For a detail ed descripti on of the el ect ronic engi ne cont rols , refer to the relevant Des cri pti on and Operati on s ect ion i n t heworks hop manual .REFER to: Elect ronic Engine Cont rols (303-14 El ect ronic Engine Cont rols - TD4 2.2L Di esel , Des cri pti on and Operati on).
Inspection and Verification
CAUTION: Di agnos is by s ubs ti tut ion from a donor vehicle is NO T acceptabl e. Subs ti tut ion of cont rol modules doesnot guarant ee confirmat ion of a faul t, and may als o caus e addit ional fault s i n t he vehi cl e being t est ed and/or t he donorvehi cl e.
1. Verify t he cus t omer concern.1.
2. Vis ually ins pect for obvious s igns of mechani cal or electrical damage and sys tem integrit y.2.
