DIAGNOSTIC FUNCTION
DIAGNOSIS CODE SET The ETACS-ECU sends diagnosis codes if the communication line is faulty when the MUT-II/III is connected.
Code number | Trouble content
--- | ---
11 | Trouble related to the ETACS-ECU
12 | Trouble related to the column switch or improper communication with the ETACS-ECU
13 | Trouble related to the front-ECU or improper communication with the ETACS-ECU
21 | Short circuit in SWS communication line
31 | Open circuit in the signal line between the SRS-ECU and the ETACS-ECU (impact detection signal)
32 | Short circuit in the signal line between the SRS-ECU and the ETACS-ECU (impact detection signal)
SWS INPUT SIGNAL CHECK BY MUT-II/III
<USING THE MUT-II> When the MUT-II is connected to the diagnosis connector, and switches input for the SWS are operated, the buzzer in the MUT-II sounds, indicating whether the operations of the switches are satisfactory or not.
<USING THE MUT-III> When the MUT-III is connected to the diagnosis connector and any of the SWS-linked switches is operated, the PC buzzer sounds to evaluate whether the switch is normal or not. If the SWS monitor is used for the switch check, the MUT-III (PC) screen will show whether the switch is normal or not. For the details of the input signal check, refer to the Workshop Manual.
<SWS INPUT SIGNAL CHECK AND ECU CHECK BY USING SWS MONITOR> The switch signals sent by ECUs and the operations of these ECUs can be confirmed by using the SWS monitor and the MUT-II/III.
