1. SERVICE PRECAUTIONS

• PGM-FI (PROGRAMMED FUEL INJECTION)
TROUBLESHOOTING
• First, check the MIL of the indicator.
• Be sure to turn the ignition switch OFF before discon-
necting and connecting the ECM connector.
• After inspection and repair, clear the DTC (P. 5-14) or
reset the ECM memory (P. 5-57).
• FUEL LINE SERVICE
• Do not smoke while working on the fuel system. Keep
open flame or sparks away from the work area.
• Disconnect the battery cable from the battery negative
(–) terminal.
• Before removing and installing the fuel line, relieve the
fuel pressure by loosening the service check bolt of the
high pressure side fuel strainer, as described in "How to
relieve fuel pressure" (P. 5-102).

• CHECK AFTER OPERATION
• Check the parts for secure installation and the bolts,
screws and other fasteners for secure tightening.
• Connect the battery cable to the battery negative (–) ter-
minal.
• FUEL LEAK CHECK
• Turn the ignition switch ON (but do not turn the starter)
after connecting the fuel lines. The fuel pump unit (high
pressure side) should operate for approximately 2 sec-
onds and the fuel pressure in the high pressure side fuel
line should rise. Repeat this operation 2 or 3 times and
check for fuel leakage.
• WHEN THE BOAT IS EQUIPPED WITH RADIO
EQUIPMENT
• The ECM and its wires are designed to be unaffected by
radio waves. However, the ECM can malfunction when it
senses an extremely powerful electric wave. Note the fol-
lowing to avoid malfunction of the ECM.
• Install the antenna and the body of the radio equipment
at least 50 cm (20.0 in) away from the ECM, remote con-
trol cable A and the remote control box.
• Antenna wire must not be too long. Do not route the
antenna wire along the remote control cable A and other
cables/wires.
• Do not mount the radio equipment of large output power
on the boat. (The maximum output power of the radio
equipment should be 10W when mounted on a boat.)
• Install the D-GPS antenna and the body unit at least 3 m
(10 ft) away from the engine.
• Connect the D-GPS antenna ground wire to ground.
