2 Section 1: Diagnostic Introduction
CAUTIONS
To reduce the chance of personal injury and/or property damage, the following instructions must
be carefully observed.
Proper service and repair are important to the safety of the service technician and the safe, reli-
able operation of all Electronic Fuel Injection (EFI) equipped engines. If part replacement is nec-
essary, the part must be replaced with one of the same part number or with an equivalent part.
Do not use a replacement part of lesser quality.
The service procedures recommended and described in this service manual are effective meth-
ods of performing service and repair. Some of these procedures require the use of tools specifi -
cally designed for the purpose.
Accordingly, anyone who intends to use a replacement part, service procedure, or tool which is
not recommended by the manufacturer, must fi rst determine that neither his safety nor the safe
operation of the unit will be jeopardized by the replacement part, service procedure or tool se-
lected.
It is important to note that this manual contains various Cautions and Notices that must be care-
fully observed in order to reduce the risk of personal injury during service or repair, or the possi-
bility that improper service or repair may damage the unit or render it unsafe. It is also important
to understand that these "Cautions" and "Notices" are not exhaustive, because it is impossible
to warn of all the possible hazardous consequences that might result from failure to follow these
instructions.
All information, illustrations and specifi cations contained in this manual are based on the latest
product information available at the time of publication approval. The right is reserved to make
changes at any time without notice.
