3 Check center airbag sensor assembly. Center Airbag Sensor Assembly Spiral Cable Steering Wheel Pad (Squlb) D+ D- ACC ON E1 Tc Code 15 AB0034 AB0013 AB0015 AB0014 P (1) Connect connector to center airbag sensor assembly. (2) Using a service wire, connect D+ and D- on spiral cable side of connector between spiral cable and steering wheel pad. (3) Connect negative (—) terminal cable to battery, and wait at least 2 seconds. C (1) Turn ignition switch ACC or ON, and wait at least 20 seconds. (2) Using SST, connect terminals Tc and E1 of check connector. SST 09843-18020 (3) Check diagnostic code. OK Diagnostic code 15 is not output. Hmm Codes other than code 15 may be output at this time, but this is not relevant to this check. NG Replace center airbag sensor assembly. OK From the results of the above inspection, the malfunctioning part can now be considered normal. To make sure of this, use the simulation method to check. 4 Check front airbag sensor. P Disconnect front airbag sensor connector. C Measure resistance between each terminal of front airbag sensor. +A +S -S -A AB0034 OK Terminal | Resistance ⊙S - ⊙A | 755Ω - 885Ω ⊙S - ⊙S | ∞ ⊙S - ⊙A | Less than 1Ω Notice • Do not touch ohmmeter probes strongly against terminals of front airbag sensor. • Make sure the front airbag sensor connector is properly connected.
