Component Location

General Description

SRSCM (Supplemental Restraints System Control Module) checks input voltage when "IG ON" to make air bag system work properly.

If input voltage is out of normal range, there can be malfunction in system operation. In this case, Check battery and charging system.

DTC Description

The SRSCM sets DTC B1101 and turns warning light on if voltage above threshold value is detected for more than 4 sec.

(If voltage within threshold value is detected When the SRSCM returns to normal condition. SRSCM regards DTC as being cleared and turns warning light off).

DTC Detecting Condition

Item		Detecting Condition	Possible cause
DTC Strategy		• Check voltage	1. Poor connection of connected part. 2. Open/Short circuit in power harness. 3. Open/Short circuit in ground harness. 4. Faulty charging system. 5. Faulty SRSCM.
Enable Conditions		• Ignition "ON"
Threshold Value		• Vbatt ≥ 16
Diagnostic Time	Qualification	• More than 4 sec
	De-Qualification	• More than 4 sec

Specification

Test Condition	Voltage
Idle & WOT	Approx. 8 ≤ Vbatt ≤ 16
