Is DTC B1077 indicated? YES

-Check for loose or poor connections at the driver's MICU and the windshield wiper motor. If the connections are OK, substitute a known-good driver's MICU(driver's under-dash fuse/relay box), and recheck. If the DTC does not reappear, replace the driver's under-dash fuse/relay box, USA models (see page 22-86), Canada models (see page 22-87).

NO

-lntermittent failure, the system is OK at this time.

Check for loose or poor connections.

NO

-Replace the windshield wiper motor and recheck.

8. Reconnect the wiper motor 5P connector.

9. Measure the voltage between body ground and windshield wiper motor 5P connector terminal No. 3 with the wiper switch ON (Low), and measure the voltage between body ground and windshield wiper motor 5P connector terminal No. 5 with the wiper switch ON (High) individually.

Is there battery voltage? YES

-Go to step 10.

NO

-Test the windshield wiper relay circuit (see page 22-93). If the relay circuit is OK, check terminals F7 and F8 of driver's under-dash fuse/relay box connector F (33P) using the input test (see page 22-315). If the input tests prove OK, replace the driver's under-dash fuse/relay box (see page 22-86). If the relay circuit is faulty, replace the left engine compartment wire harness, USA models (see page 22-86), Canada models (see page 22-87).

10. Measure the voltage between body ground and windshield wiper motor 5P connectorterminal No. 2 [No. 4] .
