NOTE: Diagnostic Trouble Code (DTC) Recognition 1. ABS control unit recognizes system related problems and causes ABS warning light to come on and stay on under any of following conditions: Vehicle is driven with parking brake on longer than 30 seconds. One rear wheel is locked. Wheel speed sensor does not transmit a signal. Vehicle is driven on extremely rough road. Low battery voltage. Operation time of solenoid valves exceeds a specified value and control unit indicates an open circuit in solenoid circuit. Output signals from control unit are not transmitted to solenoid valves. Temporary loss of traction due to excessive cornering speed or starting from stuck condition (mud, snow or sand). 2. If ABS warning light comes on intermittently, use ABS Tester (07HAJ-SG0010B) to confirm problem. See ABS FUNCTION TEST under DIAGNOSIS & TESTING. 3. ABS warning light comes on and trouble code is stored in control unit when insufficient battery voltage exists at control unit. If low battery voltage caused problem, recharge battery and clear trouble code(s). See CLEARING DTCs under SELF-DIAGNOSTICS. ABS Warning Light Does Not Come On If ABS warning light does not come on when ignition is on: Check bulb. Check Yellow wire between fuse No. 1 and instrument cluster. Check Blue/White wire between instrument cluster and control unit. Check control unit ground circuit. ABS Warning Light Stays On Without DTCs If ABS warning light stays on and no DTCs have been stored in control unit, check for following items: Loose or poor control unit connector. Blown ABS fuse No. B2 in underhood fuse/relay box. Open circuit in White/Black wire between ABS fuse No. B2 and control unit. Open circuit in Yellow/Black wire between fuse No. 7 and fail-safe relays. ABS system is okay if ABS warning light goes out after engine is started.

The fuse box is located under the dashboard to the left of the steering column. The underhood fuse panel (if equipped) is located beside the battery. The circuits protected by each fuse are listed on the plastic sheet inside the cover.

The Malfunction Indicator Light (MIL) may illuminate and DTC P0400 or P1195 may be stored in memory. This concern may be caused by any one of the following conditions: Mis-routed, twisted or kinked vacuum lines Swapped Pressure Regulator Control (PRC) and EGR Boost Sensor solenoid connectors. Defective EGR Boost Sensor PCM MIL misjudgment (1996 model with MTX) Customers complaining of this concern should have the vehicle inspected according to this bulletin and if necessary, repair. REPAIR PROCEDURE 1. Verify that all vacuum lines are properly routed, not kinked or twisted. 2. Locate the PRC and EGR boost sensor solenoid valves on the right side of the intake manifold. Refer to F1-3 (MTX) or F3-3 (ATX) of the 1996 workshop manual for solenoid location. Figure 1 3. Verify correct connector placement at the PRC and EGR Boost Sensor solenoid. If the connectors are not in the proper position, correct their placement and proceed to step 9. If the connectors are in the proper position, proceed to step 4. NOTE: The color of each connector varies with each powertrain. The PRC connector is the top connector and is BLACK or WHITE. The EGR boost sensor solenoid connector is the bottom connector and is ORANGE. 4. Inspect the EGR boost sensor. Warm engine to normal operating temperature. Measure the voltage between the signal wires (refer to table below) from the rear side of the connector.

NOTE : The vacuum hoses cannot be removed individually. Vacuum Control Solenoid – (Solenoid Valves) : The solenoid valves open and close the vacuum lines from the vacuum bells used to control the shutters, in response to electrical signals from the microprocessor. The few vacuum hoses which are installed are securely clamped, eliminating the risks of interchanging and pinching the hoses Heater Replacement Note: This procedure shows the 940 model. The 960, S90 and V90 models are similar. Disconnect battery ground lead. The following operation applies only to replacement of the heater:

The standard equipment for model 129 includes a hydraulically actuated roadster top and a coupe roof. The switch for opening and closing the top is located on the center console. The top can be opened within approx. 30 seconds and stored in the top compartment by pressing the switch toward the rear and holding in this position or removed from the top compartment and closed by pressing the switch toward the front and holding in this position (when closing it may be necessary to “help” slightly by manually guiding the front top frame into the initial catch on the front top locks). For this purpose roll down side windows and put down roll bar and return to initial position afterward. The top moves only as long as the switch is actuated. The motion can be interrupted at any desired point and then continued or reversed. During an interruption the top is locked hydraulically so that it cannot fall down. The lock is released when the ignition is switched off and the top can be moved freely. Five opening/closing operations are possible immediately one after another. More than five operations are not possible due to the thermic load on the pump and solenoid valves. Monitoring is accomplished by counting the switch-on time for the pump and solenoid valves. Prerequisites for actuating top ignition switched on vehicle standing still battery voltage > 10 V roll bar control unit must release top actuation no malfunctions prohibiting top actuation stored in malfunction memory limit switch signals from control unit recognized as logical the maximum operating time must not be exceeded removal of the coupe roof is possible only when the time after switching on the ignition is < 10 seconds NOTE: Do not touch top linkage, upper part of windshield or top compartment
