safe relay.
7CHECK MOTOR RELAY POWER SUPPLY
VOLTAGE.
1) Disconnect the connectors (B423) and
(VC1).
2) Turn the ignition switch to ON.
3) Measure the voltage between connector
(B423) and chassis ground.
Connector & terminal
(B423) No. 5 (+) — Chassis ground (–):
Is the voltage 10 — 15 V? Go to step 8.Repair the power
supply circuit.
