Pinpoint Test 18: DTC C1947 - Front Driver's Seat Track Position Switch Circuit Short to Ground
PINPOINT TEST 18: DTC C1947 - FRONT DRIVER'S SEAT TRACK POSITION SWITCH CIRCUIT SHORT TO GROUNDNormal Operation
The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects a short to ground, it will store DTC C1947 in memory and send a message to the instrument cluster module to illuminate the air bag warning indicator. If the RCM detects a short to ground on the driver seat track position sensor circuit, it sets DTC C1947 Front Driver's Seat Track Position Switch Circuit Short to Ground.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Driver seat track position sensor
- RCM
WARNING:
- Remove restraint system diagnostic tools from the vehicle prior to road testing. If tools are not removed, the supplemental restraint system (SRS) device may not deploy in a crash. Failure to follow this instruction may result in serious personal injury or death in a crash and possibly violate vehicle safety standards.
- Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of serious personal injury or death.
CAUTION: Use the correct probe adapter(s) when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE:
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- Supplemental restraint system (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
- Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the Pinpoint Test.
