Signal Missing or Faulty. Intermittent Fault.
Signal missing or faulty. Intermittent fault.
Checking start
Try to start the car with all the customer's keys.
One of the following may occur:
1. The engine starts with all keys
2. The engine starts with at least one of the keys.
Select one of the above response options.
1 - Communication
2 - Checking the key type
-------------------------------------------------
Communication
Hint: The fault was due to a temporary disruption in communication between the transponder and the central electronic module (CEM) or a key that is damaged, does not belong to the vehicle or has not yet been programmed into the central electronic module (CEM) has been used to try and start the vehicle.
Note! Check to see if there are several keys (with transponders) on the same key ring. These keys should be separate so that they do not touch the key being used. Also check that no other transponder, such as an electronic door key or an identity card with an integrated transponder, is near by.If there is an automatic toll road transponder in the car, this should be positioned as far from the antenna unit as possible.
Continue - Verification
-------------------------------------------------
Checking the key type
Visually check to see if the key in the ignition switch is the correct type. See the illustration.
Check that the colour marking (a small semi-circular plastic marking positioned on the head of the key nearest one of the short sides of the metal section) is the correct colour: The correct colour is gray or red.
The key is for another type of Volvo if the colour marking is black or blue.
If the colour is not correct, replace the key with the colour marking as above. Insert the key in the ignition switch. If the key with the correct colour marking is missing order a new key. Program the key(s). See Key, add / remove Add or Remove Key.

Checking the key code
Note! Check to see if there are several keys (with transponders) on the same key ring. These keys should be separate so that they do not touch the key being used. Also check that no other transponder, such as an electronic door key or an identity card with an integrated transponder, is near by.If there is an automatic toll road transponder in the car, this should be positioned as far from the antenna unit as possible.
- Ignition on
Read off the CODE RECEIVED parameter to see if the key code has been received by the central electronic module (CEM).
If the code has been received Yes is shown.
Has the code been received?
Yes - Checking the stored code
No - Damaged transponder
-------------------------------------------------
Damaged transponder
The key has a damaged transponder.
Order new key(s). Program the key(s). See Key, add / remove Add or Remove Key.
Continue - Verification
-------------------------------------------------
Checking the stored code
- Ignition on.
Read off the CODE STORED parameter to see if the key code has been stored in the central electronic module (CEM).
If the code has been stored Yes is shown.
Check all the keys belonging to the car.
Make a note of the keys that are not stored.
Is the code stored for all keys?
Yes - Verification
No - Programming keys
-------------------------------------------------
Programming keys
Program the key(s) which displayed NO, when CODE STORED was read off. See Key, add / remove Add or Remove Key.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).

Yes - Attempt New Test
No - Fault Found
