Overview

The mirror operation is controlled by three different modules, the automatic temperature control module, the body control module and the seat memory control module.

Mirror heating is controlled by the automatic temperature control module, so there will be some cross-over with the climate control section as far as diagnostic trouble codes (DTCs) are concerned.

For information on the description and operation of the mirrors, refer to the relevant section of the workshop manual.

Inspection and Verification

. Verify the customer concern.

. Visually inspect for obvious mechanical or electrical faults.

Mechanical Electrical
  • Door mirror switch condition and installation
  • Door mirror condition and installation
  • Battery condition and state of charge
  • Fuses Battery junction box (BJB) - fuse 12E Battery junction box (BJB) - fuse 16E Central junction box (CJB) - fuse 5P Central junction box (CJB) - fuse 16P Central junction box (CJB) - fuse 33P Central junction box (CJB) - fuse 46P Central junction box (CJB) - fuse 69P
  • Harnesses and connectors
  • Washer jet and mirror heater relay
  • Memory control module(s)
  • Door mirror switch(es)
  • Door mirror motor(s)
  • Ignition switch
  • Battery junction box (BJB)
  • Central junction box (CJB)
  • Automatic temperature control module
  • Local interconnect network (LIN) circuit

. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step

. Use the approved diagnostic system or a scan tool to retrieve any DTCs before moving onto the symptom chart or DTC index.
  Because the DTCs are stored in more than one module, a complete vehicle read is recommended.
Because the DTCs are stored in more than one module, a complete vehicle read is recommended.
  Make sure that all DTCs are cleared following rectification.

Symptom chart

Symptom Possible causes Action
Mirrors do not defrost/washer jets freeze
  • Fuse fault
  • Washer jet and mirror heater relay fault
  • Circuit fault: high resistance
  • Circuit fault: short circuit to ground
  • Automatic temperature control module fault
Check the fuses. Check the operation of the washer jet and mirror heater relay (see the visual inspection). Check the washer jet and mirror heater circuits. Refer to the electrical guides. Refer to the warranty policy and procedures manual if a module is suspect.
Mirrors inoperative in one or more directions
  • Mechanical fault
  • Switch fault
  • Motor fault
  • Circuit fault: high resistance
  • Circuit fault: short circuit to ground
Operate the mirror switch and listen for the motor(s). If the motor(s) can be heard, check the mechanical condition of the mirror and linkages. Rectify as necessary. Check for DTCs indicating a switch, motor or circuit fault.
Memorized mirror position is not resumed
  • Battery voltage below 10.5 volts
  • Position not stored
  • Switch operated during "one-touch" memory recall
  • EEPROM fault
Before condemning a memory component, check the function from the switch and refer to the symptoms above. Make sure the battery voltage is adequate. Make sure that the desired position is correctly stored. Make sure that the memory store/recall procedure is being followed. Refer to the relevant section of the workshop manual.
'Lazy entry' function inoperative
  • Remote transmitter fault (battery, transmitter programming, etc)
  • See list for "position is not resumed"
Check that the remote transmitter operates the central locking, etc. If it does, the fault is not with the transmitter. Refer to "position is not resumed".

DTC index

:
  Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).

:
  For a full list of climate control DTCs, refer to section 412-00, Climate Control Section of the workshop manual.

DTC Description Possible causes Action
B1B8541 Memory Control Module
  • Seat module error
Renew the seat memory control module. Refer to the warranty policy and procedures manual if a module is suspect.
