ABS INDICATOR LAMP ON STEADY/ INTERMITT. & CODE 57,62, OR 65. Saturn Saturn 1994

For 1990-2009 cars

# ABS INDICATOR LAMP ON STEADY/ INTERMITT. & CODE 57,62, OR 65

#### SUBJECT: ANTI - LOCK Brake Indicator Lamp on Steady or Intermittently and Code 57, 62 or 65 is Retained in Electronic Brake Control Module Memory (Repair Wiring Harness)

#### MODELS AFFECTED: 1994 Saturns equipped with anti - lock brakes

CONDITION: The ANTI - LOCK brake indicator lamp may be On at all times or On intermittently. When performing a diagnostic check, ABS code 57, 62 or 65 is stored in memory.

CAUSE: The ABS wiring harness from the electronic brake control module assembly is routed near a weld-stud on the body frame and may become pinched, causing wires in the ABS wiring harness to short - to - ground.

CORRECTION: Inspect ABS wiring harness and repair if necessary according to procedure in this bulletin. If determined during inspection that the ABS wiring harness has not contacted the weld-stud and shorted-to-ground, refer to the "Brakes Service Manual" for further diagnostic procedures.

PROCEDURES

1. Disconnect negative battery terminal.

2. Turn the powertrain control module (PCM) retaining screw, with a screwdriver, 1/4 turn counterclockwise and remove from bracket.

3. Disconnect wiring harness connectors.

4. Turn the electronic brake control module assembly retaining screw, with a screwdriver, 1/4 turn counterclockwise and remove from bracket.

5. Disconnect wiring harness connectors.

6. Remove three bolts from electronic brake control module and PCM bracket and remove from vehicle.

7. Using a side cutter, cut rosebud type retainers that hold the ABS control module wiring harness on to the electronic brake control module and PCM bracket assembly.

8. Gently pull ABS control module wiring harness down from behind the electronic brake control module and PCM bracket assembly.

9. Carefully inspect wires for any slight crease, indentation or chafing in location indicated in illustration.

#### IMPORTANT: Remove tape as necessary from harness to thoroughly inspect wires by bending them in various directions. What may appear to be a very slight crease or indentation on the wires is enough to have caused the condition when pressed hard up against the weld - stud on the body frame.

10. If wires show signs of a crease or indentation, repair by applying electrical tape to affected wires and taping ABS control module wiring harness in affected area, then proceed to step 12.

11. If wires show evidence of chafing and wire strands on wire (or wires) have been damaged, replace damaged section of wire (or wires) according to procedures in the "Electrical Troubleshooting" section of the "Electrical Service Manual." After wire repair, tape ABS control module wiring harness in affected area and proceed to next step.

12. Position ABS control module wiring harness behind electronic brake control module and PCM bracket assembly, below weld-stud location, so that wire damage cannot occur.

#### IMPORTANT: It is not necessary to replace the rosebud type retainers since the primary purpose was to aid in vehicle manufacturing. The electronic brake control module and PCM bracket assembly, when installed, will hold the ABS control module wiring harness in place.

13. Install electronic brake control module and PCM bracket with three bolts.

Torque: 10 N,m (89 in-lbs)

14. Connect electronic brake control module assembly connectors, and install electronic brake control module assembly into electronic brake control module and PCM bracket assembly by pushing into the bracket until two clicks are heard.

15. Connect PCM connectors, and install PCM into electronic brake control module and PCM bracket assembly by pushing into the bracket until two clicks are heard.

16. Connect negative battery terminal and reset clock.

Torque: 17 N,m (151 in-lbs)

17. Using portable diagnostic tool (PDT) or service stall system (SSS), clear ABS diagnostic codes.

18. Cycle ignition key to the LOCK position and then to the RUN position and verify that code 57, 62 or 65 does not reset. If code resets, refer to the "Brakes Service Manual" for further diagnostic procedures.
