3. With squib circuit connector disconnected, insert paper into female terminal, sliding it under shorting bar
spring. This lifts the spring, breaking the circuit and allowing the test procedure to be performed as
specified.
TESTING - DIAGNOSTIC
NO CODES - SOURCE VOLTAGE DROP
1. Disconnect negative battery cable. Wait at least 90 seconds. Remove steering wheel pad. See
STEERING WHEEL PAD & SPIRAL CABLE
under REMOVAL & INSTALLATION. Disconnect
passenger-side air bag harness connector, accessible through finish plate in glove box. See Fig. 2
.
Disconnect air bag sensor assembly connector.
2. Reconnect negative battery cable. Turn ignition switch to ON position. Measure voltage between ground
and terminals IG2 and ACC of air bag sensor connector. See Fig. 13
. Operate electrical components
(defogger, wiper, headlights, heater blower, etc.). If voltage is 8-14 volts, go to next step. If voltage is not
8-14 volts, check harness between battery and air bag sensor assembly and check battery and charging
system.
3. Turn ignition switch to LOCK position. Connect steering wheel pad connector. Connect passenger-side
air bag connector. Turn ignition switch to ON position. Operate electrical components as in step 2) and
check that SRS warning light goes off. If light does not go off, check diagnostic trouble code and go to
appropriate CODE under TESTING - DIAGNOSTIC. If a normal code is output, replace air bag sensor
assembly. If warning light goes off, no problem detected at this time.
CODE 11
1. Disconnect negative battery cable. Wait at least 90 seconds. Remove steering wheel pad. See
STEERING WHEEL PAD & SPIRAL CABLE
under REMOVAL & INSTALLATION. Disconnect
passenger-side air bag harness connector, accessible through finish plate in glove box. See Fig. 2
.
Disconnect air bag sensor assembly connector.
2. Measure resistance on spiral cable side of connector between spiral cable and steering wheel pad between
D+, D- and ground. If resistance is 1000 ohms or more, go to next step. If resistance is less than 1000
ohms, go to step 7).
3. Measure resistance on air ba
g sensor assembly side of connector between air bag sensor and passenger- WARNING:Paper must not be thicker than male terminal. If paper is thicker,
connector terminal may be damaged, possible resulting in system
fault.
NOTE: Use Diagnosis Check Wiring (09843-18020) when connecting jumper wire
between terminals of DLC. Spiral cable upper connector is same as steering
wheel pad (squib) connector. Spiral cable lower connector (located under
steering column) connects the harness between spiral cable and center air bag
sensor.
NOTE: During testing, if codes other than Code 11 are displayed, disregard them.

When DLC1 terminals Tc and E1 are connected together, air bag sensor assembly is set in Diagnostic Trouble
Code (DTC) output mode. DTC is displayed by flashing AIR BAG warning light.
Diagnostic Procedure
1. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds.
Access and disconnect air bag sensor assembly connector C20 (center connector). See AIR BAG
SENSOR ASSEMBLY under REMOVAL & INSTALLATION
.
2. Measure resistance between ground and air bag sensor assembly connector C20, terminal No. 19 (circuit
Tc, Pink/Black wire). See Fig. 16
. If resistance is more than one megohm, replace air bag sensor
assembly. If resistance is less than one megohm, replace harness and connector.
SOURCE VOLTAGE DROP
Description
The air bag sensor assembly is equipped with a voltage-increase circuit to allow system operation in case source
(battery) voltage drops below minimum. When battery voltage drops, voltage-increase circuit functions to
increase voltage of air bag system to normal voltage.
The malfunction display for this circuit is different from other air bag system circuits. When source voltage
drop is detected and no other DTCs are present, the AIR BAG warning light remains illuminated constantly.
Source voltage drop is not recorded in air bag sensor assembly as a malfunction, and when source voltage
returns to normal, AIR BAG warning light will turn off.
Diagnostic Procedure
1. Turn ignition switch to LOCK position. Disable air bag system. See DISABLING SYSTEM under
DISABLING AND ACTIVATING AIR BAG SYSTEM. Reconnect negative battery cable.
2. Turn ignition switch to ON position. Turn on electrical accessories (defogger, wipers, headlights, blower
motor, etc.). Measure voltage between ground and air bag sensor assembly connector C20, terminals No.
5 (circuit IG2, Black/Orange wire) and No. 6 (circuit ACC, Gray wire). See Fig. 16
. Turn electrical
accessories off. If voltage is 10-14 volts, go to next step. If voltage is not 10-14 volts, check harness
between battery and air bag sensor assembly and check battery and charging system.
3. Turn ignition switch to LOCK position. Activate air bag system. See ACTIVATING SYSTEM
under
DISABLING & ACTIVATING AIR BAG SYSTEM. Turn ignition switch to ON position. Turn on
electrical accessories again. If AIR BAG warning light goes out, system operation is normal at this time.
If AIR BAG warning light does not go out, check for DTCs. See RETRIEVING CODES
under
DIAGNOSIS & TESTING. If DTC is displayed, go to appropriate DTC. If a normal code is displayed (2
flashes per second), replace air bag sensor assembly.
DTC 11/B0102: DRIVER-SIDE AIR BAG SQUIB CIRCUIT SHORT TO GROUND
Description
The driver-side air bag squib circuit consists of the air bag sensor assembly, spiral cable and driver-side air bag
module. The squib causes drive
r-side air bag to deploy when all deployment conditions are satisfied.

LOAD TEST
1. Connect an ammeter as described in NO
-LOAD TEST , step 1) . See Fig. 2 . Start engine. Turn on high
beam headlights and place heater blower control on HI. Increase engine speed to 2000 RPM.
2. Check ammeter reading. Ammeter should read 30 amps or more. If amperage is less than specified, repair
or replace generator.
BENCH TESTING
BRUSHES
1. Brushes should slide smoothly in holders. Replace brushes if damaged or worn. On Tundra and 4Runner,
new brush exposed length should be .374-.453" (9.5-11.5 mm). On all other models, new brush exposed
length should be .413" (10.5 mm).
2. On all models, minimum exposed length should be more than .059" (1.5 mm). There are 2 different brush
holders used. One brush holder is replaced as an assembl
y, and the other has replaceable brushes. If
NOTE: If battery is fully charged, disable ignition system. Crank engine for about 15
seconds to partially discharge battery.
NOTE: If battery is fully charged, generator load test results may be less than 30 amps.
