PRE±CHECK
1. TRANSPONDER KEY ECU INPUT CONDITION DIS-
PLAY READ CODE
(a) Connect the positive (+) lead from the volt meter (Analog
Type) to OP1 of the check connector and the negative (±)
lead to E1 of the check connector.
(b) Insert the ignition key in the key cylinder.
(c) Read the code from the movement of the tester needle.
If no code is output, turn the ignition switch ON.
If a code is now output, check if the DOME fuse is blown.
HINT:

The code can be read using a luminous diode (Recom-
mend activation current 10 ± 20 mA) instead of a tester.

A digital tester can also be used.
Display condition:

When there are multiple codes, they are output in order
staring from the lowest code.

After all the codes are output, Lo is displayed for 4.5
secs., then all the code are output again starting from the
lowest code.

If the situation changes during code output, Lo is output
for 4.5 secs. after output of the current code ceases, then
the codes are output again starting from the lowest code.
E.g. while 11 (out of 11 and 21) is being output, conditions
change and 12 is added. So after 11 is output, Lo is output
for 4.5 secs., then 11, 12 and 21 are output.
