Diagnostic for:
102/001 error code (CAN code is 0x5038) absolute range error
• Check the lift potentiometer mechanical movements, connections, and check for secure mounting.
• Check the lift potentiometer cable (W203), cable connection to Lift Board J11.
• Reconnect the W203 cable connector from Lift Board J11, measure the lift potentiometer resistance
continuity on the connector: between pins 1-3, 1-2, 2-3, moving the lift potentiometer shaft manually.
• If a fault is found, change the lift potentiometer (see Job Card D/R A204 - Lift Potentiometer on page
1175) and cable.
• If the lift potentiometer unit is good, change the Lift Board (see Job Card D/R A201 - Lift Board on
