Check items Display Remarks
H)Error 1
(Bit 0 - Bit 3)
SEL441X
The segment of each bit displays ª0º, meaning no failure.
If the bit(s) displays figures other than ª0º, the item of the
bit has failed.
For details, refer to ªFailure chart for Error 1 and Error Eº
below.
I)Error E
(Bit 4 - Bit 7)

Bit Detectable items Description of the failureDisplayed figure on the
bit
Failure No failure
0Speedometer input sig-
nalNo input signal
When no signal is detected for 30 minutes continuously with
the ignition ON, it should be judged as signal failure.
(If input signal is detected later, then the judgement will be
canceled immediately.)1
0
Abnormal input signal
When any signal of frequency which would not exist in normal
conditions is detected, it should be judged as signal failure.2
1Tachometer input signal No input signal
When no signal is detected for 30 minutes continuously with
the ignition ON, it should be judged as signal failure.
(If input signal is detected later, then the judgement will be
canceled immediately.)1
0
Abnormal input signal
When any signal of frequency which would not exist in normal
conditions is detected, it should be judged as signal failure.2
