Control Module Performance

Either condition is met (1 trip detection logic):

  • Decrease in ECM supply voltage resulting in insufficient voltage to DC motor (turbocharger sub-assembly)circuit.

  • Decrease in ECM supply voltage resulting in insufficient voltage to EGR valve circuit.

  • ECM power supply circuit

  • ECM

Comes on / Does not come on*

*: Depending on the detection condition.

CAUTION / NOTICE / HINT

Note:

  • When replacing the ECM, the ECM needs registration and initialization.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Tip:

  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE

  1. CHECK HARNESS AND CONNECTOR

    1. Disconnect the negative (-) battery terminal

    2. Disconnect the positive (+) battery terminal

    3. Disconnect the ECM connector.

    4. Remove the EFI MAIN NO. 1 relay from the engine room relay block and junction block.

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