General Information: Removal & Installation Mazda 5 I

INSTALLATION OF RADIO SYSTEM

1. If a radio system is installed improperly or if a high-powered type is used, the CIS and other systems may be affected. When the vehicle is to be equipped with a radio, observe the following precautions: Install the antenna at the farthest point from control modules. Install the antenna feeder as far as possible from the control module harnesses. Ensure that the antenna and feeder are properly adjusted. Do not install a high-powered radio system.

Scheme 2

1. Before disconnecting connectors or removing electrical parts, disconnect the negative battery cable.

Scheme 3

Scheme 4

1. To remove the wiring harness from the clip in the engine room, pry up the hook of the clip using a flathead screwdriver. CAUTION: Do not remove the harness protective tape. Otherwise, the wires could rub against the body, which could result in water penetration and electrical shorting.

Scheme 5

Scheme 6

1. When disconnecting connector, grasp the connectors, not the wires.
2. Connectors can be disconnected by pressing or pulling the lock lever as shown.

Scheme 7

1. When locking connectors, listen for a click indicating they are securely locked.

Scheme 8

Scheme 9

1. When a tester is used to inspect for continuity or measuring voltage, insert the tester probe from the wiring harness side.
2. Inspect the terminals of waterproof connectors from the connector side since they cannot be accessed from the wiring harness side. CAUTION: To prevent damage to the terminal, wrap a thin wire around the tester probe before inserting into terminal.

Scheme 10

1. Pull lightly on individual wires to verify that they are secured in the terminal.

Scheme 11

1. Use the appropriate tools to remove a terminal as shown. When installing a terminal, be sure to insert it until it locks securely.
2. Insert a thin piece of metal from the terminal side of the connector and with the terminal locking tab pressed down, pull the terminal out from the connector.

Scheme 12

1. Handle sensors, switches, and relays carefully. Do not drop them or strike them against other objects.

2. The first letter indicates the base color of the wire and the second the color of the stripe. WIRING COLOR CODES CODE COLOR CODE COLOR B Black O Orange BR Brown P Pink G Green R Red GY Gray V Violet L Blue W White LB Light Blue Y Yellow LG Light Green

Scheme 14

1. When replacing a fuse, be sure to replace it with one of the same capacity. If a fuse fails again, the circuit probably has a short and the wiring should be inspected.
2. Be sure the negative battery terminal is disconnected before replacing a main fuse.
3. When replacing a pullout fuse, use the fuse puller.
