Complaint:
ESP indicator lamp and/or ESP malfunction message in instrument cluster after engine start. The ESP indicator lamp is off when the engine is restarted.

Installation site:

B 25/15, driver seat box

W 1/4, right A-pillar in footwell







































Explanation of attachment:

A: Lift cap (gray) on connector of yaw rate sensor B 25/15.

B: Unclip old ground line (pin 1) and insulate line.

C: Clip in new ground line and engage cap (gray).

D: Route new ground line parallel with frame wiring harness and fasten to W 1/4 (the ground point with fewer ground cables attached).
