DescriptionINFOID:0000000003860427
The starter motor magnetic switch is supplied with power when the ignition switch is turned to START with the
selector lever “P” or “N”.
Diagnosis ProcedureINFOID:0000000003860428
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
1.CHECK “S” CONNECTOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect “S” terminal.
3. Shift the selector lever to “P” or “N” position.
4. Check voltage between starter motor harness connector and ground.
Is the inspection result normal?
YES >> “S” terminal circuit is OK. Further inspection is necessary. Refer to STR-2, "Work Flow".
NO >> GO TO 2.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector.
2. Check continuity between starter motor “S” terminal and IPDM E/R harness connector.
Is the inspection result normal?
YES >> Inspect IPDM E/R and power supply circuit. Refer to STR-2, "Work Flow".
NO >> Repair the harness.

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".
