Complaint:
The engine diagnosis warning lamp - check engine lamp (CEL) is active.
One or more of the faults relating to the throttle valve actuator (M16/6) listed under 'Control unit / Fault' is/are stored in
the engine control unit (N3/10).
Cause:
Contamination of the contact surfaces could cause the fault to occur.
Remedy:
If all the test steps stored in Xentry Diagnostics have been performed and no component faults were found, the following work must be carried out:
M276:
-Visually inspect contacts at throttle valve actuator (M16/6)
-Visually inspect contacts at engine control unit (N3/10) connector M+F
M278:
-Visually inspect contacts X26 (intermediate connector M16/6 - N3/10) (see WIS reference for location)
-Visually inspect contacts at engine control unit (N3/10) connector M+F
If no noticeable problems are found, reconnect the connector and erase the fault.
Do not replace any components!
If the fault reoccurs after above checks are performed or visual inspections reveal concerns, please address the problem through PTSS by opening the case and providing all possible information including any related illustrations.
