ON-BOARD DIAGNOSTIC QUICK REFERENCE CHART
Fault No.
Normal. The SRS is in good order.
11 The circuits for the front impact sensor are shorted to each other.
Or the negative harness between the air bag module and the SDU
is shorted to ground or the positive harness between the front im-
pact sensor and the SDU is shorted to ground.
12 Right or left impact sensor circuit is open or the wire from the sen-
sor to the SDU is open-circuit.
Right and left impact sensor circuits are open or the wires from the
13
sensors to the SDU are open-circuit.
21 The circuits for the driver's air bag module (squib) are shorted to
each other or the circuit is grounded.
The driver's seat air bag module (squib) circuit is open or the wire
22
from the driver's air bag module to the SDU (clock spring) is open-
circuit. Or the harness connector make a poor contact or the posi-
tive harness between the driver's air bag module and the SDU is
shorted to ground.
24 The circuits for the passenger's air bag module (squib) are
shorted to each other or the circuit is grounded.
25 The passenger's air bag module (squib) circuit is open or the wire
from the passenger's air bag module to the SDU (clock spring) is
open-circuit. Or the harness connector make a poor contact or the
positive harness between the passenger's air bag module and the
SDU is shorted to ground.
31 The capacitor (integrated in the SDU) terminal voltage is higher
than the specified value for 5 seconds.
The capacitor (integrated in the SDU) terminal voltage is lower
than the specified value for 5 seconds. Or the battery runs short.
The circuit for the cranking signal is shorted to some power supply
circuits. It takes at least 45 seconds that the SDU detects this
fault.

If the battery voltage is normal, re-
place SDU. (Refer to P.52B-71.)
If the battery is run down, turn the
ignition key to the "LOCK" position,
disconnect the negative battery
cable and wrap the terminal with
tape for insulation. Then, charge
the battery.
