Hold the pawl side connector half. and press on the
back of the sleeve-side connector halt in the direction
shown. As the two connector halves are pressed
together, the sleeve is pushed back by the pawl.
NOTE: Do not touch the sleeve.
7.When the connector halves are completely connected.
the pawl is released. and the spring loaded sleeve
locks the connector.

Attach the connector in the holder, then install the
access panel on the stee.ing wheel lower cover.
Connect the positive cable first. then the negative
cable to the battery.
After installing the airbag assembly, confirm proper
system operation:
. Turn the ignition switch ON (ll); the instrument
panel SRS indicator light should come on for
about six seconds and then go off.
. Confirm operation of horn buttons.
. Confirm operation of cruise control sevresume
switches.

Troubleshooting Precautions
ABS lndicator
1. lf the system is OK. the ABS indicator goes off two seconds after turning the ignition switch ON (ll) without starting
the engine, and then comes on again and goes off after two seconds. This occurs because the ABS control unit is
turned on bv the lG2 oower source.
2. The ABS indicator comes on when the ABS control unit detects a problem in the system. However, even though the
system is operating properly, the ABS indicator will come on under the following conditions.. Onlv drive wheels rotate
. One drive wheel is stuck
. Vehicle spin
. ABS continues to operate for a long time
. Signal disturbance
To determine the actual cause of problem. question the customer about the problem, taking these conditions into
consideration.
3. When a problem is detected and the ABS indicator comes on, there are cases when the indicator stays on until the
ignition switch is turned OFF, and cases when the indicator goes off automatically when the system returns to nor-
mal. For DTCS 61 and 62, the indicator goes off automatically when the system returns normal. For all other codes.
the indicator stays on until the ignition switch is turned OFF.
4. For DTCS 12, 14, 16, '18, 2'1,22, 23, 24,51,52 and 53, the indicator goes off when the vehicle is driven again and the
system is OK after the ignition switch is turned from OFF to ON (ll). However, if the DTC is erased, the CPU is reset
and the indicator goes off right after the engine is started if the system is OK.
Diagnostic Trouble Code (DTC)
1. lf the CPU cannot be actlvated and the indicator comes on, the DTC is not memorized.
2. The memory can hold any number of DTCS. However, when the same DTC is detected more than once, the later one
is written over the old one. Therefore, when the same problem is detected repeatedly, it is memorized as one DTC.
3. The DTCs are indicated in the order of ascending number, not in the order they occur.
4, The DTCS are memorized in the EEPROM (non-volatile memory). Therefore, the memorized DTCS cannot be canceled
by disconnecting the battery. Perform the specified procedures to erase the DTCS,
S6lt-dirgnosis
1. Self-diagnosis can be classifield into two categories.
. Initial diagnosis: Performed right afterthe enginestansand untiltheABS indicator goes off.. Regular diagnosis: Performed rightafterthe initial diagnosis untilthe ignition switch isturned OFF.
2. When a problem is detected by self-diagnosis, the system
. Turns the fail-safe relay OFF
. Turns the solenoid valve OFF
. Turns the oumo motor OFF
. Turns the ABS indicator ON
