Magnet is secured to yoke by bonding agent. Check magnet to see
that it is secured to yoke and for any cracks. Replace malfunctioning
parts as an assembly.
CAUTION:
Never clamp yoke in a vise or strike it with a hammer.
ARMATURE CHECK
1. Continuity test (between two segments side by side)
- Replace if continuity does not exist.
2. Insulation test (between each commutator bar and shaft)
- Replace if continuity exists.
3. Check commutator surface.
- Grind commutator with No. 500 – 600 emery paper if the surface
is rough.
4. Check diameter of commutator.
- Replace armature assembly if the measurement value is less
than the specified value.

Work FlowINFOID:0000000003848914
INTRODUCTION
The TCM receives signals from the vehicle speed sensor and PNP switch. Then it provides shift control or
lock-up control via CVT solenoid valves.
The TCM also communicates with the ECM by means of signals
sent from sensing elements used with the OBD-related parts of the
CVT system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose a malfunction that occurs inter-
mittently rather than continuously. Most intermittent malfunctions are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only may not find the cause of the malfunctions. A
road test with CONSULT-III (or GST) or a circuit tester connected
should be performed. Follow the “DETAILED FLOW”.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such malfunctions, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A “Diagnostic Work Sheet” as
shown on the example (Refer to TM-10
) should be used.
Start your diagnosis by looking for “conventional” malfunctions first.
This will help troubleshoot driveability malfunctions on an electroni-
cally controlled engine vehicle.
Also check related Service Bulletins.
DETAILED FLOW
1.COLLECT THE INFORMATION FROM THE CUSTOMER
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using the diagnosis work sheet. Refer to TM-10, "
Diagnostic Work Sheet".
>> GO TO 2.
2.CHECK SYMPTOM 1
Check the following items based on the information obtained from the customer.
 Fail-safe. Refer to TM-120, "
Fail-safe".
 CVT fluid inspection. Refer to TM-142, "
Inspection".
 Line pressure test. Refer to TM-146, "
Inspection and Judgment".
