TEST CONDITIONS DETAILS/RESULTS/ACTIONS
A1: CHECK THE POWER SUPPLY TO THE PSE MODULE
1
Disconnect PSE Module C1268.
2
Ignition switch in position I.

3
Measure the voltage between the PSE module C1268 pin 4, harness side and ground and the PSE module C1268 pin 5, harness side and ground.

Is the voltage greater than 10 volts?
Yes
GO to A2.
No
REPAIR the circuit(s). Test the system for normal operation.
A2: CHECK THE PSE MODULE GROUND CIRCUIT
1
Ignition switch in position 0.

2
Measure the resistance between the PSE module C1268 pin 3, harness side and ground and the PSE module C1268 pin 6, harness side and ground.

Is the resistance less than 5 ohms?
Yes
CLEAN the cellular phone handset holder contacts. TEST the system for normal operation. If the concern persists, INSTALL a new cellular phone handset holder. TEST the system for normal operation. If the concern persists, INSTALL a new PSE module.
No
REPAIR the circuit(s). Test the system for normal operation.

PINPOINT TEST B : REDUCED SOUND OR NO SOUND THROUGH THE SPEAKER

Yes
CLEAN the cellular phone handset holder contacts. TEST the system for normal operation. INSTALL a new cellular phone handset holder. TEST the system for normal operation. If the concern persists, INSTALL a new PSE module. TEST the system for normal operation.
No
INSTALL a new cellular phone speaker. TEST the system for normal operation.

PINPOINT TEST C : NO SVC DISPLAY STAYS ON
TEST CONDITIONS DETAILS/RESULTS/ACTIONS
C1: CHECK THE CELLULAR PHONE HANDSET HOLDER ANTENNA CABLE FOR OPEN
1
Disconnect Cellular Phone Handset Holder Antenna Cable.

2
Measure the resistance between the center pin of the cellular phone handset holder antenna connection and the center pin of the antenna cable connector.

Is the resistance less than 1 ohm?
Yes
GO to C2.
No
INSTALL a new cellular phone handset holder. TEST the system for normal operation.
C2: CHECK THE CELLULAR PHONE HANDSET HOLDER ANTENNA CABLE FOR SHORT

1
Measure the resistance between the center pin of the cellular phone handset holder antenna connection and the outer contact of the cellular phone handset holder antenna connection.

Is the resistance greater than 10,000 ohms?
Yes
GO to C3.
No
INSTALL a new cellular phone handset holder. TEST the system for normal operation.
C3: CHECK THE CELLULAR PHONE ANTENNA CABLE FOR SHORT
