Toyota Corolla Cross: Collision detected or Collision Sensor Connection (Open) (P160600,P160604)
DTC SUMMARY
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
DESCRIPTION
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.

HINT:
If P160600 or P160604 is output, the hybrid system cannot be started unless the DTCs are cleared using the GTS.
CONFIRMATION DRIVING PATTERN
HINT:
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.
HINT:
- 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.
CAUTION / NOTICE / HINT
HINT:
P160600 or P160604 may be output as a result of the malfunction indicated by the DTCs in table below.
