INSPECTION
Step
1
Was "ENGINE DIAG. FLOW TABLE" per-
formed?
2
Is SUZUKI scan tool available?
3
Check PNP Signal ("D" range signal).
1) Connect SUZUKI scan tool to DLC with igni-
tion switch OFF. See Fig. 1.
2) Turn ignition switch ON and check PNP sig-
nal ("P/N" or "D" range) on display when
shifting selector lever to each range.
Is "D" range on display (Is 0 – 1 V indicated) no
matter which of "R", "D", "2" and "L" range posi-
tions selector lever may be at? See Table 1.
4
Check PNP Signal ("D" range signal).
1) Turn ignition switch ON.
2) Check voltage at terminal C41-14 (Case of
TYPE A. See NOTE) or G02-6 (Case of
TYPE B. See NOTE) 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 posi-
tions selector lever may be at? See Table 1.
5
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?
6
Check PNP Signal Circuit.
1) Turn ignition switch OFF.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at ter-
minal C44-8.
4) If OK, then check voltage at terminal
C44-8 in TCM connector disconnected, with
ignition switch ON.
Is it 10 – 14 V? See Fig. 3

Yes
Go to Step 2.
Go to Step 3.
Intermittent trouble or
faulty ECM. Check for
intermittent referring to
"Intermittent and poor
connection" in Section 0A.
Intermittent trouble or
faulty ECM. Check for
intermittent referring to
"Intermittent and poor
connection" in Section 0A.
Check transmission range
switch and circuits refer-
ring to section 7B.
"GRN/ORN" circuit open,
poor transmission range
switch connector connec-
tion, select cable malad-
justed, transmission
range sensor malad-
justed or transmission
range sensor malfunction.
If all above are OK, sub-
stitute a known-good
TCM and recheck.
No
Go to "ENGINE DIAG.
FLOW TABLE".
Go to Step 4.
Go to Step 5.
Go to Step 5.
Go to Step 6.
"LT BLU" (Case of TYPE
A. See NOTE) or "GRN
RED" (Case of TYPE B.
See NOTE) circuit open or
poor C41-14 (Case of
TYPE A. See NOTE) or
G02-6 (Case of TYPE B.
See NOTE) connection.
If wire and connection are
OK, substitute a known-
good ECM and recheck.
