Condition The anti-theft alarm (ATA) may sound for no apparent reason after being armed DTC P1716, indicating an interior protection/tow sensor fault may be stored in the All Activity Module (AAM) as a result. The possible cause of this condition may be a software error in the security/trip computer tow sensor. Procedure 1. Verify that this service campaign has not already been performed (see step 5) 2. Replace the security/trip computer depending on the vehicle options (see WIS: AR54.21-P-9832GH Removing and installing trip computer control module and AR82.20-P-1100GH, Removing and installing front overhead control panel). 3. Version code the AMM using StarDiagnosis (DAS) or the Hand-Held Tester (HHT) as follows: ^ 09 Trip computer ^ Set to “present” (if equipped) ^ 12 ATA Interior/anti-tow protection ^ Set to present 4. Read out and erase any relevant DTC’s using StarDiagnosis or the HHT. 5. Affix the orange sticker supplied with the replacement computer to the inside of the garage door opener access panel or Home-link(R) universal access panel. Note: The orange sticker is used to identify the vehicle as having been retrofitted with a new security/trip or security computer. Do not confuse the aforementioned orange sticker with the orange or green sticker that may already be present on the replacement security/trip computers.

CAUTION: See brake fluid notes See notes on repairs to brake system 1 Check fluid level The fluid level must be between the “MAX.” and “MIN.” marks embossed in the brake fluid expansion reservoir (10). 2 If fluid level is too low, locate and rectify the cause Check brake disks and brake pads for wear and condition. Check brake system, ABS, ETS, ASR, ESP, SBC (also pressure reservoir, charging pump and charge plunger unit in wheelhouse) for leak tightness.

Vehicles with ETS, ESP or ASR have wear sensors for the brake pad wear indicator on the rear axle. There are the following versions: No sensor 2 sensors 4 sensors There are the following versions on the front axle: 2 sensors 4 sensors. When replacing brake pads only install as many sensors as were fitted originally. if only one wear sensor is fitted to a wheel, it is to be fitted to the outer brake pad. Wear sensors which are not connected result in the brake pad wear malfunction indicator lamp coming on due to moisture. NOTE The wear sensor cable must be routed as shown in the illustration. Only the transparent (temperature-resistant) version of the wear sensors may be installed on the rear axle.

The hydraulic pressure from the dual master cylinder is split diagonally between the right front/left rear and left front/right rear wheel brake circuits, providing a balanced braking response should a malfunction occur in a brake line. The proportioning valve function is produced by the Electronic Brake Proportioning System (EBP). EBP dynamically adjusts the application of hydraulic pressure to the rear brakes. Both front and rear brakes are disc type with single piston floating calipers. The front discs are internally ventilated while the rear discs are solid. To ensure better ventilation of the brakes, additional openings for cooling air have been integrated into the bumper. The parking brakes are drum type with the drum located in the hub area of the rear disc. The self adjusting brake mechanism is like the W140 and is located under the passenger compartment second seat row. Component Location 4-ETS/ABS Hydraulic Unit
