DTC B1064 : Side Sensor (Driver Side) Circuit Short to Power Circuit or Open
DTC B1066 : Side Sensor (Passenger Side) Circuit Short to Power Circuit or Open
Special tool
(A) : 09932-76010
Step Action Yes No
1 1) With ignition switch OFF, remove center pil-
lar lower trim and side sill scuff, then discon-
nect side sensor connector “G68” or “G71”.
2) Disconnect SDM connector “G66”.
3) Check proper connection to applicable side
sensor at terminals in “G68” or “G71” con-
nector.
4) If OK, measure resistance with connected
special tool (A).
• DTC B1064: between “G68-1” and “G66-17”
terminals, and between “G68-2” and “G66-6”
terminals.
• DTC B1066: between “G71-1” and “G66-16”
terminals, and between “G71-2” and “G66-5”
terminals.
Is resistance 0 – 1
Ω
?
Got to Step 2. DTC B1064
Repair open in “GRN/
WHT” or “GRN/BLK” wire
circuit.
DTC B1066
Repair open in “GRN/
YEL” or “GRN/ORN” wire
circuit.
2 1) Measure voltage with connected special
tool (A).
• DTC B1064: between “G66-17” terminal and
body ground, and between “G66-6” terminal
and body ground.
• DTC B1066: between “G66-16” terminal and
body ground, and between “G66-5” terminal
and body ground.
With ignition switch ON, is voltage 0 – 1 V?
Substitute a known-good
side sensor and/or SDM
and recheck. DTC B1064 :
Repair short “GRN/WHT”
or “GRN/BLK” wire circuit
to power circuit.
DTC B1066 :
Repair short “GRN/YEL”
or “GRN/ORN” wire circuit
to power circuit.
