DTC 66

DIAGNOSIS: ELR with pretensioner (LH) circuit is shorted to power supply.

CAUTION: Before performing diagnostics on airbag system, turn ignition switch "OFF", disconnect battery ground cable and then wait at least 20 seconds.

5Y1: ELR WITH PRETENSIONER INSPECTION
1. Disconnect connector (AB21) from ELR with pretensioner LH side, and connect (AB21) to test harness F connector (1F).
2. Connect airbag resistor to test harness F connector (3F).
3. Connect battery ground cable and then turn ignition switch to ON (engine off). Observe airbag warning light.

CHECK: Does the airbag warning light come on for about 7 seconds, then go out and stay out?

YES: Replace ELR with pretensioner LH side.

NO: Go to step 5Y2.

5Y2: SIDE AIRBAG HARNESS SHORTED TO POWER SUPPLY CIRCUIT INSPECTION
1. Turn ignition switch OFF, disconnect battery ground cable and then wait at lest 20 seconds.
2. Disconnect side airbag connector LH side (AB19) and (AB20). (Side airbag equipped vehicle)
3. Disconnect connector (AB17) from airbag control module, and connect (AB17) to test harness I or I2 connector (1I).
4. Connect battery ground cable and then turn ignition switch ON (engine off).




5. Measure voltage between test harness I or I2 connector (3I) terminal and chassis ground.

CHECK: Is the voltage less than 1 V?

YES: Go to step 5Y3.

NO: Replace side airbag harness.

5Y3: SIDE AIRBAG HARNESS SHORTED TO POWER SUPPLY CIRCUIT INSPECTION




Measure voltage between test harness I or I2 connector (3I) terminal and chassis ground.

CHECK: Is the voltage less than 1 V?

YES: Replace airbag control module.

NO: Replace side airbag harness.
