1-Shorted Solenoid

DIAGNOSIS
- Faulty solenoid and wiring
- Faulty PCM (Power Steering Control Module)

SYMPTOM
- Steering wheel is too easy to turn (or does not become firm as vehicle speed increases).
- Warning tight illuminates





1. Check solenoid.
a. Turn ignition switch "OFF."
b. Disconnect connector (B17).





c. Measure resistance solenoid connector terminals using digital ohmmeter. Connector & Terminal Specified resistance: To (B17) No. 1 -No. 2/5-9 ohm.
2. Check harness between PCM and solenoid.
a. Disconnect PCM from connector.
b. Connect connector (B17).





c. Chock resistance and continuity between connector (R91) terminals. Connector & Terminal/Specified resistance:
- (R91) No. 9-No. 11/5-9 ohm
- (R91) No. 9-Body/1 M ohm, or more
3. Check harness between power supply and solenoid.
a. Turn ignition switch "OFF."
b. Disconnect connector (B17).





c. Measure voltage across connector (B17) and GND. Connector & Terminal/Specified voltage: (B17) No. 2-Body / 0 V.

NOTE: When battery voltage is produced, line between power supply harness and solenoid + terminal is shorted to set solenoid in "full assist" state.
