7C TROUBLESHOOTING
TROUBLESHOOTING
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.

Replacement of Fuse
1. When replacing a fuse, be sure to replace it with
one of the specified capacity.
If, after a fuse has been replaced, it fails again, there
is probably a short in the circuit, and the wiring
should be checked.
2. Be sure the negative battery terminal is disconnect-
ed before replacing a main fuse.
3. When replacing a fuse, use the supplied fuse puller
in the fuse box cover.
Thin Insulation Wire
To reduce the weight of the wiring harness, a thin
coating of high resistance insulation material is used.
Shielded braid wire
This wire is used to prevent a malfunction in impor-
tant circuits that are susceptible to outside signals or
interference.
