Circuit Inspection
| Item | Normal Value | Prerequisite Condition | Probe (+) | Probe (-) |
|---|---|---|---|---|
| Signal circuit (open): resistance | Approx. below 1Ω |
|
Encoder A terminal of SBW actuator | Encoder A terminal of SCU |
| Encoder B terminal of SBW actuator | Encoder B terminal of SCU | |||
| Signal circuit (short to battery): resistance | ∞ (Infinity) Ω |
|
Encoder A terminal of SBW actuator | Battery + terminal |
| Encoder B terminal of SBW actuator | Battery + terminal |
- Is the measured value within specifications?
YES
- Check a open or short circuit at the wiring of SBW actuator and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- If wiring of Inhibitor switch is normal then, substitute with a known-good SCU and check for proper operation.
If the problem is corrected, replace SCU and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known-good SBW actuator and check for proper operation. If the problem is corrected, replace SBW actuator and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
