S CONNECTOR CIRCUIT
DescriptionINFOID:0000000001728580
Terminal "1" (S) is the power supply for the starter motor magnetic switch. Terminal 1 is supplied with power
when the ignition switch is turned to the START position while the selector lever is in the P or N position.
Diagnosis ProcedureINFOID:0000000001728581
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 STARTER MOTOR MAGNETIC SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect starter motor connector F28.
3. Shift transmission into park or neutral.
4. Check voltage between starter motor harness connector F28
terminal 1 and ground with the ignition in START.
Is battery voltage present?
YES >> Magnetic switch circuit is OK. Further inspection necessary. Refer to STR-25, "Work Flow".
NO >> GO TO 2
2.CHECK CONNECTOR
1. Turn ignition switch OFF.
2. Check the IPDM E/R harness connector E44 and starter motor harness connector F28 for damage, bent
pins and loose connections.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair the terminal and connector.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector E44 and starter motor connec-
tor F28.
2. Check continuity between starter motor harness connector F28
(A) terminal 1 and IPDM E/R harness connector E44 (B) termi-
nal 19.
3. Check continuity between starter motor harness connector F28
(A) terminal 1 and ground.
Are the continuity test results as specified?
YES >> Further inspection necessary. Refer to STR-25, "Work Flow".
NO >> Repair the harness.

*1: Operates when OD OFF. (OD OFF indicator lamp is on.)
*2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not contract
because oil pressure area on the “release” side is greater than that on the “apply” side.
*3: Oil pressure is applied to 4th “apply” side on condition *2 above, and brake band contracts.
*4: A/T will not shift to 4th when OD OFF. (OD OFF indicator lamp is on.)
: Operates.
A: Operates when throttle opening is less than specification**, activating engine brake.
B: Operates during “progressive” acceleration.
C: Operates but does not affect power transmission.
D: Operates when throttle opening is less than specification**, but does not affect engine brake.
- **: Overrun clutch remains in engaged condition when throttle opening is less than 1/16.
