Power Mirror System Chevrolet Corvette C5

Mirrors 3 illustrations ~6187 words

DESCRIPTION

One mirror control switch adjusts both left (driver's side) and right (passenger's side) mirrors. Press left side of mirror select switch for driver's mirror or press right side of switch for passenger's mirror. Press arrows on switch pad to adjust mirror. Vehicle is equipped with heated and memory mirrors.

Each power mirror assembly contains 2 reversible motors: an up/down motor and a left/right motor. Mirror control switch reverses polarity of motor circuit to change direction of mirror movement. Each motor contains a self-resetting circuit breaker, which opens when mirror reaches its mechanical limit of travel. Each power mirror assembly contains potentiometers that are used to determine mirror position.

PROGRAMMING

On hardtop models, when a Door Control Module (DCM) is replaced, the DCM must be reprogrammed. Using scan tool, select RH DCM for right DCM or LH DCM for left DCM. Select DCM REPROGRAM and follow scan tool instructions.

PRELIMINARY INSPECTION

Check for broken or partially broken wire inside insulation, which could cause system malfunction, but prove good in a continuity/voltage check with system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring voltage drop with system operational (under load). Check power mirror system related fuses. Check and ensure grounds are clean and tight. See WIRING DIAGRAMS . Check for proper installation of aftermarket electronic equipment. Correct any obvious problems before continuing testing. If problem still exists, perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.

SYSTEM OPERATION CHECK

  1. Move mirror select switch to left mirror position. Operate left mirror to left, right, up and down positions. Mirror should operate as commanded in all positions.
  2. Move mirror select switch to right mirror position. Operate right mirror to left, right, up and down positions. Mirror should operate as commanded in all positions.
  3. To check memory mirror function, press memory No. 1 button. A single beep should be heard, and both mirrors should move to positions programmed for memory No. 1 button.
  4. Press memory No. 2 button. A single beep should be heard, and both mirrors should move to positions programmed for memory No. 2 button.
  5. If mirror system does not function properly, repair by symptom. See «SYMPTOM INDEX»(/chevrolet/corvette/c5-1997-2004/remont/mirrors/#power-mirror-system) table under SYMPTOM TESTS.

SELF-DIAGNOSTIC SYSTEM

Note. Diagnostic Trouble Code (DTC) tests are written specifically for use with GM Tech 1 or 2 scan tools. Generic scan tool can be used, but may have limited functions.

DTCs may be retrieved and cleared by using a scan tool or by using the Driver Information Center (DIC) located on Instrument Panel Cluster (IPC). When using the DIC to retrieve DTCs, if a DTC exists display will indicate whether DTC is current (with a "C") or history (with an "H"). When E/M button (switch 5) on DIC is pressed at any time, IPC will exit diagnostics mode. On-board diagnostics will also be exited automatically if no DIC buttons are pressed for longer than 60 seconds.

Note. For more information on Driver Information Center (DIC), see ANALOG INSTRUMENT PANELS - CORVETTE article.

Using Scan Tool

Note. If scan tool is not available, see USING ON-BOARD DIAGNOSTICS .

  1. Install scan tool. If scan tool powers up, go to next step. If scan tool does not power up, perform appropriate diagnostic procedure. See SELF-DIAGNOSTIC SYSTEM in appropriate BODY CONTROL MODULES article.
  2. Turn ignition on, engine off. Following scan tool manufacturer's instructions, attempt to establish communication with Left Driver Control Module (LDCM) and Right Door Control Module (RDCM). If communication with LDCM and RDCM is established, go to next step. If communication with LDCM and RDCM is not established, diagnose communication problem with class 2 device. See SELF-DIAGNOSTIC SYSTEM in appropriate BODY CONTROL MODULES article.
  3. Select display DTC function for LDCM and RDCM. Record all displayed DTCs, status of displayed DTCs and module that set the DTC. If DTCs are displayed, perform appropriate test. See «DIAGNOSTIC TROUBLE CODE INDEX»(/chevrolet/corvette/c5-1997-2004/remont/mirrors/#power-mirror-system) table. If no DTCs are displayed, perform system operation check. See «SYSTEM OPERATION CHECK»(/chevrolet/corvette/c5-1997-2004/remont/mirrors/#power-mirror-system__system-operation-check) under TROUBLE SHOOTING.

DIAGNOSTIC TROUBLE CODE INDEX

Using On-Board Diagnostics

Turn ignition on, engine off. Press RESET button to acknowledge any warning messages that may be present. Press OPTIONS button (switch 4) on Driver Information Center (DIC) and hold. While holding OPTIONS button, press FUEL button (switch 1) 4 times within 10 seconds. System will enter automatic display mode.

In automatic display mode, each system module will be displayed on DIC followed by DTCs that exist in that system. If no DTCs exist, DIC will display NO CODES for that system. If DTCs exist, each DTC will be displayed for 3 seconds followed by a one second pause. If Instrument Panel Cluster (IPC) cannot communicate with any system, DIC will display NO COMM for that system. For diagnosis of no communication fault, see appropriate BODY CONTROL MODULES article. At any time during automatic display mode, manual display feature can be activated by pressing any DIC button except E/M (switch 5). When all systems have been checked in automatic mode, IPC will display NO MORE CODES for 2 seconds, and will then enter manual mode.

When manual mode is entered, DIC will display MANUAL DIAGNOSTICS for 2 seconds or until any DIC button except E/M (switch 5) is pressed. DIC will then display first system and number of DTCs set in that system, and wait for further instructions. Using DIC buttons, move through system diagnostics as necessary. See DIC BUTTON DIAGNOSTIC FUNCTIONS table. Note power mirror related codes for Right Door Control Module (RDCM) and Left Door Control Module (LDCM) and perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE INDEX table.

When E/M button (switch 5) on DIC is pressed at any time, IPC will exit diagnostics mode. On-board diagnostics will also be exited automatically if no DIC buttons are pressed for longer than 60 seconds. If no DTCs exist, perform system operation check. See SYSTEM OPERATION CHECK under TROUBLE SHOOTING.
