Inspection and testing of glow plugs (Freelander 2)

CAUTION: Diagnostics by substituting a component from another vehicle is NOT permitted. Substituting control modules does not guarantee confirmation of the fault and, in addition, may cause additional faults in the vehicle being tested and/or in the vehicle from which the modules are removed.

1. Perform a visual inspection for obvious signs of damage.

Electrical factors:

• Fuse(s)
• Glow Plug Relay
• Engine Management System Relay
• Wiring harness
• Electrical connector(s)
• Glow plug(s)
• Engine Control Module (ECM)

2. If an obvious cause for the problem you identified or the customer described is found, correct it (if possible) before moving on to further action.

3. If the cause is not visually obvious, clarify the symptom of the malfunction and refer to the Index diagnostic trouble codes (DTC).
