1. FRONT SENSOR AND HARNESS INSPECTION





1) Disconnect connectors (AB4) and (AB5) from airbag control module.
2) Connect connectors (AB4) and (AB5) to connector (8B) of test harness B.
3) Measure resistance between connector (5B) terminals indicated below.

(5B) Terminals / Specified resistance:
(RH: AB4): No.17 - No.18 /1.4 - 1.6 K Ohms
(LH: ABS): No.15 - No.16 /1.4 - 1.6 K Ohms

4) Measure resistance between each connector (5B) terminal and ground.

(5B) Terminals / Specified resistance:
(RH: AB4): No.17 - Body / 1 m Ohms, or more
No.18 - Body / 1 m Ohms or more
(LH: ABS): No.15 - Body / 1 m Ohms, or more
No.16 - Body / 1 m Ohms, or more

2. AIRBAG MAIN HARNESS INSPECTION





1) Disconnect connector (AB6) from airbag control module, and connect (AB6) to test harness B connector (8B).
