CHECK HARNESS AND CONNECTOR (STARTER RELAY [ST] - ECM)
ECD SYSTEM (for i-ART) - Starter Signal Circuit |
DESCRIPTION
While the engine is being cranked, current flows from terminal ST2 of the ignition switch to the park/neutral position switch and also flows to terminal STA of the ECM (STA Signal).WIRING DIAGRAM
Refer to DTC P0617 (HILUX_TGN26 RM000000TA011PX_05.html).INSPECTION PROCEDURE
- NOTICE:
- Inspect the fuses of circuits related to this system before performing the following inspection procedure.
- After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK05AX.html) and initialization (HILUX_TGN26 RM000000TIN058X.html).
- HINT:
- This chart is based on the premise that the engine can crank normally. If the engine cannot crank normally, proceed to Problem Symptoms Table (HILUX_TGN26 RM0000012WF050X.html).
| 1.READ VALUE USING GTS (STARTER SIGNAL) |
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Data List / Starter Signal.
Read the value.
- OK:
Ignition Switch Condition Starter Signal ON OFF START ON

| 2.CHECK HARNESS AND CONNECTOR (STARTER RELAY [ST] - ECM) |
Remove the starter relay (ST) from the engine room relay block and junction block assembly.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition ST relay terminal 1 - G157-6 (STA) Always Below 1 Ω ST relay terminal 1 or G157-6 (STA) - Body ground Always 10 kΩ or higher
Reinstall the starter relay (ST).
Reconnect the ECM connector.
