System diagnostics
1. Checking the airbag system warning light.
Turn the ignition switch to the "ACC" or "ON" position, check that the indicator lamp comes on and goes out after about 6 seconds.
Note: If the ignition switch is in the ACC or ON position and the indicator light remains on or flashes, check the fault code.
If the indicator light comes on occasionally or remains on even when the ignition switch is in the "OFF" position, check for a short in the indicator light circuit.
2. Reading fault codes.
a) Turn the ignition switch to the "ACC" or "ON" position and wait approximately 20 seconds.
b) Connect the terminals "TWITH" ("11") and "E₁" ("3") of the diagnostic connector.
Note: Incorrect connection of terminals may cause system failure.

c) If there is no fault, the indicator will flash 2 times per second.

d) If there is a malfunction, the indicator will start to flash with a variable frequency. Determine the malfunction codes. The figure shows an example of the output of codes "11" and "31".

3. Clearing fault codes.
a) Set the ignition switch to the OFF (LOCK) position.
b) Connect two wires to terminals "5" (AB) and "11" (TC).
