

Danger

Risk of explosion caused by fuel igniting, risk of poisoning caused by inhaling and swallowing fuel as well as risk of injury to eyes and skin caused by contactwith fuel.

No fires, sparks, open flames or smoking. Pour fuels into suitable and appropriately marked containers only.
Wear protective clothing when handling fuel.

Engine control monolith (ECM) fuel injection and ignition system position of components

Engine 166
If, in vehicles with an air-conditioning system while the ignition is ON, coupling 1 of the ECU (N3/5) is removed, the fan starts up on full speed (limp-home mode). When placing the connector housing in position, ensure that they are not tilted. Otherwise, pins on the control unit may be bent. Reading out the fault code with the pulse counter is not possible.
