Unlock Position Sensor Signal Circuit: Procedure
- INSPECT STEERING LOCK ECU
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition (Steering Lock Position) Specified Condition E26-4 (SLP1) - E26-2 (SGND) Locked 11 to 14 V E26-4 (SLP1) - E26-2 (SGND) Unlocked Below 1 V
NG → See step 2
OK → See step 3
- Measure the voltage according to the value(s) in the table below.
- CHECK HARNESS AND CONNECTOR (STEERING LOCK ECU - MAIN BODY ECU)
- Disconnect the E26 steering lock ECU connector.
- Disconnect the E1 main body ECU connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E26-4 (SLP1) - E1-18 (SLP) Always Below 1 Ω E26-4 (SLP1) or E1-18 (SLP) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 4
- GO TO SMART ACCESS SYSTEM WITH PUSH-BUTTON START (FOR START FUNCTION) (HOW TO PROCEED WITH TROUBLESHOOTING). Refer to HOW TO PROCEED WITH TROUBLESHOOTING [01/2012 - ]
- REPLACE STEERING LOCK ACTUATOR (STEERING LOCK ECU). Refer to DISASSEMBLY [01/2012 - ]
