MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU and airbag ECU detect that a collision has occurred and shut off the system main relay.
The cause of this DTC may be one of the following:
Collision is detected
Detection sensor system malfunction
Airbag system malfunction
Hybrid vehicle control ECU malfunction
Communication malfunction between airbag ECU and hybrid vehicle control ECU
Hybrid vehicle control ECU communication malfunction
The hybrid vehicle control ECU receives a signal that indicates a collision from the airbag ECU assembly to detect a collision. After detecting a collision, the hybrid vehicle control ECU shuts off the high voltage systems for safety.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate | Note |

If P160600 or P160604 is output, the hybrid system cannot be started unless the DTCs are cleared using the GTS.
After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for 30 seconds or more.
With ignition switch to ON (READY) and wait for 30 seconds or more.
Turn the ignition switch off and wait for 30 seconds or more.
Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
Check the DTC judgment result.
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform driving pattern again.
P160600 or P160604 may be output as a result of the malfunction indicated by the DTCs in table below.
