AUTOMATIC TRANSAXLE (M13 ENGINE) 7B1-69
Troubleshooting
Fig. for Step 4
Step Action Yes No
1Was “A/T System Check” performed? Go to Step 2. Go to “A/T System Check”
in this section.
2 Check Timing Solenoid Valve Circuit for IG
Short or Open.
1) Turn ignition switch ON and measure volt-
age between terminal “E13-14” of harness side
TCM connector and ground.
2) Is it 0 – 1 V?
Go to Step 3. “WHT/RED” circuit
shorted to power circuit or
open.
3 Check Timing Solenoid Valve Resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector
on transaxle.
3) Check for proper connection to solenoid
valve at “WHT/RED” circuit.
4) Check resistance of solenoid valve. See
Fig.
Resistance between terminal of transaxle
side valve body harness connector and
transaxle:
11 – 15
Ω
(at 20°C (68°F))
Is check result satisfactory?
Go to Step 4. Replace timing solenoid
valve or lead wire.
4 Check Timing Solenoid Valve Circuit for
Ground Short.
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Measure resistance between terminal
“E13-14” of disconnected harness side
TCM connector and ground.
Is it 11 – 15
Ω
(at 20°C (68°F))
Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection” in
Section 0A.
If OK, substitute a known-
good TCM and recheck.
“WHT/RED” circuit
shorted to ground.
1. Valve body harness connector on harness
2. Valve body harness connector on transaxle
3. Ground (Transaxle)
