H3 Check RF ABS Valve Operation

- Connect New Generation Star (NGS) Tester as in H2.

- Command pump motor to run for four seconds ("trigger" must be pressed twice since each input will run motor for two seconds). This will ensure the accumulators are empty.

- Apply moderate brake pedal effort and have an assistant check that the RH front wheel will not turn. If wheel turns, replace brake pressure control valve block.

- Trigger all valves to energize.

- Have assistant check RH front wheel immediately after pressing trigger. The New Generation Star Tester will only energize valves for two seconds per trigger input).

- Did RH front wheel turn freely (with a two foot lever arm such as a tire iron) while valves were energized?

YES -- Go to H4. H4 Check LR ABS Valve Operation

NO -- Verify no "ECU internal failure" or "valve circuit failure" codes are stored by running the "On-Demand Self Test". If no codes are received, replace brake pressure control valve block. Restore vehicle. Retest system.
