Control Modules - General Diagnostics and Tests (544 Body): Other Volvo S40 II рестайлинг

CHECKING THE POWER SUPPLY AND GROUND TERMINALS

Voltage supply, parking assistance module (PAM)

The parking assistance module (PAM) is powered via a power input on the control module.

Power input terminal #A1 is +15-supplied via the central electronic module (CEM) and a fuse from the ignition switch. The ignition switch is powered from the battery via the integrated relay/fusebox in the engine compartment. In the event of an open-circuit, park assist cannot be activated.

Checking the power supply

Check the power supply cable from the central electronic module (CEM) to parking assistance module (PAM) terminal #A1. Check for an open-circuit. Check for loose connections. Check for contact resistance. Check for oxidation. Also check the power supply from the battery via the integrated relay/fusebox and the ignition switch to the central electronic module (CEM). Check the fuses. The voltage must be approximately battery voltage.

Ground terminal, parking assistance module (PAM)

Parking assistance module (PAM) has a ground input. The ground input from the control module is power ground and is connected to the ground terminal in the car body. See the relevant wiring diagram for further information about the ground terminals in the bodywork.

Checking the ground terminal

Check the ground lead between parking assistance module (PAM) terminal #A8 and the ground terminal. Check for an open-circuit. Check for loose connections. Check for contact resistance. Check for oxidation. With the ignition on, the drop in voltage between the ground connection for the control module and the ground terminal must not be greater than 0.5 V.

Remedy as necessary.

Check the power supply cable from the engine compartment fusebox and the central electronic module (CEM) terminal #E22 (22). Check for an open-circuit. Check for loose connections. Check for contact resistance. Check for oxidation. Check the fuse. The voltage must be approximately battery voltage when the ignition is on.

Check the power supply from the central electronic module (CEM) terminal #A41(41) and keyless vehicle module (KVM) terminal #C4 (#B4). Check for an open-circuit. Check for loose connections. Check for contact resistance and oxidation. Also check the fuse on the central electronic module (CEM). The voltage must be approximately battery voltage.

Ground terminal, keyless vehicle module (KVM)

The keyless vehicle module (KVM) has a ground input. The control module is grounded in the B-post on the corresponding side where the control module is installed. See the relevant wiring diagram for further information about ground terminals.

1. Ground input terminal #C5 (#B5) is power ground and is connected to the ground terminal in the car body.

Checking the ground terminal

Check the ground lead between the keyless vehicle module (KVM) and the ground terminal. Check for an open-circuit. Check for loose connections. Check for contact resistance. Check for oxidation. With the ignition on, the drop in voltage between the ground connection for the keyless vehicle module (KVM) and the ground terminal must not be greater than 0.5 V.

Scheme 1

1. Ignition off.
2. Remove fuse FX in the Central electronic module (CEM).
3. Release the Keyless vehicle module (KVM), See : «KEYLESS VEHICLE MODULE (KVM) (2005-2011)»(ref-460884-S18555340142012033000000)
4. Disconnect the connectors from the Keyless vehicle module (KVM).
5. Check in particular that the male and female terminals on the control module and the control module connector are intact, secure and cannot be pressed in. Check that the female terminal cables are securely connected
6. Especially check the pins that are in question for the diagnostic trouble code/symptom. See «SIGNAL SPECIFICATION (2005-2007)»(ref-460883-S36271107472012033000000)
7. Connect adapter «9512906»(ref-460875-S08021830602012033000000) to the connectors for the Keyless vehicle module (KVM) and connect breakout box «9511428»(ref-460875-S19859279082012033000000) to the adapter. NOTE: Before the control module functions can be checked and measurements taken, the removed fuses must first be installed.
8. The breakout box is designed to facilitate the reading of control module input and output signals when the control module is connected as well as the resistance of cables and components when the control module is disconnected. Using the breakout box reduces the risk of unintentionally short-circuiting cables or damaging pins in the connectors.
