HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: U0100-211, U0100-212, U0100-530, U0129-220, U0129-222, U0129-527, U0129-528, U0140-146, U0151-763, U0164-594, U0164-827, U1107-436: Lost Communication with ECM / PCM "A"
U1107-436 - Lost Communication with Power Management Module

DESCRIPTION

* The power management control ECU (HV CPU) transmits and receives signals via CAN communication to and from the ECM, skid control ECU assembly, power steering ECU assembly, main body ECU, airbag sensor assembly, and air conditioning amplifier assembly.

MONITOR DESCRIPTION

If the power management control ECU (HV CPU) detect problem with CAN communication with the ECU , it will illuminate the MIL and set a DTC.

COMPONENT OPERATING RANGE

CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.

2. Turn the power switch on (IG) and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4. Turn the power switch off.

5. Turn the power switch on (READY) and after a few seconds, turn the power switch off. [A]

6. Repeat [A] 3 times. [B]

7. Turn the power switch on (IG) and turn the Techstream on.

8. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. [C]

9. Check that permanent DTCs are cleared.

10. If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.

HINT
* If a permanent DTC is output, the system is malfunctioning.
* If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (ALL)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Check for DTCs of all systems by following the prompts on the Techstream screen.

(d) Check if DTCs are output.

Result:

(e) Turn the power switch off.
