Step
2 1) Check if communication is possible by trying communi-
cation with other control module (ECM or ABS control
module (if equipped)).
Is it possible to communicate with other control module?
3 1) With ignition switch ON, check voltage between DLC
terminal "G09-16" ("WHT/BLU" wire) terminal and body
ground.
Is voltage 10 – 14 V?
4 1) Check resistance the following serial data ground cir-
cuits.
• Between DLC terminal "G09-4" ("BLK" wire) terminal
and body ground.
• Between DLC terminal "G09-5" ("BRN" wire) terminal
and body ground.
Are resistances 0 – 1 Ω respectively?
5 1) With ignition switch OFF, disconnect SDM connector
"G66".
2) Check proper connection at "G66-28" ("WHT/RED"
wire) of SDM connector "G66".
3) If OK, then check resistance between "G66-28" ("WHT/
RED") of SDM connector "G66" and "G09-7" ("WHT/
RED") of DLC "G09".
Is resistance 0 – 1 Ω?
Action Yes
Go to step 3. Repair open in common
section of serial data circuit
("WHT/RED" wire circuit)
used by all controllers or
short to ground or power
circuit which has occurred
some-where in serial data
circuit ("WHT/RED" wire
circuit).
Go to step 4. Repair open in serial data
power circuit ("BLU/WHT"
wire circuit).
Go to step 5. Repair open in serial data
ground circuit ("BLK" or
"BRN" wire circuit).
Substitute a Repair high resistance or
known-good open in "WHT/RED" wire
SDM and circuit (between SDM con-
recheck. nector terminal "G66-28"
and DLC).
No
