. Remove dashboard.
Remove heater unit. Check if SAS unit connector is securely connected. If not, reconnect connector and
go next step. If ok, go to next step.
2. Disconnect SAS unit connector and check for continuity between terminal No. V and terminal No. Y of
SAS unit connector. If there is continuity, replace SAS unit. If there is no continuity, replace wiring
harness. Perform SYSTEM OPERATION CHECK
.
DTC 3 - BATTERY
1. Check that battery voltage is at least 8 volts. If not, check battery and/or charging system. Turn ignition
on and check voltage at joint connector terminals A or E (X-33).
2. If voltage is over 8 volts, replace SAS unit. See SAS UNIT
under REMOVAL & INSTALLATION. If
voltage is not over 8 volts, replace wiring harness from battery to fuse box. Perform SYSTEM
OPERATION CHECK .
DTC 6 - DRIVER-SIDE AIR BAG MODULE
1. Disable air ba
g system. See procedures under DISABLING & ACTIVATING AIR BAG SYSTEM. NOTE: When air bag warning light remains on, it can indicate a DTC 0 caused by no
continuity between terminal No. V and terminal No. Y of SAS unit This can be
due to a damaged SAS unit, an open or short circuit in wiring harness or poor
connections.
NOTE: For connector terminal identification, see WIRING DIAGRAM
.
NOTE: When voltage supplied to SAS unit is less than 1 volt due to weak battery, open
or short in wiring harness, poor connection of connector or damaged SAS unit,
DTC 3 will set
NOTE: For connector terminal identification, see WIRING DIAGRAM
.
NOTE: When resistance Is detected between terminals M-O of SAS unit is NOT 2 ohms,
