Pinpoint Test

1. Ignition ON.
2. Using a scan tool, carry out the ABS module self-test.

Is DTC U3003:16 or U3003:17 present? 

1. Yes:

   For DTC U3003:16, REFER to Diagnostic Routine A: U3003:16 .

   For DTC U3003:17, REFER to Diagnostic Routine P: U3003:17 .

2. No: GO to 2  .

1. Ignition ON.
2. Measure and record the voltage at the battery.
3. Using a scan tool, monitor the VPWR_ABS PID.

Is the PID display within 0.2 volt of the recorded battery voltage? 

1. Yes: GO to  4  .
2. No: GO to 3  .

1. Ignition OFF.
2. Disconnect ABS Module electrical connector.
3. Ignition ON.
4. Measure:

   ABS Module			Ground
   C135			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   1	SBB05 (GY/RD)		-	Ground
   8	CBB92 (GN/WH)		-	Ground
   32	SBB43 (BU/RD)		-	Ground

Is each voltage within 0.2 volt of the recorded battery voltage? 

1. Yes: GO to 4  .
2. No: VERIFY BJB fuses 5 (50A), 43 (40A) and/or 92 (10A) are OK. See FUSE AND RELAY INFORMATION .

   If not OK, REFER to the appropriate OEM WIRING DIAGRAMS to identify the cause of the circuit short. If OK, REPAIR the affected circuit for high resistance or an open.

1. Ignition OFF.
2. Disconnect the battery negative cable. REFER to REMOVAL AND INSTALLATION - Battery Disconnect.
3. Measure:

   ABS Module			Ground
   C135			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   16	GD120 (BK/GN)		-	Ground

Is the resistance less than 3 ohms? 

1. Yes: GO to 5  .
2. No: REPAIR the circuit.

1. Inspect the ABS Module electrical connector (if not previously disconnected).
2. Repair:
   • corrosion (install new connector or terminal - clean module pins)
   • damaged or bent pins - install new terminals/pins
   • pushed-out pins - install new pins as necessary
3. Connect the ABS Module electrical connector. Make sure it seats and latches correctly.
4. Operate the system and determine if the concern is still present.

Is the concern still present? 

1. Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions.

   On vehicles not equipped with adaptive cruise control, if no TSBs  address this concern, INSTALL a new ABS module. REFER to Anti-Lock Brake System (ABS) Module .

   On vehicles equipped with adaptive cruise control, if no TSBs  address this concern, INSTALL a new ABS module and HCU. REFER to Anti-Lock Brake System (ABS) Module  and Hydraulic Control Unit (HCU) .

2. No: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
