A. Deicer relay B. Not used C. HAC relay D. Blower relay E. B/Horn relay F. Not used G. Not used H. Start relay |
I. C/Fan (low) relay J. Rear defogger relay K. Horn relay L. Fuel pump relay M. C/Fan (hi) relay N. SSB relay (ACC) O. SSB relay (IG1) P. SSB relay (IG2) |
| 1. | There should be continuity between the No.30 and No.87 terminals when power and ground are connected to the No.85 and No.86 terminals. |
| 2. | There should be no continuity
between the No.30 and No.87 terminals when power is disconnected.
|
Check for continuity between the terminals.
A : Rain sensor relayB : Wiper relay
| 1. | There should be continuity between the No.30 and No.87 terminals when power and ground are connected to the No.85 and No.86 terminals. |
| 2. | There should be continuity between
the No.30 and No.87 terminals when power is disconnected.
|
Check for continuity between the terminals.
A : Main relay| 1. | There should be continuity between the No.30, 87a and No.87 terminals when power and ground are connected to the No.85 and No.86 terminals. |
| 2. | There should be no continuity
between the No.30, 87a and No.87 terminals when power is disconnected.
|
| 1. | Be sure there is no play in the fuse holders, and that the fuses are held securely. |
| 2. | Are the fuse capacities for each circuit correct? |
| 3. | Are there any blown fuses? If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew first and completely eliminate the problem before installing a new fuse. |
Multi Fuse is for optimizing the engine room package.

Function
Function RequirementsThe BCM controls IPS and relay on the SJB. For example,
if BCM requests head lamp low beam control, then BCM requests related lamp control
at one time.
