Detected condition and possible cause
Detected condition |
Possible cause |
The operation voltage does not reach the stva. Ecm does not receive communication signal from the stva. Stva can not operate properly or its motor locked |

Wiring diagram
Troubleshooting
Caution when using the multi-circuit tester, do not strongly touch the terminal of the ecm coupler with a needle pointed tester probe to prevent terminal damage. |
Note after repairing the trouble, clear the dtc using sds tool. Refer to “use of sds diagnosis reset procedures” . |

Special tool (a): 09900–25008 (multi circuit tester set) Tester knob indication resistance (Ω) Stva continuity ∞Ω¶ (infinity) (terminal . Ground)
Special tool
Stva resistance approx. 6.5 Ω (terminal “a” – terminal “b”, terminal “c” – terminal “d”) |

Active control inspection
At this time, if an operation sound is heard from the stva, the function is normal.
Self-diagnostic procedures
Use of mode select switch
Note
do not disconnect the coupler from ecm,
battery cable from battery, ecm ground
wire from engine or main fuse before
confirming dtc (diagnostic trouble code)
stored in memory. Such disconnection
may erase memorized information in ec ...

Speed sensor inspection
Inspect the speed sensor in the following procedures:
remove the speed sensor. Refer to “speed sensor removal and
installation” .
Connect a 12 v battery (between b and b/w), 10 kù
resistor (between b/r and b) and multi-circuit tester
(tester (+) probe to b and tester ...
