REMARKS:
Major service interval at 12 months/20,000 km (12,000 Miles), Lubrication service based on distance only 10,000 km (6,000 Miles) not time
After 80,000 km (48,000 Miles) or 48 months, continue to follow the described maintenance items and intervals periodically.
As for * marked items in this maintenance chart, please pay attention to the following points.
*1 Replacement of the timing belt is required at every 100,000 km (60,000 Miles). Failure to repace the timing belt may result in damage to the engine.
*2 If the vehicle is operatie under the following conditions, it is suggested that the engine oil and oil filter be changed more often than at usual recommended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c) Driving for a prolonged period in cold temperatures or driving only short distances regulary.
*3. If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more often than at usual recommended intervals.
*4. This is a full function check of all electrical systems, i.e., all lights, washers (including condition of blades) electrical windows, sunroof, horn, etc....
*5. Replace every two years.
If there has been continuous hard driving, mountain driving, or if the brakes are used extensively or the vehicle is operated in extremely humid climates, the
brake fluid should be changed annually.

TROUBLESHOOTING (G4A-HL) 7B
TROUBLESHOOTING (G4A-HL)
GENERAL NOTE
In the event of a problem with the automatic transaxle, the cause may be in the engine, power train,
hydraulic control system, or electrical control system.
When troubleshooting, therefore, it is recommended to begin from those points that can be judged
quickly and easily. The recommended troubleshooting sequence is described below.
STEP 4: TIME LAG TEST
Check time lag of oil pressure supply
STEP 6: OIL PRESSURE TEST Check line, throttle, and governor pressures
This step checks conditions surrounding the automatic
transaxle.
This step checks the electrical control system.
• Function of the electrical control system
• Components
This step checks the power train. • Friction element slipping • Torque converter capacity
This step checks operation of the hydraulic control system. • Accumulators • Friction elements slipping • Regulating valves
This step checks functions of the electric control system and
hydraulic control system.
This step checks major points of the hydraulic control system.
• Oil pump • Line pressure control • Throttle pressure control
• Governer pressure control
STEP 5: ROAD TEST Check items on road test
• Shift point • Shift schedule
• Kick-down • Shift shock • Lock-up and overdrive inhibition
By following the above 6 steps, the cause of the problem should be located.
As another guide to faster location of the causes of problems, the Quick Diagnosis Chart is included
at pages 7B—42, 43.
In this chart, a circle is used to indicate the components that might be the cause of trouble for 20
types of problems. It is only necessary to check those components indicated by circles, at each step
of the troubleshooting process, in order to quickly locate the cause of the problem.

GENERAL NOTE
In the event of a problem with the automatic transaxle, the cause may be in the engine, powertrain,
hydraulic control system, or electrical control system. When troubleshooting, it is recommended to
begin from those points that can be judged quickly and easily. The recommended troubleshooting
sequence is described below.
STEP 1: PRELIMINARY INSPECTION Check preliminary items • ATF level and condition
• Oil leakage • Selector lever position
• Vacuum leakage
• Idle speed and ignition timing
• Tire inflation pressure • Inhibitor switch
This step checks conditions surrounding the automatic
transaxle.
STEP 2: STALL TEST Check engine stall speed This step checks the powertrain.
• Friction element slipping
• Torque converter capacity
STEP 3: TIME LAG TEST Check time lag of oil pressure supply This step checks operation of the hydraulic control system. • Friction elements slipping
• Regulating valves
STEP 4: ROAD TEST Check items on road test
• Shift point • Shift schedule
• Kick-down • Shift shock
This step checks functions of the electrical control system
and hydraulic control system.
STEP 5: OIL PRESSURE TEST Check line pressures and governor pressure This step checks major points of the hydraulic control system.
• Oil pump • Line pressure control • Governer pressure control
By following the above five steps, the cause of the problem should be located.
As another guide to faster location of the causes of problems, the Quick Diagnosis Chart is included
at pages 7C—9 to 7C—11.
In this chart, a circle is used to indicate the components that might be the cause of trouble for 54
types of problems. It is only necessary to check those components indicated by circles, at each step
of the troubleshooting process, in order to quickly locate the cause of the problem.
