P311 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P3147-240,P3147-242: Transmission Malfunction
P3147-242 - Transmission Malfunction

DESCRIPTION

Refer to the description. P3147





INSPECTION PROCEDURE

CAUTION:
- Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
- After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
HINT
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

PROCEDURE

1. CHECK DTC OUTPUT (HV)

(a) Connect the Techstream to the DLC3.

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

(c) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.

(d) Check if DTCs are output.

Result:

DTCs other than P3147-240 and P3147-242 are output.

YES -- GO TO DTC CHART Hybrid Control System
NO -- Continue to next step.

2. INSPECT CRANKSHAFT PULLEY REVOLUTION (P POSITION)

(a) Turn the power switch on (IG), move the shift lever to the P position, and lift up the vehicle.

(b) Turn the crankshaft pulley using hand tools to check if the crankshaft pulley can rotate.

CAUTION:
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.

NOTICE:
Engine compression causes resistance when turning the crankshaft pulley. Check if the crankshaft rotates smoothly (or if it is locked) by manually applying sufficient torque to turn the crankshaft pulley. The torque required to turn the crankshaft pulley should be the same as for a known good vehicle of the same type.

OK:

The crankshaft pulley rotates.

(c) Lower the vehicle.
