A7 Check Continuity of Circuit 8 (W/P) and 91 (BK/Y)

- Turn ignition switch to the OFF position.

- Connect Rotunda 60-Pin Breakout Box 007-00033 with Rotunda ABS Breakout Box Adapter 007-00115 or equivalents to the anti-lock brake control module.

- Using Rotunda 73 Digital Multimeter 105-R0051 or equivalent set to ohms, measure resistance of circuit 8 (W/P) from pin 15 at breakout box to pin 1 at data link connector.

- Measure resistance of circuit 91 from pin 5 at breakout box to pin 2 at data link connector.

- Measure resistance of circuit 91 from pin 5 to a known good ground.

- Is resistance 5 ohms or less?

YES -- Go to A8. A8 Check Circuit 8 (W/P) For Short to Ground

NO -- Service circuits 8 (W/P) or 91 (BK/Y) for open circuit. Restore vehicle. Retest system.
