14. Disconnect the quick-connect fitting (A): Hold the
connector (B) with one hand, and squeeze the
retainer tabs (C) with the other hand to release
them from the locking tabs (D). Pull the connector
off.
NOTE: Be careful not to damage the line (E) or other parts.
 Do not use tools.
 If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push
the connector until it comes off easily.
 Do not remove the retainer from the line; once removed, the retainer must be replaced with a
new one.
15. After disconnecting the quick-connect fitting, check it for dirt or damage (see step 4 on page 11-330).
16. Do the battery terminal reconnection procedure (see page 22-68). 1. Remove the under-dash fuse/relay box (see page
22-66), then remove PGM-Fl main relay 2 (FUEL
PUMP) (A) from the under-dash fuse/relay box.
2. Reinstall the under-dash fuse/relay box.
3. Start the engine, and let it idle until it stalls. NOTE: If any DTCs are stored, clear and ignore
them.
4. Turn the ignition switch to LOCK (0).
5. Remove the fuel fill cap.
6. Do the battery terminal disconnection procedure (see page 22-68).

4. Align the quick-connect fittings with the line (A),
and align the retainer locking tabs (B) with the
connector grooves (C). Then press the quick-
connect fittings onto the line until both retainer tabs
lock with a clicking sound.
NOTE: If it is hard to connect, put a small amount of
new engine oil on the line end.

5. When you reconnect the connector with the old
retainer, make sure the connection is secure and
the tabs (A) are firmly locked into place; check
visually and also by pulling the connector (B).
When you replace the fuel line with a new one,
make sure you remove the ring pull (C) upwards
after you confirm the connection is secure.
NOTE: Before you remove the ring pull, make sure
the fuel line connection is secure. If the connection
is not secure, the ring pull could break when you try
to remove it. 6. Reconnect the negative cable to the battery, and
turn the ignition switch to ON (II) (but do not
operate the starter motor). The fuel pump will run
for about 2 seconds, and fuel pressure will rise.
Repeat this two or three times, then check that
there is no leakage in the fuel supply system.

The electronic control system consists of the powertrain control module (PCM), sensors, and solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions.
The PCM receives input signals from sensors, switches, and other control units, processes data, and outputs signals
for the engine control system and the A/T control system. The A/T control system includes shift control, grade logic
control, clutch pressure control, and lock-up control.
The PCM switches the shift solenoid valves and the A/T clutch pressure control solenoid valves ON and OFF to control
gear selection and torque converter clutch lock-up.

The PCM actuates A/T clutch pressure control solenoid valves A, B, and C to control the clutch pressure. When shifting
between lower and higher gears, the clutch pressure regulated by A/T clutch pressure control solenoid valves A, B,
and C engages and disengages the clutch smoothly.
The PCM receives input signals from the various sensors and the switches, processes data, and outputs current to A/T
clutch pressure control solenoid valves A, B, and C.
