W/Harness Inspection

Tuner/Amplifier
U1010 Low Voltage Detected - W/Harness Inspection

Terminal and Connector Inspection

1. Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damage of component.
2. Perform checking procedure as follows.
(1) Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
(2) Check terminal separation, damage of locking device and connecting condition between terminal and wiring.

NOTE :
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for checking connecting condition. (After checking, reconnect the pin at correct position)

3. Is the problem found?






Power Circuit Inspection

1. IG KEY "OFF".
2. Disconnect the Tuner & Amplifier connector.
3. IG KEY "ON".
4. Check the voltage between Memory voltage of Amplifier unit and GND of Body.

Specification : Battery voltage




5. Is the measured value within specification?
