(c)Check the indicator.
(1)Turn the ignition switch to the ON position.
(2)Check that the CRUISE MAIN indicator light comeson when the main switch is ON, and that the indica-
tor light goes off when the main switch is OFF.
HINT:
If there is a problem with the indicator, inspect the cruise main
indicator light circuit (See page 05±1722).
(d)Check the DTC.
HINT:
If a malfunction occurs in the vehicle speed sensors or stop
lamp switch assy, etc. during cruise control driving, the ECU ac-
tuates AUTO CANCEL of the cruise control and then the
CRUISE MAIN indicator light will start to blink, informing the
driver of a malfunction. At the same time, data of the malfunc-
tion is stored as a diagnostic trouble code, or DTC.
(e)Output of the DTC using diagnosis check wire. (1)Using SST, connect terminals TC and CG
of DLC3.
SST09843±18040
(2)Turn the ignition switch to the ON position.
(3)Read the DTC on the CRUISE MAIN indicator light.
HINT:
If the DTC is not output, inspect the cruise main indicator light
circuit (See page 05±1722) and diagnosis circuit (See page
05±1729).
For example, the normal blinking pattern and the blinking pat-
tern for code 52 are shown in the illustration.

(h) Wipe up any gasoline.
(i) Reconnect the negative (±) battery cable.
(j) Connect the hand±hand tester to the DLC3.
(k) Measure the fuel pressure.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses connections, the fuel
pump, the fuel filter and the fuel pressure regulator.
(l) Disconnect the hand±held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
(o) Stop the engine.
(p) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, the pres-
sure regulator and/or the injectors.
(q) After checking the fuel pressure, disconnect the negative
(±) battery cable and carefully remove SST and the fuel
tube connector to prevent gasoline from splashing.
(r) Reconnect the No. 1 fuel pipe (fuel tube connector).
CAUTION:
After taking the precautions, connect the fuel tube con-
necter (quick type).
2. CHECK FUEL PUMP OPERATION AND FUEL LEAK
(a) When using the hand±held tester
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON and the hand±held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(3) Select the active test mode on the hand±held tester.
(4) Perform the active test. Check that the fuel pump
operates and check for fuel leaks.
