Step
2 Check shift solenoid valve circuit for IG short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at termi-
nal "E13-16" (for shift solenoid valve-A (No.1))
or "E13-15" (for shift solenoid valve-B (No.2)).
4) If connection is OK, turn ignition switch ON and
measure voltage between terminal "E13-16"
(for shift solenoid valve-A (No.1)) or "E13-15"
(for shift solenoid valve-B (No.2)) of discon-
nected harness side TCM connector and
ground.
Is it 0 – 2 V?
3 Check shift solenoid valve resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector on
automatic transmission.
3) Check for proper connection to solenoid at
"BRN" (for shift solenoid valve-A (No.1)) or
"BLK/YEL" (for shift solenoid valve-B (No.2))
circuit.
Check resistance of solenoid valve. See Fig.
Resistance between shift solenoid valve-A
(No.1) terminal and transaxle: 11 – 15
20°C? (68°F)
Resistance between shift solenoid valve-B
(No.2) terminal and transaxle: 11 – 15
20°C? (68°F)
Is check results satisfactory?

Go to Step 3.
Intermittent trouble or
faulty TCM. Check for
intermittent referring to
"Intermittent and Poor
Connection" in Sec-
tion 0A. If OK, substi-
tute a known-good
TCM and recheck.
