How to Read Flowcharts
A flowchart is designed to be used from start to final repair. lt's like a map showing you the shortest distance. But beware:
lf you go off the "map" anywhere but a "stop" symbol, you can easily get lost.
brARn
t.-OotO tw"t Describes the conditions or situation to start a troubleshooting flowchart.
FcTloNl Asks you to do something; perform a test, set up a condition etc.
@ Asks you about the result of an action, then sends you in the appropriate troubleshooting direction.
fS-OPl The end of a series of actions and decisions, describes a final repair action and sometimes directs you to
(bold type) an earlier part of the flowchart to confirm your repair.
NOTE:
. The term "lntermittent Failure" is used in these charts. lt simply means a system may have had a failure, but it checks
out OK at this time. lf the Malfunction Indicator Lamp (MlL) on the dash does not come on, check for poor connections
or loose wires at all connectors related to the circuit that you are troubleshooting (see illustration below).
. Most of the troubleshooting flowcharts have you reset the Engine Control Module (EcM)/Powertrain Control Module(PCM) and try to duplicate the Diagnostic Trouble Code (DTC). lf the problem is intermittent and you can't duplicate the
code, do not continue though the flowchart. To do so will only result in confusion and, possibly, a needlessly replaced
ECM/PCM,
o "Open" and "Short" are common electrical terms. An open is a break in a wire or at a connection. A short is an acci-
dental connection of a wire to ground or to another wire. ln simple electronics, this usually means something won't
work at all. In complex electronics (like ECM'S/PCM'S), this can sometimes mean something works, but not the way it's
suooosed to.

Fuel Cut-off Control
. During deceleration with the throttle valve closed, current to the fuel injectors iscutoffto improvefuel economyat
speeds over 970 rpm ('97 - 98 models), 920 rpm ('99 - 00 modelsl.
. Fuel cut-off action also takes place when engine speed exceeds 6,500 rpm ('97 - 98 models), 6900 rpm ('99 - 00
models), regardless of the position of the throttle valve, to protect the engine from over-rewing.
With Ay'T model. the PCM cuts the fuel at engine speeds over 5,000 rpm when the vehicle is not moving.*'
4,./C Comoressor Clutch Relav
When the ECM/PCM receives a demand for cooling from the air conditioning system, it delays the compressor from
being energized, and enriches the mixture to assure a smooth transition to the Ay'C mode.
Evaporative Emission (EVAP) Purge Control Solenoid Valve
When the engine coolant temperature is above 154"F (68'C), the ECM/PCM controls the EVAP purge control solenoid
valve which controls vacuum to the EVAP purge control canister,
Alternator Control
The system controls the voltage generated at the alternator in accordance with the electrical load and driving mode.
which reduces the engine load to improve the fuel economy.
PCM Fail-saf e/Back-up Functions
1. Fail-safe Function
When an abnormality occurs in a signal from a sensor, the ECM/PCM ignores that signal and assumes a pre-pre
grammed value for that sensor that allows the engine to continue to run.
2. Back-up Function
When an abnormality occurs in the ECM/PCM itself, the fuel injectors are controlled by a back-up circuit independent
of the system in order to permit minimal driving.
3. Self-diagnosis Function IMalfunction Indicator Lamp (MlL)l
When an abnormality occurs in a signal from a sensor, the ECM/PCM supplies ground for the MIL and stores the DTC
in erasable memory. When the ignition is initially turned on {ll), the ECM/PCM supplies ground for the MIL for two
seconds to check the MIL bulb condition.
4. Two Trio Detection Method
To prevent false indications, the Two Trip Detection Method is used for the HO2S*1, fuel metering-related. idle control
system, ECT sensor and EVAP control system self-diagnostic functions. When an abnormality occurs, the ECM/PCM
stores it in its memory. When the same abnormality recurs after the ignition switch is turned OFF and ON (ll) again,
the ECM/PCM informs the driver by lighting the MlL. However, to ease troubleshooting, this function is cancelled
when you jump the service check connector, The MIL will then blink immediately when an abnormality occurs.
5. Two (or Three) Driving Cycle Detection Method {'97 model)
A "Driving Cycle" consists of starting the engine, beginning closed loop operation, and stopping the engine. lf misfir-
ing that increases emissions or EVAP control system malfunction is detected during two consecutive driving cycles.
or TWC deterioration is detected during three consecutive driving cycles, the ECM/PCM turns the MIL on. However, to
ease troubleshooting, this function is cancelled when you jump the service check connector. The MIL will then blink
immediately when an abnormality occurs.

Transler Mochanism {4WD}
The transfer mechanism consists of the transfer shaft drive gear. the transfer shaft. the transfer drive gear, the transfer driv-en gear shaft, and the companion flange, The transfer mechanism assembly is on the rear side ot the transmission. besidethe differential. The transfer shaft drive gear on the final driven gear drives the transfer shaft driven qear. power is transmit-ted to the rear differential via the transfer shaft and the Drooeller shaft.
Clutches
The four-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears.When the hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs andsteel plates together, locking them so they don't slip. Power is then transmifted through the engaged clutch pack to its hu$mounted gear. When hydraulic pressure is bled from the clutch pack, the piston releases the friction discs and steel plates, andthey are free to slide past each other. This allows the gearto spin independently on its shaft, transmitting no power.
lst Clutch
The 1st clutch engages/disengages lst gear, and is located at the end ofthe mainshaft, just behind the end cover.The 1st clutch is supplied hydraulic pressure by its ATF feed pipe within the mainshaft.

The 1st-hold clutch engages/disengages 1st-hold or E position, and is located at the middle of the sub-shaft. The 1st-holdclutch is supplied hydraulic pressure by its ATF feed pipe within the sub-shaft.

Inspection and Adjustment
Pump Belt
When using a new belt. first adjust the deflection or ten-
sion to the values for the new belt, then readjust the
deflection or tension to the values for the used belt after
running engine for five minutes.
Inspection
Note these items during inspection:
a lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions lor the tension
gauge.
'1. Remove the P/S reservoir from the bracket, and set
it aside.
2. Attach the belt tension gauge to the belt with the
gauge face toward the engine, and measure the ten-
sion of the belt.
Remove the belt tension gauge carefully to avoid
hitting the gauge reset lever.
Tension:
Used Belt: 390 - 540 N {40 - 55 kgf, 88 - 121 lbf)
