DESCRIPTION
The forward recognition camera controls the current supplied to the camera heater (forward recognition hood).
If the forward recognition camera detects a malfunction in the camera heater (forward recognition hood) circuit, DTC C1AAE is stored.

PROCEDURE
1. INSPECT CYLINDER BLOCK FOR WARPAGE
(a) Using a precision straightedge and feeler gauge, measure the warpage
of the contact surface of the cylinder head gasket.
Standard warpage:
0 to 0.05 mm (0 to 0.00197 in.)
Maximum warpage:
0.07 mm (0.00276 ...
Check Mode Procedure
CHECK MODE PROCEDURE
1. DESCRIPTION
(a) Check mode has a higher sensitivity to malfunctions and can detect malfunctions
that normal mode cannot detect. Check mode can also detect all the malfunctions
that normal mode can detect. In check mode, DTCs are detected with 1 trip detection
logic.
...
Additional Key cannot be Registered
DESCRIPTION
If additional registration is not possible, a malfunction in the certification
ECU (smart key ECU assembly), engine switch, electrical key transmitter sub-assembly
or steering lock ECU (steering lock actuator or UPR bracket assembly) is suspected.
