DTC 32: Pump Motor Failure

  1. Turn ignition off. Disconnect coil integrated module harness connector. Measure voltage between ground and coil integrated module harness connector terminal No. 1 (White/Green wire). If battery voltage is present, go to next step. If battery voltage is not present, check condition of ABS fuse (60-amp) located in engine compartment fuse block. Check White/Green wire between fuse and coil integrated module for open or short to ground. Repair as necessary. After repairs, go to step  5.
  2. Ensure harness from Electronic Hydraulic Control Unit (EHCU) unit is connected to coil integrated module connector. Go to next step.
  3. Check condition of harness from EHCU. If harness is okay, go to next step. If harness is not okay, repair as necessary. After repairs, go to step  5.
  4. Measure resistance between EHCU connector pins No. 1 and 2 (component side). If resistance is .2-1.0 ohm, replace coil integrated module. If resistance is not .2-1.0 ohm, replace EHCU.
  5. Reconnect all components. Ensure all component are properly installed. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. Verify system operation. See SYSTEM OPERATION CHECK  under TROUBLE SHOOTING.
