READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)

CHECK HARNESS AND CONNECTOR (STARTER RELAY [ST] - ECM)

ECD SYSTEM (w/o DPF) - 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 ().


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 () and initialization ().
  • 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 ().
1.READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)

Connect the intelligent tester to the DLC3.

Turn the ignition switch to ON.

Turn the tester on.

2.CHECK HARNESS AND CONNECTOR (STARTER RELAY [ST] - ECM)

Remove the ST relay from the engine room relay block.

Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.
