DESCRIPTION
The multi-information display is built into the combination meter assembly.
When there is a malfunction in the pop up hood (including disconnection of a connector) or the pedestrian protection sensors detects a pressure higher than the specified value, the airbag sensor assembly sends a signal via CAN communication to display "POP UP HOOD Failure." on the multi-information display to inform the driver of the malfunction.
The airbag sensor assembly also sends a signal via CAN communication to display "POP UP HOOD Activated." on the multi-information display to inform the driver of pop up hood lifter operation.
If a malfunction occurs in the combination meter assembly, airbag sensor assembly or wire harness connected to the airbag sensor assembly or combination meter assembly, "POP UP HOOD Activated." or "POP UP HOOD Failure." remains displayed on the multi-information display.

CAUTION / NOTICE / HINT
Note
After turning the power 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.
Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
CHECK MULTI-INFORMATION DISPLAY OPERATION
Turn the power switch on (IG) and check the display status of "POP UP HOOD Activated." and "POP UP HOOD Failure.".
Tech Tips
The primary check is performed for approximately 6 seconds after the power switch is turned on (IG).
