DESCRIPTION:
The majority of replaced alternators have had no faults with the alternator itself. As stated in VIDA, replacing only the voltage regulator (ACM, Alternator Control Module) is the recommended repair for
an alternator that is not charging correctly.
With this TJ, Volvo Cars of North America (VCNA) is applying its prior approval process for alternator replacement claims submitted on all P1, P2 and P3 vehicles.
Starting with repair order dates on or after March 8th, 2013, the Prior Approval Department must be contacted for authorization codes for any failure of the following alternators.
Part numbers:
- 36000209
- 36000210
- 36050263
- 36050266
- 36000791
- 36001463
- 36001497
- 36001341
The voltage regulator (ACM, Alternator Control Module) does not require Prior Approval.
Additional fault tracing information:
Charging voltage: Normal charging voltage can vary depending on many factors such as battery state of charge, battery temperature, electrical loads, etc The normal range is 13.5-14.8V with an average of 14.2V. In VIDA, "Quick test of alternator function" can be found in Fault tracing->Symptom Related Diagnostic Procedures->372.
Voltage drop:
The total charging system voltage drop should be less than 0.7V. This is a sum of two measurements:
- Voltage drop from the alternator housing to the negative battery post.
- Voltage drop from the alternator B+ terminal to the positive battery post.
LIN (Local Interconnect Network):
- The normal LIN voltage is 7-11V.
- Voltage will be high (close to battery voltage) if the circuit is open.
- Voltage will be low (close to 0) if the circuit is shorted to ground.
- Further LIN information can be found in VIDA: Information->Product Specifications->Design and
Function->37 Cables and fuses->LIN - Local Interconnect Network
- Detailed LIN information including the attached tip sheet is found in Volvo Cars Performance
Academy Course 1367 - LIN Diagnostics
DTCs:
One or more of the above DTCs may be set when there is a fault in the charging system.
