Repair Instructions

EGR Valve Inspection

S5JB0B1206006

• Check EGR valve for wear or damage.

CAUTION

!

 

Do not disassembly EGR valve.

 

1) Check resistance between following terminals of 

EGR valve in each pair. If resistance is out of 
specification, replace EGR valve.

EGR valve resistance

2) Check EGR valve operation as following procedure. 

If check result is not satisfied, replace EGR valve.
a) When connecting battery positive (+) terminal to 

terminal “1” and its negative (–) terminal to 
terminal “5”, confirm EGR valve operates fully 
open.

b) When disconnecting battery from EGR valve, 

confirm EGR valve operates fully close.

CAUTION

!

 

When replacing EGR valve, perform 
“Initialize EGR valve data” mode of SUZUKI 
scan tool referring to “EGR Valve Data 
Initialization”.
