NO: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
4. Check if DTCs are output.

   Result

   Result	Proceed to
   DTC P3147-240 or P3147-242 is output.	A
   DTC P0A1D is output.	B
   DTCs other than P3147-239 or P3147-241 are not output.	C

B → GO TO INSPECTION PROCEDURE RELEVANT TO OUTPUT DTC (P0A1D) 

A → See step   12 

C: Go to next step 

1. Turn the power switch off, move the shift lever to the P position, and lift up the vehicle.
2. Turn the crankshaft pulley using hand tools to check if the crankshaft pulley can rotate.
   WARNING:

   Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.

   OK

   The crankshaft pulley rotates.

NG → See step   11 

OK: Go to next step 

1. Disconnect connector E83 from the the ECM.
2. Disconnect the crankshaft position sensor connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for open)

   Tester Connection	Specified Condition
   NE+ (E83-69) - NE+ (E47-1)	Below 1 Ω
   NE- (E83-68) - NE- (E47-2)	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connection	Specified Condition
   NE+ (E83-69) - NE+ (E47-1) - Body ground	10 kΩ or higher
   NE- (E83-68) - NE- (E47-2) - Body ground	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Check for HV system DTCs, freeze frame data, and diagnostic information and note them down.

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Read and record the DTCs and freeze frame data.
4. Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
5. Clear the DTCs.

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Select the following menu items: Powertrain / Hybrid Control / Data List / Generator (MG1) Rev, Engine Revolution.
4. Read the data list.
5. Turn the power switch on (READY).

   OK

   The READY light comes on.

   HINT: 

   If the READY light does not come on and the reading on the Techstream shows DTC P3147-239 (hybrid vehicle transmission input malfunction [shaft damaged]), or if the READY light comes on and MG1 turns but the engine does not crank, replace the hybrid vehicle transmission assembly.

NG → See step   12 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Select the following menu items: Powertrain / Hybrid Control / Data List / Generator (MG1) Rev, Engine Revolution.
4. Read the data list.
5. Turn the power switch on (READY).
6. While the READY light is on, fully depress the accelerator pedal for 10 seconds with the shift lever in the P position.

   OK

   The engine revs up.

   HINT: 

   If the engine does not rev up and the reading on the Techstream shows DTC P3147-239 (hybrid vehicle transmission input malfunction [shaft damaged]), or if MG1 turns but the engine does not crank, replace the hybrid vehicle transmission assembly.

NG → See step   12 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Depress the brake pedal, move the shift lever to the D position, and release the brake pedal.

   OK

   The wheels turn (creeping along).

   HINT: 

   If the wheels do not turn and the reading on the Techstream shows DTC P3147-239, replace the hybrid vehicle transmission assembly.

NG → See step   12 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. While driving at a vehicle speed of more than 10 km/h, fully depress the accelerator pedal to raise the engine speed.
   NOTE:

   Perform this test only in an appropriate safe location, in accordance with all local laws.

   OK

   Engine speed increases smoothly.

   HINT: 

   If the engine over-revs or the reading on the Techstream shows DTC P3147-239, replace the hybrid vehicle transmission assembly.

NG → See step   13 

OK → See step   14 

1. Turn the power switch off and move the shift lever to the N position.
2. Lift up the vehicle.
3. Turn the crankshaft pulley using hand tools to check if the crankshaft pulley can rotate.
   WARNING:

   Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.

   OK
