SFI SYSTEM - Starter Signal Circuit
DESCRIPTION
While the engine is being cranked, current flows from terminal STAR of the main body ECU to the park/neutral position switch and also flows to terminal STA of the ECM (STA signal).
WIRING DIAGRAM
Refer to DTC P0617 ().
INSPECTION PROCEDURE
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
- This chart is based on the premise that the engine can crank normally. If the engine cannot crank normally, proceed to Problem Symptoms Table ().
| 1.READ VALUE USING GTS (STARTER SIGNAL) |
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.
Read the value.
- OK:
| Engine Switch Position | Starter Signal |
| On (IG) | OFF |
| START | ON |
| OK | |
| |
| PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE ()
|
|
| 2.CHECK STARTER RELAY (ST) (POWER SOURCE) |
Remove the starter relay (ST) from the engine room relay block.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Condition | Specified Condition |
| Starter relay (ST) terminal 2 - Body ground | Engine cranking | 11 to 14 V |
| Starter relay (ST) terminal 1* - Body ground | Engine cranking | 11 to 14 V |
*: URJ202L-GNTEKC
- The engine does not crank because the relay is not installed.
Reinstall the starter relay (ST).
| 3.INSPECT STARTER RELAY (ST) |
Inspect the starter relay (ST) ().
| | REPLACE STARTER RELAY (ST) |
|
|
| 4.CHECK HARNESS AND CONNECTOR (STARTER RELAY (ST) - BODY GROUND) |
Remove the starter relay (ST) from the engine room relay block.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| Starter relay (ST) terminal 1 - Body ground | Always | Below 1 Ω |
| Starter relay (ST) terminal 2* - Body ground | Always | Below 1 Ω |
*: URJ202L-GNTEKC
Reinstall the starter relay (ST).
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (STARTER RELAY (ST) - BODY GROUND) |
|
|
| OK | |
| |
| REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - PARK/NEUTRAL POSITION SWITCH) |
|
| 5.CHECK HARNESS AND CONNECTOR (STARTER RELAY (ST) - PARK/NEUTRAL POSITION SWITCH) |
Remove the starter relay (ST) from the engine room relay block.
Disconnect the park/neutral position switch connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| Starter relay (ST) terminal 1* - C24-5 (L) | Always | Below 1 Ω |
| Starter relay (ST) terminal 2 - C24-5 (L) | Always | Below 1 Ω |
| Starter relay (ST) terminal 1* or C24-5 (L) - Body ground | Always | 10 kΩ or higher |
| Starter relay (ST) terminal 2 or C24-5 (L) - Body ground | Always | 10 kΩ or higher |
*: URJ202L-GNTEKC
Reinstall the starter relay (ST).
Reconnect the park/neutral position switch connector.
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 6.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY |
Inspect the park/neutral position switch assembly ().
| | REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY ()
|
|
|
| 7.CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - MAIN BODY ECU) |
Disconnect the park/neutral position switch connector.
Disconnect the main body ECU connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| C24-4 (B) - E1-8 (STR) | Always | Below 1 Ω |
| C24-4 (B) or E1-8 (STR) - Body ground | Always | 10 kΩ or higher |
Reconnect the park/neutral position switch connector.
Reconnect the main body ECU connector.
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| GO TO ENTRY AND START SYSTEM ()
