SRS - Post-collision Diagnosis52B-45
POST-COLLISION DIAGNOSIS
Whether or not the air bags have deployed, check and service
the vehicle after collision as follows:
SRS-ECU MEMORY CHECK
1. Connect the MUT-IIto the diagnosis connector. (Refer
to GROUP 00 – How to Use Troubleshooting/Inspection
Service Points.)
Caution
Refer to that the ignition switch is LOCK(OFF) when
connecting or disconnecting MUT-II.
2. Read (and write down) all displayed diagnosis codes.
(Refer to P.52B-9.)
NOTE
If battery power supply has been shut down by the
collision, the MUT-IIcannot communicate with the
SRS-ECU. Check and, repair if necessary, the instrument
panel wiring harness before the next job.
3. Use the the MUT-IIto read the data list (how long trouble(s)
have continued and how often memory have been
erased).
