SAFARI STORME MY14

ELECTRICAL 179 ELECTRICAL STEP FOR DIAGNOSING IMMOBILIZER CAN FAILURE: 1 Disconnect the battery before measuring the resistance 2 Measure the resistance in the diagnostic connector between following pins CAN_H (6) & CAN_L (14) CAN_H( 6) and GND(5) CAN_L( 14 ) and GND(5) CAN_H (6) and Vbatt ( EMS Pin no. B1/B3/B5 ) CAN_L (14) and Vbatt ( EMS Pin no. B1/B3/B5 ) Value Status Value Status Value Status Value Status Value Status 2.1 60 Ω - 70 Ω OK >1K Ω Range OK >1K Ω Range OK >1K Ω Range OK >1K Ω Range OK 2.2 0 Ω - 20 Ω Short circuit between CAN_H and CAN_L 0 Ω - 20 Ω Short circuit between CAN_H and GND 0 Ω -20 Ω Short circuit between CAN_L and GND 0 Ω -20 Ω Short circuit between CAN_H and Vbatt 0 Ω -20 Ω Short circuit between CAN_L and Vbatt 2.3 110 Ω - 130 Ω Either EMS or BCM is not connected or open circuit on main CAN bus - - - - - - - - 2.4 >1K Ω Range EMS and BCM both are disconnected. - - - - - - - - 2.5 >1M Ω Range 1. Check continuity between CAN_H(6) CAN_H( B53 ) on EMS ECU 2. Check continuity between CAN_L( 14 ) CAN_L( B54 ) on EMS ECU >1M Ω Range 1. Check continuity between CAN_H (6) with CAN_H ( B53 ) on EMS ECU. 2.Check continuity between GND(5 ) with GND( B2/ B4/B6) on EMS ECU >1M Ω Range 1. Check continuity between CAN_L ( 14 ) with CAN_L ( B54 ) on EMS ECU. 2. Check continuity between GND(5) GND( B2/ B4/B6 ) on EMS ECU >1M Ω Range 1. Check continuity between CAN_H (6) CAN_H ( B53 ) on EMS ECU. >1M Ω Range 1. Check continuity between CAN_L ( 14 ) with CAN_L ( B54 ) on EMS ECU.
