Preliminary work: Diagnosis - Diagnostic Trouble Code (DTC) Memory 12

Fuses OK. Battery voltage 11-14 Volts (always connect battery charger when working on the soft top). RB control module must release soft top for operation (indicator lamp in RB switch should not blink). If soft top does not release, see DTC 23, in 12. In DTC memory, no DTC's (i.e.:19, 21, 24 - 30) which could prevent soft top operation can be stored, these must be cleared from memory. If a stored DTC cannot be cleared from memory, repair defect. Review entire 11.2 section before performing test. Note: Connect yellow wire from impulse counter scan tool to Socket 10 Model 129.06 (X11/4, 16-pole) Socket 21 Model 129.07 (X11/4, 38-pole) See Connection Diagram - Impulse Counter Scan Tool in section 0. CAUTION! Note regarding limit switch testing: 1. Ignition: OFF 2. Bridge sockets 1 and 3 of connector (X11/12) in passenger footwell ( 21, Figure 1). 3. Ignition: ON 4. Remove bridge. Electrical wiring diagrams: Electrical Troubleshooting Manual, Model 129. CAUTION! The test in the next section ( 23) calls for the connection of the socket box to the power soft top control module in 3 different ways. Connections are distinguished as connections made to the power soft top control module connector X, Y or Z. These are indicated in the test as follows: X indicates that the socket box should be connected according to Connection Diagram X ( 22, Figure 1) Y indicates that the socket box should be connected according to Connection Diagram Y ( 22, Figure 2) Z indicates that the socket box should be connected according to Connection Diagram Z ( 22, Figure 3) Note regarding connecting socket box to soft top control module: Ignition: OFF Disconnect connector (X, Y, Z) from control module. Connect socket box.
