Audio Interface Control Module (PAICM) 
Description and Operation 
 
Portable Audio Interface Control Module (PAICM) 
 
 
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not 
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle. 
NOTES: 
 
 
If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty 
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new 
module/component. 
 
 
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). 
 
 
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with 
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into 
account. 
 
 
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests. 
 
 
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion. 
 
 
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the 
cause. Always check for loose connections and corroded terminals. 
 
 
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific 
customer complaint and carry out the recommendations as required. 
 
The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Portable Audio Interface Control Module 
(PAICM). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop 
manual. 
For additional information, refer to: Information and Entertainment System (415-00 Information and Entertainment System - General Information, Diagnosis and Testing).

Module (TEL) 
Description and Operation 
 
Telephone Module 
 
 
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not 
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle. 
NOTES: 
 
 
If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty 
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new 
module/component. 
 
 
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). 
 
 
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with 
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into 
account. 
 
 
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests. 
 
 
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion. 
 
 
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the 
cause. Always check for loose connections and corroded terminals. 
 
 
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific 
customer complaint and carry out the recommendations as required. 
 
The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Telephone Module. For additional 
diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop manual. 
For additional information, refer to: Cellular Phone (415-00 Information and Entertainment System - General Information, Diagnosis and Testing).
