Condition Some customers may comment on ABS activation at low speeds, usually below 8 km/h (5 mph). Upon investigation, the technician will find no DTCs set. Cause The cause of this condition may be an increased air gap between the wheel speed sensor and the hub reluctor ring due to rust and debris built up on the sensor mounting surface. Correction Measure AC voltage and clean the wheel speed sensor mounting surfaces. 1. 2. 3. 4. Raise and support the vehicle. Disconnect both the front wheel speed sensor connectors at the frame and harness. Place a Digital Volt Meter (DVM) across the terminals of each wheel speed sensor connector. Rotate the wheel clockwise approximately one revolution per second. The minimum reading should be at least 350 ACmV’s. If the reading is less than 350 ACmV’s, remove the wheel speed sensor. 5. Plug the wheel speed sensor bore in order to prevent debris from falling into the hub during service. 6. Clean the wheel speed sensor mounting surface using a wire brush, sand paper, emery cloth, scotch brite, or other suitable material. Be sure to thoroughly clean the wheel speed sensor surface. There should be no rust or corrosion. 7. Check the sensor head to determine if it has been warped/distorted due to the corrosion build up or other causes. Check the mounting surface on the sensor head for flatness by placing it on the edge of a metal machinists scale or other suitable straight edge to measure the flatness. Check the sensor for flatness in multiple (minimum 3) positions/directions. If the sensor head is distorted, replace the sensor. 8. Apply (spray) two thin coats of the specified rust penetrating lubricant (corrosion inhibitor) to the complete sensor mounting surface on the bearing hub. Allow to dry for 3-5 minutes between coats. Use ONLY Rust Penetrating Lubricant, P/N 89022217 (in Canada, P/N 89022218). 9. When the corrosion inhibitor is dry to the touch (about 10 minutes), apply a thin layer of bearing grease to the hub surface and sensor O-ring prior to sensor installation. Use ONLY Wheel Bearing Lubricant, P/N 01051344 (in Canada, P/N 993037). 10.Install either the original sensor or a new one in the hub. Ensure that the sensor is seated flush against the hub. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual. 11.Place the DVM across the sensor terminals and recheck the voltage while rotating the wheel. The voltage should now read at least 350 ACmV’s.

#PIP4015: SES Light Due To DTCs P0105 P0106 And/Or P0506 – Clean Throttle Body – keywords body clean code codes deceleration DTC engine erratic idle intermittent low PCM plate surge unstable 2004-2007 Buick Rainier 2002-2007 Chevrolet TrailBlazer 2004-2007 Chevrolet Colorado 2002-2007 GMC Envoy 2004-2007 GMC Canyon 2002-2004 Oldsmobile Bravada 2006-2007 HUMMER H3 2005-2007 Saab 9-7X Condition/Concern: On rare occasions, a SES light may be experienced due to DTCs P0105, P0106, and/or P0506. There may or may not be an idle complaint accompanying the SES light. This may be due to excessive carbon build up in the throttle body. Recommendation/Instructions: If the SI diagnostics do not isolate a cause for this concern, clean the throttle body bore and plate for evaluation.

1. Connects via USB to PC
2. Immo1 & Immo2 supported up to year 2004
3. Read Login code
4. Programm new keys
5. Read and erase error codes of IMMO
Reading of PIN for immo1 works only if pin code already have been entered sometimes before
Reading of PIN code for immo2 is not possible by OBD

1. Turn ignition on, with engine off. Using scan tool, read ECT sensor voltage. If voltage is less than .5 volt, go to next step. If voltage is .5 volt or more, go to step 6). 2. Turn ignition off. Disconnect ECT sensor connector. See Fig. 24 . Clean and/or repair connector as necessary. Turn ignition on, with engine off. Using scan tool, read ECT sensor voltage. If voltage is more than 4 volts, replace ECT sensor. Perform TEST VER-5A. If voltage is 4 volts or less, go to next step. 3. Turn ignition off. Ensure ECT sensor connector is still disconnected. Disconnect PCM connectors. PCM is located in engine compartment. See PCM LOCATION table under SYSTEM DIAGNOSTICS. Clean and/or repair connectors as necessary. Using an ohmmeter, check resistance between ground and ECT sensor connector, signal circuit (Tan/Black wire). If resistance is less than 5 ohms, repair short to ground in signal circuit. Perform TEST VER-5A. If resistance is 5 ohms or more, go to next step. 4. Ensure ignition is off. Ensure ECT sensor and PCM connectors are still disconnected. Using ohmmeter, check resistance between ECT sensor connector, signal circuit (Tan/Black wire) and sensor ground circuit (Brown/Yellow wire). If resistance is less than 5 ohms, repair signal circuit for short to sensor ground circuit. Perform TEST VER-5A. If resistance is 5 ohms or more, go to next step. 5. At this time, PCM is assumed to be defective. Replace PCM. Perform TEST VER-5A. 6. Turn ignition on, with engine off. Wiggle ECT sensor connector and wiring harness while monitoring ECT sensor voltage. See Fig. 24 . If voltage changes while wiggling connector and wiring harness, repair connector or wiring harness where wiggling caused voltage to change. Perform TEST VER-5A. If voltage does not change, go to next step. 7. Turn ignition off. Visually inspect related connectors and wiring harness for damage. Repair connectors and wiring harness as necessary. Perform TEST VER-5A. If connectors and wiring harness are okay, test is complete.

WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer’s specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury. WARNING: Carefully read cautionary information on product label. For EMERGENCY MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft products call: 1-800-959-3673. For additional information, consult the product Material Safety Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal injury. WARNING: Always install new brake shoes or pads at both ends of an axle to reduce the possibility of brakes pulling vehicle to one side. Failure to follow this instruction may result in uneven braking and serious personal injury. NOTICE: Do not spill brake fluid onto painted or plastic surfaces or damage to surface may occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface with water. 1. Check the brake fluid level in the brake master cylinder reservoir. If required, remove the fluid until the brake master cylinder reservoir is half full. 2. Remove the wheel and tire. For additional information, refer to Section 204-04. 3. NOTICE: Do not allow the brake caliper to hang by the flexible brake hose or damage to the hose may occur. Remove the 2 brake caliper guide pin caps and bolts and position the caliper and brake pad assembly aside. Support the caliper using mechanic’s wire. Remove and discard the guide pin bushings. Inspect the guide pin threads for damage, install new guide pin(s) as necessary. 4. Remove the brake pads from the caliper. 5. Inspect the brake pads for wear or contamination and install new pads as necessary. For additional information, refer to General Procedures in Section 206-00. 6. Using a C-clamp and a worn brake pad, press the piston into the caliper. 7. Inspect the brake disc and resurface or install a new brake disc as necessary. For additional information, refer to General Procedures in Section 206-00. Installation 1. Clean, dry and inspect the brake caliper anchor plate. Apply equal amounts of the supplied yellow lubricant to the 4 brake pad contact points on the anchor plate as shown. 2. NOTICE: Do not apply lubricant to guide pin threads or incorrect tightening of the guide pins may result. Install new brake hardware as follows: Apply equal amounts of the supplied white lubricant to the inside of the guide pin bushings. Install the guide pin bushings into the caliper bores. Install the guide pins into the bushings. 3. Install the brake pads to the caliper. 4. Position the caliper onto the anchor plate and install the 2 brake caliper guide pin bolts. To install, tighten to 38 Nm (28 lb-ft). Clean and dry guide pin threads as necessary. 5. Fill the master cylinder with clean, specified brake fluid. 6. Install the wheel and tire. For additional information, refer to Section 204-04. 7. Apply the brake several times to verify correct brake operation.
