Pinpoint Test
- CHECK THE APIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: APIM.
- Ignition ON.
- Measure:
APIM Ground C2383 Ground Pin Circuit Measurement Pin Circuit 1 SBP29 (GY/RD) - -
Is the voltage greater than 11 volts?
- Yes: GO to 2 .
- No: VERIFY the BCM fuse 29 (20A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS .
- CHECK THE APIM GROUND CIRCUITS FOR AN OPEN
- Ignition OFF.
- Measure:
APIM Ground C2383 Ground Pin Circuit Measurement Pin Circuit 37 GD214 (BK/BU) - -
Is the resistance less than 3 ohms?
- Yes: GO to 3 .
- No: REPAIR the circuit.
- CHECK THE HS-CAN
CIRCUITS BETWEEN THE APIM AND THE DLC FOR AN OPEN
- Measure:
APIM DLC C2383 C251 Pin Circuit Measurement Pin Circuit 53 VDB04 (WH/BU) 6 VDB04 (WH/BU) 54 VDB05 (WH) 14 VDB05 (WH)
Are the resistances less than 3 ohms?
- Yes: If the vehicle is equipped with an 8-inch touchscreen, GO to 4
.
If the vehicle is not equipped with an 8-inch touchscreen, GO to 5 .
- No: REPAIR the circuit in question.
- Measure:
- CHECK THE MS-CAN
CIRCUITS BETWEEN THE APIM AND THE DLC FOR AN OPEN
- Measure:
APIM DLC C2383 C251 Pin Circuit Measurement Pin Circuit 16 VDB06 (GY/OG) 3 VDB06 (GY/OG) 17 VDB07 (VT/OG) 11 VDB07 (VT/OG)
Are the resistances less than 3 ohms?
- Yes: GO to 5 .
- No: REPAIR the circuit in question.
- Measure:
- CHECK FOR CORRECT APIM OPERATION
- Ignition OFF.
- Disconnect and inspect the APIM connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the APIM connector. Make sure it seats and latches correctly.
- Operate the system and determine the concern is still present.
Is the concern still present?
- Yes: CHECK OASIS
for any applicable TSBs
. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs
address this concern, INSTALL a new APIM:
REFER to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) (Premium),
REFER to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) (Premium Plus), or
REFER to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) (Sony® Sound).
- No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
