Electrical Troubleshooting ('97 Model)
Troubleshooting Flowchart - Lock-up Control Solenoid Valve A
Possible Cause
. Disconnected lock-up controlsolenoid valve A/B assembly
. Short or open in lock-up controlsolenoid valve A wire. Faulty lock-up control solenoid
lf the Honda PGMTester is available:
NO
Wire side of female terminals
PCM CONNECTORS
. OBD ll Scan Tool indicates CodeP1753.. Self-diagnosis i@ indicatorlight blinks once.
Check and record the freeze datarn case it is needed later for prob-lem verification.
Perform the lock,up controlsolenoid valve A test using theHonda PGM Tester.
The solenoid is OK at this time.Verify that all connectors in thecircuil are making good contact,
Did the solenoid pass the test?
Check for a Short to Power:r. I urn rne tgntUon swttch ut-f.2. Disconnecr the A (32P) and B(2 5P) connectors from thePCM.3. Turn the ignition switch ON (ll).4. Measure the voltage betweenthe 85 and A9 or A22 terminals.
Repair short to power in the wirebetween the 85 terminal and thelock-up control solenoid valve A.
ls there voltage?
Measure Lock-up Control Sole-noid Valve A Resistance:1. Turn the ignition switch OFF.2. Measure the resistancebetween the 85 and A9 or A22
Check for loose terminal fit in thePCM connectors, ll necessary,substitule a known-good solenoidvalve assembly or PCM andrecheck,
ls the resistance 12 25 ()?
