6-102 ENGINE DIAGNOSIS
DTC P1717
INSPECTION
STEP
1 Was "ENGINE DIAG. FLOW TABLE" performed?
2 Check PNP signal ("D" range signal).
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition
switch OFF. See Fig. 1.
2) Turn ignition switch ON and check PNP signal
("P/N" or "D" range) on display when shifting
selector lever to each range.
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminal E22-14 of ECM
connector connected. See Fig. 2.
Is "D" range on display (Is 0 – 1 V indicated) no matter
which of "R", "D", "2" and "L" range positions selector
lever may be at? See Fig. 3.
3 Is "P/N" range on display (Is 10 – 14 V indicated)
when selector lever is at one of "R", "D", "2" and "L"
range positions only? See Fig. 3.
4 Check PNP signal circuit.
1) Turn ignition switch OFF.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminal
E13-8.
4) If OK, then check voltage at terminal E13-8 in TCM
connector disconnected, with ignition switch ON.
Is it 10 – 14 V? See Fig. 4

When not using SUZUKI scan tool:
YES
Go to Step 2.
Intermittent trouble or
faulty ECM. Check for
intermittent referring to
"Intermittent and poor
connection" in Section
0A.
Check transmission
range switch and
circuits referring to
section 7B.
"Y" circuit open, poor
E31-7 connection,
select cable maladjusted,
transmission range
sensor maladjusted or
transmission range
sensor malfunction.
If all above are OK,
substitute a
known-good TCM and
recheck.
