(p.287)
Continuity of the HARNESS ASSY CHUTE
1. Disconnect P/J24 on the HVPS/MCU.
(Refer to "Connectors (p.406)")
1
2. Check continuity of the following wiring:
J24-14 ↔ J245-5
J24-15 ↔ J245-4
♦ Does each wiring between J24 ↔ J245 have
continuity?
Continuity of the HARNESS ASSY TRAY1
1. Remove the CLUTCH REGI (p.173)
2. Disconnect the P/J245.

3
2.
♦
Is the coil resistance of the CLUTCH REGI
172Ω ± 10% (20°C)?
Continuity of the HVPS/MCU
1. Disconnect P/J24 and P/J10 on the HVPS/MCU.
4
