Checking TCS Lamps

Checking TCS And TCS OFF Lamps

Fault Symptom
- The lamps do not light or stay lit without a diagnostic trouble code being generated.
(Note that the lamps are tested for 3 seconds when the ignition is switched on)

Action
1 Activate the lamps using the ISAT "ACTIVATE" menu.
- If the lamps do not work, first check that the lamps are not broken.
- If the lamps are intact:
Check the Traction Control System (TCS) lamp lead for breaks or shorts between control module pin 12 and pin 4 on the instrument.
Alternatively check the TCS OFF lamp lead for breaks or shorts between control module pin 26 and pin 12 on the instrument.
- Remedy any faulty lead.
