T1 |
low |
MEMO Signal – the falling
edge
triggers three, short beeps at a rate of 1.6 Hz. More follow if T1 is held low
(remains grounded). |
T2 |
low |
LIMIT and TEMP Warnings – the
falling edge triggers the first chime. More follow repeating at 0.6 Hz if T2 is
held low. |
T3 |
low |
American Key-in-Ignition Warning
– the
falling edge starts the chime. The tone continues if T3 is held
low. The tone fades away over 1.6 s when T3 is taken high. T3 ignores
pulses shorter than roughly 20 ms (40 ms always works). |
T4 |
low |
Park Distance Control –
grounding T4 makes an immediate, quieter, continuous, high pitched tone. |
T5 |
high |
Japanese Reverse Warning – a
lower pitched, sublime ping similar to T2. Holding T5 high (at
12V) makes
repeated pings after a brief delay. |
