DTC TableS6RW0D8204003
NOTE
The DTCs (B1022 and B1023) shown with asterisk (*) below have been established only for the M15A
engine model with 4A/T equipped with slip-control (i.e., Hong Kong model). These codes are meant to
be recorded when External Scrapping Deployment Controller is operated by a Japanese authorized
special scrapping trader. Therefore, normally these codes will not appear outside Japan. However,
should these codes be detected, SDM must be replaced because the cause is due to SDM detection
failure.

DTC Detecting Condition and Trouble Area
NOTE
DTC B1013 can never be cleared once it has been set.

DTC Troubleshooting
NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Clear DTCs referring to “DTC Clearance”, if any.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

7Serial communication circuit check
1) With ignition switch turned OFF, disconnect SDM
connector “L04” and check for proper connection at
SDM connector terminal.
2) If connections are OK, check that “Serial data circuit” is
as follows.
• Insulation resistance of “Serial data circuit” wire is
infinity between its terminal and other terminals at
SDM connector.
• Insulation resistance of “Serial data circuit” wire is
infinity between its terminal and vehicle body ground.
Is circuit in good condition?Go to Step 8. Repair or replace
defective circuit.
8Scan tool operation check
1) Check if communication is possible by making
communication with other vehicles.
Is it possible to communicate with the other vehicle?Scan tool is in good
condition, check
intermittent trouble
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.Recheck PCMCIA card
and DLC cable for faulty
condition. If they are
OK, scan tool is faulty. Step Action Yes No

2DTC check
1) Clear DTC referring to “DTC Clearance”.
2) Turn OFF ignition switch.
3) Turn ON ignition switch and check DTC.
Is DTC B1013 still indicated?Go to Step 3. Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
3SDM power supply and ground circuit check
1) Check SDM power supply and ground circuit referring to
“SDM Power Supply and Ground Circuit Check”.
Is SDM power supply and ground circuit in good condition?Substitute a known-
good SDM and recheck.Repair power supply
and ground circuit.
