ring to DTC flow table of
“ENGINE DIAGNOSIS” in
Section 6.Go to Step 2.
2 1) Turn ignition switch OFF and disconnect
ECM or TCM couplers.
2) Measure resistance between terminal “G02-
16” and “C43-5” of disconnected harness
side coupler.
Is it about 0 Ω
?Go to Step 3.“BRN” wire open.
3 Measure resistance between terminal “C43-5”
of disconnected harness side coupler and body
ground.
Is it infinity?Go to Step 4.“BRN” wire shorted to
ground

AUTOMATIC TRANSMISSION (4 A/T) 7B-51
DTC P1709 (DTC NO.51) ENGINE COOLANT TEMPERATURE/BAROMETRIC PRESSURE
SIGNAL CIRCUIT
1. ECM 3. TCM coupler (viewed from harness side)
2. TCM 4. ECM coupler (viewed from harness side)
DTC DETECTING CONDITION
Engine coolant temperature/barometric pressure signal voltage too low although A/T fluid temperature is
normal operating temperature and engine rev. is standard.
Step Action Yes No
1 Check DTC referring to “ENGINE DIAGNOSIS”
in Section 6.
Is any DTC detected?Inspect and repair refer-
ring to DTC flow table in
Section 6.Go to Step 2.
2 1) Turn ignition switch OFF and disconnect
TCM and ECM couplers.
2) Measure resistance between terminal “C44-
18” of disconnected harness side TCM cou-
pler and body ground.
Is it infinity?Go to Step 3.“WHT/BLK” wire shorted
to ground.
3 1) Turn ignition switch OFF and connect TCM
couplers.
2) Turn ignition switch ON and check voltage
between terminal “C44-18” and body
ground.
Is it 0V?Substitute a known-good
TCM and recheck.Substitute a know-good
ECM and recheck.

7B-74 AUTOMATIC TRANSMISSION (4 A/T)
3) If selector lever is in “P” range, shift selector lever to other
than “P” range with releasing shift lock referring to “SHIFT
LOCK SOLENOID MANUAL RELEASE” in this section.
4) Install cable end (1) and cable casing cap (2) to key interlock
cam (3) and its bracket (4), then install cable (5) to selector
pad (6).
5) With selector lever set at “P” position, turn ignition key to
“ACC” position and then check for following conditions.
With knob button released, ignition key can be turned from
“ACC” position to “LOCK” position.
With knob button pressed, ignition key cannot be turned from
“ACC” position to “LOCK” position.
6) Install steering column referring to Section 3C.
7) Install steering column hole cover.
8) Install center console.
9) Connect negative cable at battery and enable air bag sys-
tem, referring to “ENABLING AIR BAG SYSTEM” in Section
10B (if equipped).

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
 Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
 Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
