Connector Codes

(LB) + (13) + (24)HARNESS CODE CONNECTOR NUMBER PIN NUMBER

: LB13-24 (pin number is separated by a dash)Example

: Absence of a dash and a pin number indicates a single wire connector.Note

Diode Codes

(LB) + D + (5)HARNESS CODE IDENTIFICATION NUMBER

: LBD5 (no dash is used)Example

Ground Codes

(LB) + G + (78)HARNESS CODE IDENTIFICATION NUMBER

: LBG78 (no dash is used)Example

Reference Symbols Reference Symbols

Two reference symbols are used to indicate the remainder of the circuit (feed and ground) and refer the reader to one of two preliminary figures.

Reference Flags

This symbol refers the reader to a figure number only. It does not refer to a flag with the same number on a different figure.

As used in figures 1, 2 and 3, the FLAG refers to a figure number where the circuit is continued. In this instance, the reader matches the BOX orDIAMOND numbers to trace the circuit.

In most other cases, it is not necessary to refer to another figure for completion of a circuit. The FLAGS are used to indicate parallel circuits andcircuits which share components. Most of the circuits where this situation occurs are overlapped to avoid the necessity for cross-referencing toanother figure.

Splice Codes

(LB) + S + (3)HARNESS CODE IDENTIFICATION NUMBER

: LBS3 (no dash is used)Example

Seat Control Module - Loss of Seat or Mirror Functions - Repair Procedure

MODEL XJS Range 1994 MY VIN 190528 - 192880 DATE 7/95 ISSUE:

Loss of any driver seat adjustment, door mirror adjustment, or any combination of seat and mirror adjustments in 1994 MY XJS Range vehicles fromVIN 190528 - 192880, may be caused by a failure of the seat control module (SCM). If a function fails, it would cause the adjustment that it controls toremain at its last set position. To prevent repeat failure of the SCM, the mirrors must also be replaced. ACTION:

If the seat control module fails on a 1994 MY XJS Range vehicle within the VIN range listed above, BOTH door mirrors must be replaced with revisedmirror units when the SCM is replaced.

: NOTE

A production change within the VIN range added capacitors to the door mirror motors. The capacitors, which were added to reduce radiointerference, may induce an electrical resonance in the mirror circuit causing SCM failure.

Driver's Seat and Mirrors Control Module -Loss of Seat or Mirror Functions -Repair Procedure MODEL: Sedan Range 1994 MY

VIN 687219 - 701123 DATE: 4/95 ISSUE:

Loss of any driver seat adjustment function, door mirror adjustment function, or any combination of seat and mirror adjustment functions in 1994 MYSedan Range vehicles from VIN 687219 - 701123, may be caused by a failure of the driver's seat and mirrors control module (ECM). If a function fails,it would cause the adjustment controlled by that function to remain at its last position. To prevent repeat failure of the ECM, perform the followingaction. ACTION:

If the driver's seat and mirrors control module fails on a 1994 MY Sedan Range vehicle within the VIN range listed above, BOTH door mirrors must bereplaced with revised mirror units (left mirror, part number HMD 3043AC) (right mirror, part number HMD 3042CC) when the ECM is replaced.

: NOTE

A production change within the VIN range added capacitors to the door mirror motors. The capacitors, which were added to reduce radiointerference, may induce an electrical resonance in the mirror circuit causing ECM failure. The supply of revised door mirrors is limited. Use revised mirrors ONLY on vehicles that have a failure of the control module. PARTS INFORMATION: Do not order revised mirrors for dealer stock. Please order on a VOR basis only.

Seat Control Module - Loss of Seat or Mirror Functions - Repair Procedure

MODEL XJS Range 1994 MY VIN 190528 - 192880 DATE 7/95 ISSUE:

Loss of any driver seat adjustment, door mirror adjustment, or any combination of seat and mirror adjustments in 1994 MY XJS Range vehicles fromVIN 190528 - 192880, may be caused by a failure of the seat control module (SCM). If a function fails, it would cause the adjustment that it controls toremain at its last set position. To prevent repeat failure of the SCM, the mirrors must also be replaced. ACTION:

If the seat control module fails on a 1994 MY XJS Range vehicle within the VIN range listed above, BOTH door mirrors must be replaced with revisedmirror units when the SCM is replaced.

: NOTE

A production change within the VIN range added capacitors to the door mirror motors. The capacitors, which were added to reduce radiointerference, may induce an electrical resonance in the mirror circuit causing SCM failure.

Driver's Seat and Mirrors Control Module -Loss of Seat or Mirror Functions -Repair Procedure MODEL: Sedan Range 1994 MY

VIN 687219 - 701123 DATE: 4/95 ISSUE:

Loss of any driver seat adjustment function, door mirror adjustment function, or any combination of seat and mirror adjustment functions in 1994 MYSedan Range vehicles from VIN 687219 - 701123, may be caused by a failure of the driver's seat and mirrors control module (ECM). If a function fails,it would cause the adjustment controlled by that function to remain at its last position. To prevent repeat failure of the ECM, perform the followingaction. ACTION:

If the driver's seat and mirrors control module fails on a 1994 MY Sedan Range vehicle within the VIN range listed above, BOTH door mirrors must bereplaced with revised mirror units (left mirror, part number HMD 3043AC) (right mirror, part number HMD 3042CC) when the ECM is replaced.

: NOTE

A production change within the VIN range added capacitors to the door mirror motors. The capacitors, which were added to reduce radiointerference, may induce an electrical resonance in the mirror circuit causing ECM failure. The supply of revised door mirrors is limited. Use revised mirrors ONLY on vehicles that have a failure of the control module. PARTS INFORMATION: Do not order revised mirrors for dealer stock. Please order on a VOR basis only.

Reference Symbols Reference Symbols

Two reference symbols are used to indicate the remainder of the circuit (feed and ground) and refer the reader to one of two preliminary figures.

Reference Flags

This symbol refers the reader to a figure number only. It does not refer to a flag with the same number on a different figure.

As used in figures 1, 2 and 3, the FLAG refers to a figure number where the circuit is continued. In this instance, the reader matches the BOX orDIAMOND numbers to trace the circuit.

In most other cases, it is not necessary to refer to another figure for completion of a circuit. The FLAGS are used to indicate parallel circuits andcircuits which share components. Most of the circuits where this situation occurs are overlapped to avoid the necessity for cross-referencing toanother figure.
