EPS Specification Recognition
Precautions when performing the EPS specification recognition procedure:
• |
Use a diagnostic instrument (GDS instrument) to check whether
the battery voltage is normal before performing the EPS specification
recognition procedure. |
1. |
Connect the diagnostic instrument to the self-diagnostic
connector (16-pin) beneath the crash pad on the side of the driver’s
seat, and then turn on the ignition to activate the diagnostic
instrument. |
2. |
In the GDS Vehicle Type Selection menu, select "Vehicle Type" and "EPS" System, and then opt for "OK."
