Dtc B1513 (No.13): Temperature Control Actuator And/Or Its Circuit Malfunction - Suzuki Liana RH413 Service Manual

Step
3 1) Check resistance between "RED/WHT" wire terminal
and body ground.
Is resistance more than 1 M
4 1) With ignition switch ON position, check voltage between
"RED/WHT" wire terminal and "BLK/RED" wire terminal
at air flow control actuator connector.
Is voltage about 5 V?
5 1) With ignition switch ON position, check voltage between
"WHT/BLU" wire terminal and "BLK/RED" wire terminal
at air flow control actuator connector.
Is voltage about 5 V?
6 1) Turn ignition switch OFF, disconnect HVAC control
module connector referring to "HVAC Control Module
Removal and Installation in Section 7A".
2) Check resistance between "WHT/BLU" wire terminal at
air flow control actuator connector and "WHT/BLU" wire
terminal at HVAC control module connector.
Is resistance less than 1 M
7 1) Check resistance between "WHT/BLU" wire terminal and
body ground.
Is resistance more than 1 M
8 1) Check air flow control actuator referring to "Air Flow
Control Actuator Inspection in Section 7A".
Is air flow control actuator normal?
