Scan Tool Testing and Procedures

(1) DTC CHART





Emergency mode 1
- Gear shifting is available by manual shift to each gear range.

(2) ADVICE
1. Symptom simulation test
Perform symptom simulation test on the basis of user's condition refer to below factor.
Factor for "occurring-road condition, speed, accelerate, reduce speed, straight, curve, time, weather and etc".
2. Inspect connection condition of between connectors
Inspect failure between connectors by visual check and contact pressure check.
"Connector disconnected", "Terminals rusted", "Terminals deformation or loose fit"
3. Inspect continuity of wire harness
- Disconnect both ends connector of wire harness, measure resistance between one connector terminal and other.
< OK > 1 ohm or less (No open circuit)
< NG > Infinity ohm (Open circuit)

NOTE:
1. Measure resistance while slightly shaking wire harness vertically and horizontally.
2. It is rare case wire harness is broken at the middle of it, and most cases occur at the connector.

4. Inspect short circuit of wire harness
- Disconnect connectors of wire harness at both ends, measure resistance between the applicable terminals of connector and body earth.
< OK > 1 M ohm or higher (No short circuit)
< NG > Low resistance (Short circuit)
- Measure resistance between one terminal and another terminal in the same connector. (Except between power supply or between earth)
< OK > 1 M ohm or higher (No short circuit)
< NG > Low resistance (Short circuit)

NOTE:
1. Measure wire harness while slightly shaking vertically and horizontally
2. It is usual case of short circuit that wire harness is crowded body and clamping failure.

5. Temporary connection failure of connector
It is thought that temporary connection failure of connector is cause when you can not decide cause of DTC detection.
