1. DESCRIPTION The power management control ECU has a self-diagnosis system. If the computer, hybrid control system, or a component is not working properly, the ECU records the conditions that relate to the fault. The ECU also illuminates the master warning light in the combination meter assembly and provides other appropriate messages on the multi-information display, such as the HV system warning message, the HV battery warning message, on the discharge warning message. TEXT IN ILLUSTRATION *1 READY Light *2 Multi-information Display *3 Master Warning Light *4 MIL *5 Auxiliary Battery Charging Warning Light - - HINT: The master warning light will illuminate when the hybrid control system malfunctions and the light will blink when in inspection mode. When troubleshooting OBD II (On-Board Diagnostics) vehicles, the Techstream (complying with SAE J1987) must be connected to the DLC3 (Data Link Connector 3) of the vehicle. Various data in the vehicle ECM (Engine Control Module) can then be read. OBD II regulations require that the vehicle's on-board computer illuminate the MIL (Malfunction Indicator Lamp) on the instrument panel when the computer detects a malfunction in: The emission control system components. The powertrain control components (which affect vehicle emissions). The computer itself. In addition, the applicable DTCs prescribed by SAE J2012 are recorded in the power management control ECU memory. If the malfunction does not recur in 3 consecutive trips, the MIL turns off automatically but the DTCs remain recorded in the power management control ECU memory. To check for DTCs, connect the Techstream to the DLC3. The Techstream displays DTCs, freeze frame data, and a variety of hybrid control system data. The DTCs and freeze frame data can be cleared with the Techstream. In order to enhance the OBD function on vehicles and develop the Off-Board diagnosis system, Controller Area Network (CAN) communication is used in this system. CAN is a network which uses a pair of data transmission lines spanning multiple computers and sensors. It allows for high speed communications between the systems and simplification of the wire harness connections.
2. 2 TRIP DETECTION LOGIC When a malfunction is first detected, the malfunction is temporarily stored in the power management control ECU memory (1st trip). If the same malfunction is detected during the next drive cycle, the MIL is illuminated (2nd trip).
3. FREEZE FRAME DATA The power management control ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, as well as other data recorded at the time of a malfunction.
4. AUXILIARY BATTERY VOLTAGE Standard Voltage Switch Condition Specified Condition Ignition switch ON (IG) 11 to 14 V If voltage is below 11 V, replace or recharge the auxiliary battery. NOTE: After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work. Refer to «PRECAUTION [12/2013 - ]»(ref-651169-S11524377852014081900000) .
5. MIL (Malfunction Indicator Lamp) The MIL is illuminated when the ignition switch is first turned on (IG), before the READY indicator comes on. When the READY indicator turns on, the MIL should turn off. If the MIL remains illuminated, the diagnosis system has detected a malfunction or abnormality in the system. HINT: If the MIL is not illuminated when the ignition switch is first turned on (IG), check the MIL circuit. Refer to «MIL Circuit [12/2013 - ]»(ref-651307-S07652644952014081900000) .

Select the item from among Information 1 to Information 5 that has an information code and click the engine icon to view the additional information.
3. CHECK FOR DTCS (SYSTEMS OTHER THAN POWER MANAGEMENT CONTROL ECU) HINT: The power management control ECU maintains communication with other computers, including the ECM, skid control ECU and power steering ECU. Therefore, if the power management control ECU outputs a warning, it is necessary to check and record the DTCs of all systems. If DTCs are present, check the relevant systems. HINT: If DTCs for the CAN communication system are present in addition to other DTCs, first troubleshoot and repair any malfunctions in the CAN communication system.
4. CLEAR DTCS NOTE: Clearing the DTCs will also clear the freeze frame data, information. Refer to «INFORMATION / FREEZE FRAME DATA [12/2013 - ]»(ref-651326-S10752234802014081900000) , and operation history data.

Check if permanent DTCs are stored. HINT: If permanent DTCs are not output, it is not necessary to continue this procedure. Clear the DTCs. Perform the respective confirmation driving patterns in order to obtain a normal judgment for the output DTCs. HINT: Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs. For the confirmation driving pattern, refer to the procedures for the relevant DTC. Refer to «DIAGNOSTIC TROUBLE CODE CHART [12/2013 - ]»(ref-651311-S37049002362014081900000) . Perform the universal trip. HINT: The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle. Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE [12/2013 - ]»(ref-651169-S20116998062014081900000) . Idle the engine for 30 seconds or more. Drive the vehicle at 40 km/h (25 mph) or more for a total of 5 minutes or more. HINT: It is possible to complete the drive pattern even if the vehicle decelerates to less than 40 km/h (25 mph) during the driving cycle provided that the vehicle is driven at 40 km/h (25 mph) or more for a total of 5 minutes. Allow 10 minutes or more to elapse from the time the engine is started. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. Check that the permanent DTCs have been cleared. HINT: The permanent DTCs are cleared when the universal trip is completed.

DATA LIST / ACTIVE TEST [12/2013 - ]

1. DATA LIST NOTE: Some Data List values may vary significantly if there are slight differences in the environment in which the vehicle is operating when measurements are obtained. Variations may also occur due to aging of the vehicle. Due to these considerations, it is not always possible to provide definite values to be used for judgment of malfunctions. It is possible that a malfunction may be present even if measured values are within the reference range. In the event of a problem with intricate symptoms, collect sample data from another vehicle of the same model operating under identical conditions in order to reach an overall judgment by comparing all the items in the Data List. Connect the Techstream to the DLC3. Turn the ignition switch to ON (IG). Turn the Techstream on. Enter the following menus: Powertrain / Hybrid Control / Data List. Check the results by referring to the following table. HINT: When reviewing Data List information, try to select only the specific Data List items related to the inspection being performed.

2. ACTIVE TEST Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data list information can be displayed while performing Active Tests. NOTE: It is necessary to use caution, because if the tester DLC connector becomes disconnected or if a communication error occurs during an Active Test, the vehicle could become inoperative (the READY indicator may go off). After performing the Active Test, turn the ignition switch off before proceeding to the next step. Connect the Techstream to the DLC3. Turn the ignition switch to ON (IG). Turn the Techstream on.
