Supplemental restraint system--Repair
Repair.................................................................
a. In using process, if happening any malfunction of power supply, it shows the voltage of power supply
is less than 9V or higher than 18V, or the battery is damaged, at this time, it only needs to charge or
change the battery.
b. Use special malfunction diagnostic tool to test.
