EBS01054 6. Rear brake relay EBS01053 Remove the rear brake relay from the wire harness. Connect the pocket tester ( Ω Ч 1) and bat- tery (12 V) to the rear brake relay as shown. Positive battery terminal yellow/white 1 Negative battery terminal black 2 Positive tester probe black/yellow 3 Negative tester probe black 4 2 1 4 3 Does the rear brake relay have continuity between black/yellow and black? YES NO Replace the rear brake relay. Are the testing readings correct? YES NO Replace the diode 2. 9 - 20 ELECTRIC STARTING SYSTEM ELEC – + ELEC – + 7. Diode 2 • Remove the diode 2 from the wire har- ness. • Connect the pocket tester (Ω × 1) to the diode 2 as shown.
• Measure the diode 2 for continuity as fol- lows. NOTE: _T he pocket tester 90890-03112 and the ana- log pocket tester YU-03112-C readings are shown in the following table. Positive tester probe → black/yellow 1 Negative tester probe → sky blue 2 Continuity Positive tester probe → black/yellow 1 Negative tester probe → blue/black 3 Continuity Positive tester probe → sky blue 2 Negative tester probe → black/yellow 1 No continuity Positive tester probe → blue/black 3 Negative tester probe → black/yellow 1 No continuity 1 2 3 Sb L/B B/Y Y/W B/Y B B Sb L/B
