Pinpoint Test CJ: Abs (Anti-Lock Brake System) Module Communication Concern With SUMA (Suspension Control Module A)
Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information.
Normal Operation and Fault Conditions
With the ignition ON, the SUMA sends messages to the ABS module over the HS-CAN2. If the ABS module does not receive these messages within the specified time frame, the ABS module sets Diagnostic Trouble Codes (DTCs). This can be due to a SUMA failure, a circuit failure on the CAN or an excessive load on the network. For information on the messages sent to the ABS module by the SUMA, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
