System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN
SYSTEM DIAGNOSIS TEST MODE A ), and check the No. 10 (7.5 A) and
No. 38 (30 A) fuses in the under-dash fuse/relay box.

3. Inspect the connector and socket terminals to be sure they are all making good

contact.

If the terminals are bent, loose or corroded, repair them as necessary and
recheck the system.

If the terminals look OK, go to step 4.

4. With the connectors still disconnected, make these input tests at the appropriate

connector.
