1. Do Not use multimeter or any equipment with power source to check the wiring
of Airbag squib circuits.
3. Before disconnecting the Airbag / Pretensioner units, the ignition switch should be OFF.
4. Do Not short the Airbag system terminations with either vehicle battery supply or ground
or external power source which will damage the system.
IMPORTANT NOTES:
2. Use only Diagnostic software provided to ensure proper connectivity of Airbag System.
The software is capable of detecting any error in wiring connectivity and loop resistance
(Refer table attached for limit values).

CHECK THE LHS PRETENSIONER POSITIVE
LINE FOR ISOLATION FROM POWER SRSE1
Deactivate the Airbag system. (Follow the procedure given in the Deactivation sheet.)
Turn the ignition key to ON position.
Measure the voltage between:
(+) Red Probe of Multimeter
Vehicle Battery
(-) Black Probe of Multimeter
Airbag Simulator, Fitted in LHS Pretensioner
Positive terminal
Red Colour extension
Is the voltage more than 3.7 V?
YES
GO to SRSE2
No

Is the voltage more than 3.7 V?
YES
An intermittent fault may be present in the wiring
harness. Visually check for chaffed wires or other
physical damage to the harness. If no fault is found
in the circuit, suspect the following component(s):
a) LHS Pretensioner connector.
b) Airbag module connector.
c) Floor Interconnector
d) LHS Pretensioner assembly.
e) Airbag module.
No
GO to SRSE4

Positive terminal Pin 1 - RHD
Is the voltage more than 3.7 V?
YES
Replace the Floor wiring harness and reactivate the
system.
(Refer to Reactivation sheet.)
NO
Replace both the Floor and CCB wiring harness and
reactivate the system.
(Refer to Reactivation sheet.)
