DIAGNOSTIC TROUBLE CODE CHART
If a DTC is displayed during the DTC check, check the circuit
listed for the DTC in the table below (refer to the appropriate
page).
HINT:
• When the SRS warning light remains on and the normal
system code is output, a decrease in the source voltage is
likely to occur. This malfunction is not stored in the
memory of the center airbag sensor. If the power source
voltage returns to normal, the SRS warning light will
automatically go off.
• When 2 or more DTCs are indicated, the DTC with the
lowest number appears first.
• If a DTC is not listed on the DTC chart, the center airbag
sensor may have malfunctioned.
• In the case of any malfunctions concerning open circuits,
shorts to ground, or shorts to B+ due to squibs, other
DTCs may not be set. In this case, repair the malfunction
currently indicated and then perform a malfunction
diagnosis again.
• Mark in the check mode column:
-: DTC does not correspond to check mode.
: DTC corresponds to check mode.
• When DTC B1650/32 is set as a result of troubleshooting
the Supplemental Restraint System (SRS), perform
troubleshooting for the occupant classification system.

HINT:
Connect the cable of the intelligent tester (with CAN
VIM) to the DLC3, turn the ignition switch ON and
attempt to use the intelligent tester. If the screen displays
UNABLE TO CONNECT TO VEHICLE, a problem exists
in the vehicle side or the tester side.
If the communication is normal when the tester is
connected to another vehicle, inspect the DLC3 on the
original vehicle.
If the communication is still not possible when the tester
is connected to another vehicle, the problem is probably
in the tester itself. Consult the Service Department listed
in the tester's instruction manual.
DTC CHECK / CLEAR
1. CHECK DTC
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON and turn the intelligent
tester ON.
(c) Select the following menu items: DIAGNOSIS /
OBD/MOBD / IMMOBILISER / DTC INFO /
CURRENT CODES.
(d) Check DTCs and then write them down.
HINT:
Refer to the intelligent tester operator's manual for
further details.
(e) Confirm the details of the DTCs (see page EI-20).
2. CLEAR DTC
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON (do not start the engine)
and turn the intelligent tester ON.
(c) Select the following menu items: DIAGNOSIS /
OBD/MOBD / IMMOBILISER / DTC INFO / CLEAR
CODES.
HINT:
Refer to the intelligent tester operator's manual for
further details.
(d) Erase DTCs by pressing the YES button on the
tester.

mode to allow the vehicle to be driven temporarily.
HINT:
*: The vehicle can be driven slowly when the accelerator
pedal is depressed firmly and slowly. If the accelerator pedal
is depressed quickly, the vehicle may speed up and slow
down erratically.
