Pinpoint Test E: Steering Wheel Module Local Interconnect Network Wiring Harness Checks
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
- E1: STEERING WHEEL MODULE LOCAL INTERCONNECT NETWORK VOLTAGE CHECK
- Measure the voltage between the clockspring electrical connector (steering column side, BCM LIN circuit), harness side and ground.
Is the voltage greater than 0 volts and less than battery voltage?
Yes
GO to PINPOINT TEST H .
No
GO to E2
- E2: STEERING WHEEL MODULE LOCAL INTERCONNECT NETWORK CHECK FOR SHORT CIRCUIT TO GROUND, SHORT CIRCUIT TO POWER, OPEN CIRCUIT OR HIGH RESISTANCE
- Disconnect Clockspring electrical connector (steering column side).
- Measure the voltage between the clockspring connector (steering column side, BCM LIN circuit), harness side and ground.
Is the voltage greater than 0 volts and less than battery voltage?
Yes
GO to PINPOINT TEST G .
No
Refer to the electrical circuit diagrams and check the BCM LIN(LIN 1) circuit (BCM to clockspring) for short circuit to ground, short circuit to power, open circuit, high resistance. REPAIR the circuit as necessary. TEST the system for normal operation.
