Switch Test E.7.7 - Cruise Resume/ACCEL Switch

After .7.0 is displayed on FDC, PCM switch test can be initiated by depressing brake pedal. When brake pedal has been depressed, FDC will display E.7.0. At this time the HI and LO buttons on ECC panel can be used to select specific switch test.

When a specific test has been selected and that switch activated, display will alternately display code for that test and E.0.0 to confirm that switch is working.

This test detects closing of RESUME/ACCEL switch at PCM terminal C3. Ensure cruise control switch is in ON position when performing this test. Switch Test E.7.5 should be performed before this test, to ensure power to RESUME/ACCEL switch.
