TROUBLESHOOTING CHART

Step	Action	YES	NO
1	Was "ABS Check" performed?	Go to Step 2.	Go to ABS CHECK .
2	Disconnect ABS (ESP®) hydraulic unit/control module connector with ignition switch turned OFF. Check for proper connection to ABS (ESP®) control module connector at terminals "E03 - 14" and "E03-13" (or "E53-1" and "E53-47"). If OK, then turn ignition switch to ON position and measure voltage between terminals "E03-14" and "E03-13" (or "E53-1" and "E53 - 47"). Is voltage 9.7 ± 0.3 V or more?	Go to Step 5.	Go to Step 3.
3	Turn ignition switch to OFF position. Check for proper connection to ABS (ESP®) control module connector at terminals "E03 - 13" and "E03-26" (or "E53-16" and "E53-47"). If OK then turn ignition switch to ON and measure resistance between each terminal of "E03-13", "E03-26" (or "E53-16", "E53-47") and vehicle body ground. Is resistance less than 2 Ω?	Go to Step 4.	"BLK" wire circuit in open or high resistance.
4	Measure voltage between positive battery terminal and vehicle body ground with engine running. Is voltage 9.7 ± 0.3 V or more?	Imperfect short between "WHT/RED" wire circuit and body ground.	Check charging system referring to GENERATOR TEST (UNDERCHARGED BATTERY CHECK) .
5	Measure voltage between terminals "E03-14" and "E03-13" (or "E53-1" and "E53-47") with engine running. Is voltage 18 ± 1.0 V or less?	Poor connection of "E03-14" and/or "E03-13" (or "E53-1" and/or "E53-47") terminals. If the terminals are in good condition, substitute a known-good ABS (ESP®) hydraulic unit/control module and recheck.	Check charging system referring to GENERATOR TEST (OVERCHARGED BATTERY CHECK) .
